Computer powers on, but does not boot [Solved/Closed] whatthisdo - Latest answer on Nov 2, 2012 07:39PM Hello, I've had my desktop computer for about one year now. It is an Acer Aspire E380. On Saturday afternoon, it was going a bit slow so I decided to restart it. However, once it turned off, it will no longer turn on and boot up. The power button usually lights up, but now it does not. But, the decorative words "Aspire" at the bottom of the tower still lights up. The DVD drive still opens, and a few lights blink on start up as usual. The screen is blank. All of the fans seem to go, except for one. It is the one in the center of the computer on top of a group of metal prongs. It spins upon power up but stops. The power supply fan runs, the other fan runs too. I have made sure everything is plugged in, and tried plugging it into different outlets. I can't boot from a CD, the keyboard doesn't turn on and neither does the mouse. As far as starting up goes, everything sounds normal. No beeps or clicks to hint at harddrive failure. Sometimes when I try to start it up nothing comes on but the center fan on the metal prongs (the one that would run for only a few seconds) goes on full blast until I turn it off. If everything seems to be going, what is stopping it from booting up?        

Well, the first thing that might be causing this is your memory card (RAM). Try to remove it and place it in another memory slot on the motherboard. To be sure if your motherboard is still in good working condition, remove the memory card and power on the PC.

You should hear continuous beep sounds. If you hear this then your motherboard is fine. If placing the memory card in another slot does not work then the problem lies with the memory card itself. You will need to replace it. It could also be that some faulting PCI cards are causing this error. Try to remove your PCI cards. Normally a faulting PCI modem causes this type of error. Remove it and then power on the pc. The processor cannot be faulty but still if you want to check it, remove the CPU Cooler fan. Then turn on the PC. Place your finger on the processor for 2 seconds. You should find the processor heating up. Then turn it off immediately. If this works then your processor is good. Remember not to leave it ON for more than 5 secs.

Rem - Jan 8, 2009 05:16AM Hi, i was just wondering if i could ask a question. I have the same problem, i removed the memory (RAM) and turned on the computer and it started beeping quickly and repeatadly till i turned if off. I read somewhere that these beeps tell you whats wrong. Do you know what this cold mean?

DJ AKSHAY - Jan 13, 2009 11:44PM Well, you are right dear. These continuous beep sounds indicate the absence of memory card in the motherboard. If you read my last post, you'll see that this is part of my explanation to test if your motherboard and processor are both in good working condition. Perhaps you are having static problem with the memory card. Well, here is how to proceed: You'll need an eraser, i guess you know what this is. The one which students use. LOL. Yes, in fact you'll need the eraser to remove the static energy found on your memory card. You'll have to rub the eraser on the gold plated part of the memory card (on both sides). That is the part which come into contact with the internal pins in the memory slot on the motherboard. Well, it's not magic. This is how it is done. Then place it back into the memory slot. It should work. If this also does not work then you need to purchase another memory card because if the above fails then you know this one is faulty. Noble_Yorik - Jan 23, 2009 03:00PM DJ AKSHAY, I generally don't reply on forums after I go to them to investigate whichever tech crisis I find myself in. Instead I take it for granted that the great ether of the internet will provide, as though it was assumed on my part that I was entitled an answer. But it would appear that I now have to let slip that convent illusion as I push aside the veil and thank you, as the person, for supplying me with the answer to my problem. My back-up PC, which I keep for XP reasons, worked fine when last I left it, however when I came back to it today the mouse, keyboard, and monitor were not working (no external input/output devices) and that the tower kept beeping on power up. I thought that it had to be the power supply or that some malicious program was gobbing the memory on start-up. However, upon reading your very thorough breakdown of the possible avenues of component failure I realized it was probably the ram, and sure enough after I used an eraser on the gold tines of the ram the computer rebooted fine. So in summation, thank you for your considered and considerate advise. Now if you will excuse my absence I must be off to attend an askewed veil.

Yours Truly, Noble_Yorik joanne › DJ AKSHAY - Feb 15, 2009 08:20PM dj akshay, you're so great!! my computer has had several issues like fuzzy video and static from audio devices for a few months now and just an hour ago it didn't boot until i saw this forum and read about the RAM and eraser! thank you so much Ross › DJ AKSHAY - Feb 24, 2009 11:24AM Hi, I was hoping to fix a laptop (Acer Travelmate 4101WLMi) and I have read all your excellent advice and did the steps. This is what I'm getting: -laptop is plugged in the mains, i press the power button diodes turn on as normally, the cpu fan spins for 5 seconds then stops, no beeps -i can hear the hdd being checked and dvd drive spins and runs normally -built-in display is damaged but on - the ccfl tube light is on, external monitor is not getting any signal -battery doesn't seem to be charged although the charge indicator is on, the laptop wouldn't power on with battery only -the CPU with the fan off is cold What I've tried: -removed HDD and DVD drive, PCI wireless module, the screen and RAM modules still no beeps and same behaviour Is the MB dead or shall i try replacing the CPU? Thanks. DJ AKSHAY - Feb 24, 2009 11:37AM If the Charge indicator is ON then the adaptor must be good. If it does not charge then either the battery is faulty or there is a problem with the motherboard. If the system does not power on properly, you will not get any display. But if the battery is faulty, when you plug the adaptor, it must power up. Try testing the volt output on the adaptor pin which connects into the laptop with the help of a voltmeter. This is to verify if the adaptor is giving proper voltage. Check adaptor output specification on the adaptor itself then inform me. Ross - Feb 25, 2009 12:32PM Thanks, The adaptor is definitely fine, it works great on other acer laptop. I've done CMOS reset several times by holding the power button for 30 seconds, no difference. The MoBo looks physically intact and I've tested RAMs on the other laptop. The only life I'm getting from the system is literally the initial CPU fan spin, HDD and DVD spin up and light indicators stay on. After a while the integrated ATI X600 chipset is getting warm... reese83 - Sep 19, 2009 07:17PM

try holding down the f10 key at boot slayres - Sep 20, 2009 12:39PM Holding down f10 did not work. Still had to hold down ctrl and alt. I guess it's time to my computer tech. Thanks anyway. lomax69i › DJ AKSHAY - Jun 1, 2009 02:40PM Hey DJ AKSHAY. I'm going out of my mind here, 3 days ago, I restarted my PC and had all the wonderful symptoms of the other people in this forum, i researched all the hassles and the first thing I did was change the Power Suppy (ATX 450watte) as I read that a weak voltage link could be the culprit... No luck - exactlty the same problem. I have changed my RAM, taken out all non essential PCI cards including PCI E's, taken the RAM out altogether (no post beeps occuring), Unplugged HDD's and changed them around... Nothing. Eventually, I went out and bought a new ASUS P5 main board AND a new CPU (2.2 Dual Core Intel), and was 100% sure this would work and happy to have more power anyway... Popped everything together with a new power supply and again, the same results - HDD light comes on and stays solid, all fans work, same old story. Again, I took out the RAM, changed the RAM, took out all non essential cards, tried the onboard VGA instead of the PCI E, nothing I'm begginning to think that I am PC jinxed. Please throw some of your astute brain cells my way and see if you could shed some light here? Would really appreciate it. Cheers, Craig DJ AKSHAY - Jun 2, 2009 03:32AM Have you used a new memory card? By the way, the new P5 Motherboard and Dual Core CPU, when you connect it with the power supplywithout the memory card. Does it give the continuous beep sounds? Remember to connect an internal speaker to be able to hear the beep sounds. If you have purchased new parts, they cannot be faulty... When you turn on the system with the memory card in, and after pushing the power button, if the system is working, you'll be able to turn on and off the CAPS & Num LOCK Key. Just turn the keys on and off and if the lights go ON and OFF then your system is working. You might be having a problem either with the monitor or with the graphics card. Inform me about the results...

justine0409 - Jun 29, 2009 09:23PM ive tried to pres the casp lock.. there is no light.. it's suppose to light right??? gerad - Aug 7, 2009 10:24PM I also have this same problem... Just yesterday I turn the PC on, screen is black for a few seconds to a minute, then it starts. But I go to the bathroom and when I come back it's restarted! It got stuck on the very first screen. I even wait for 5 minutes and it's still on that screen. I press F2 to go to the BIOS settings but nothing. It just froze. So I hit reset and the PC still powers up, lights blink and all, but no boot up. Not even the initial screen anymore. No usual beep, nothing. I wait and wait. Nothing. I press the CAPS and Num Lock keys and no light from my keyboard; could that be a motherboard problem? Help would be appreciated. I got a lot of files that need backing up, lol. Thanks! juanfixespcs - Oct 13, 2009 07:21AM Reformat the harddrive and reinstall windows. If this dosn't work try listening to the hard drive and see if it's making strange noises. if so you need to replace the hard drive. GeeZee › DJ AKSHAY - Sep 3, 2009 10:08PM Hi Dj AKSHAY I am having a similar problem, however none of these things tend to work. i reassembled my pc, and it runs fine but send nothing to my monitor. It doesnt say check signal, unless i unplugg it. help? Thanks. PC_TECH_08 › DJ AKSHAY - Jan 14, 2010 03:13PM Just a friendly reminder... " If you have purchased new parts, they cannot be faulty... " This is not and cannot ever be true. Any part ever made has the possibility of being a malfunctioning part before it ever leaves the store shelf. As a computer tech, and owner of my own computer repair and sales store, I have witnessed this time and time again as I have order "new" parts and they have been faulty.

Not to yank your chain as it were, just a friendly reminder that "new" stuff is not ALWAYS new. Have a nice day. kshaun78 › DJ AKSHAY - Oct 20, 2009 12:50AM Dude I jst wanna say thanx. A lot was skeptical that the eraser thing would work but your the man I really need my pc for school and can't afford a new one at the moment,thanx a bundle also if you can help me with this ? My pc is a dell dimension 3100 and I have to cut it on by taking the sleeve off of it internally is there anyway to make it start like a normal pc from the actual power button zyon1989 › Ross - Jul 30, 2009 10:37AM hey Have you solved your problem, I got exactly the same problem on my Acer Aspire laptop. I press the power button, see my power light coming up, I hear everything starting: fans, cd-drive,.... but after a few seconds everything stops working and my screen stays black. When I press my power button, my pc stops immediately, I don't have to press it for like 5 seconds.

It all started when I was surfing the internet, my screen went red-black for a few seconds and eventually staid black. Couldn't do/see anything. So I pressed the power button to shut it down, restarted everything went fine till I was logged in, then the screen goes black again. Restart one time more, I reach the bios and the it goes black again. From that moment, my PC wont start anymore, not even a flashing screen, nor a beep. DJ AKSHAY - Jul 30, 2009 11:45AM Hi, I read about your problem... It seems to me that you have had a virus attack. Take your windows CD and reinstall everything, remember to format the hard disk completely. zyon1989 - Jul 30, 2009 12:09PM Thanks for the quick reply. Even I hear my drive runnig in the start up, the boot CD wont run, I tried my Vista boot CD already and a linux USB drive. Big E › DJ AKSHAY - Jan 18, 2010 11:55PM

Hey DJ, I've ran into some serious problems with my comp. I started getting BSODs so i took procedures liek checking my CPU temp to make sure its not overheating. I bought some new ram, stuck it in there but i still got the freezes and the BSODs. I took the ram back and exchanged it for a new HDD. I put the new HDD in and it worked for a few hours, it actually let me install windows and a few other things before it started to freeze again. I checked event logs and it had a lot of cd-rom errors. I then changed the cd-rom to see if that was the problem but the problem remains. Now i cant even get windows to boot up. When i start my computer up i see the motherboard logo and then it attempts to boot up windows but its no good. Please help, i dont know what to do anymore djboo › zyon1989 - Jan 4, 2010 07:25PM ftao zion 1989 that problem could be a backlight issue on a laptop on a standard desktop could be anumber of things try an external monitor see wat u get if u sort it try 2 email me and let me know at Email Id removed for security Lost1 › DJ AKSHAY - Mar 15, 2009 10:36PM thanks mate, ur a god send!! I was in panic but the eraser on the ram works a charm! An eraser!!!!!! HAHAHAHAHAHHA › DJ AKSHAY - Mar 17, 2009 09:42PM My god you are a genius. after two hours going in circles with HP support another 2 hours searching the web. I mean, bios was frozen at startup, no moniter, drives, no usb nothing, and then the eraser. If you live in FL I owe you a beer. DJ AKSHAY - Mar 18, 2009 09:44AM Hahaahahh, great, a beer!!! What does FL stand for? I live in Mauritius. It's such a nice country. An eraser!!!!!! HAHAHAHAHAHHA - Mar 19, 2009 11:31PM Florida, USA. Other side of the world from the land of the Dodo I'm afraid. Unfortunately, i'm still stuck. I had the same problem (no usb, monitor etc.). At first I powered down, bled power and it would get to the "Sorry, windows did not shut down...Safemode...last known...and the countdown" page but no matter if i let it rundown or picked an option it would lock up. Then after a few tries it went back to no monitor, no USB Etc. I Unplugged everything, even the hard drive, battery reset etc. Pulled memory, beeped ok. The Eraser trick got everything to fire up, but it still hung at the countdown page. I downloaded a Memory Test Image, but it locked up each time during the test. now here is where it gets interesting. I'm running a hp Media, XP with an ASUS PTGD-LA Mobo. everything is stock, no mods. Came with 2, 512 memory. Has 4 slots. I went and bought a new 1 gig memory for it (has four slots and can take 4 gigs total). Put in just the new memory Boom! the Computer worked like new,

everything great. That was yesterday evening. This morning, it was just the fans running full speed, and when i tried to restart, it hangs at the countdown page. Two things: 1. can something be killing the memory? I really believe that if I buy another memory, I can get it to work long enough to pull off my info. 2. Also the Two Jumpers to clear out Bios...My board has just pins, no jumpers at all. Thanks - JSR DJ AKSHAY - Mar 23, 2009 04:27AM Hi bro, whats up? Well, the problem with your system hanging / restarting is all about defective memory card. It can also be that the Windows is corrupt (some files missing), it might be that you have a bad sector in the hard disk and windows is not being able to access its files. I would recommend you backup your important data by taking the hard disk to another PC and connecting it externally by connecting it via an IDE/USB cable or an external enclosure. If you don't have another PC to do this then you can always ask for help from a friend or relative. Hahaha. After backup, perform a FULL FORMAT with the hard disk. Then re-install Windows. If still you get this hanging error then the memory card needs to be changed. I believe you have got a new memory card so I understand that this cannot be faulty. An eraser!!!!!! HAHAHAHAHAHHA - Apr 11, 2009 11:38PM DJ, Just a note to follow up. Problem finally solved. In the end it was a bad moterboard. I don't know why it started working then stopped, but after trying Bios Battery, Cmos reset, processor test, two different new memory cards, and another processor (which is way faster than my old one :) ), Process of elimination and Ebay, I got a new mobo. when I got the old one out and could inspect it, at least 3 capacitors ( i think they are little brown cylinders) were blown and leaking. So it was giving me different problems: sometimes I could get into bios setup, sometimes just fans, sometimes no fans, sometimes windows would hang at the startup screen etc. now everything is working fine. hopefully this helps someone else. since my machine is older, the mobo only cost $60, less than it would be to have someone try and re-solder them, and who knows what else is wrong with it. Thank you again for taking the time to help so many people. (lurkers included). Rickster › DJ AKSHAY - Mar 1, 2010 06:22PM My son has built a computer from scratch and the first 2 PSUs were faulty - so we used the old PSU and up until now it has worked fine - but tonight I put in a brand new PSU and the computer only booted as far the motherboard startup page and no further! So I tried the memory eraser - and yes i worked BUT windows XP showed the opening page but then wouldn't run. So I turned off and back on and this time it's reverted back to the frozen Motherboard page. So is this a memory card, PSU or Motherboard fault? - please help. Thanks

Dara › DJ AKSHAY - Aug 5, 2009 11:21AM DJ, you're the best! 4 months ago, I was switching the graphic cards on my PC. After a few switches, the computer suddenly wouldn't boot up as many described here. Power was on, HD was running, but screen had no signal. I switched back to the original graphic card but the result was the same. I though I had fried my graphic card slot or even the motherboard. It was devastating. A few days ago, I thought I would give it another try before buying another computer at Christmas (yes, I have to wait until Christmas :o ) and search on the Internet for the symptoms and I found you! I was laughing at the eraser on memory idea when you mentioned it, but then I saw others fixing their similar problems with it. I was astounded and would give it a try. And voila, my dead computer came back to live! I read the rest of the posts and know that you are really the best. You helped so many others. Thanks a ton for helping me, too. Best wishes!

Alexis › DJ AKSHAY - Aug 18, 2009 06:38AM Hello, Thank you It works when I used the eraser my computer runs perfectly again Thanks, Alexis Ferandos CMR › DJ AKSHAY - Aug 25, 2009 06:17AM I just wanted to say that I did the eraser trick and it worked for me! I just couldn't believe it, but it solved all my problems. My computer would power on, then power off on its own just a few seconds later then power on again. Then,nothing else. I mean, the HDD's seemed to work, the CD/DVD worked, but I got no picture on the monitor and no sound (beep). I switched my video card with one from another desktop and it didn't change anything. I checked all the connections and I checked for dust, but nothing worked. In the end, I tried the eraser not really beliving it would make the computer work, but I didn't have much to lose and THANK GOD I DID IT!!! I'm still a bit sceptical about the eraser removing static electricity. I think it might be just that the gold plated part of the memory stick was too dirty and cleaning it did the trick. Maybe it is the static electricity, but anyway, I don't really as long as my computer works fine. zame › DJ AKSHAY - Sep 13, 2009 10:34AM Thank u DJ Akshay Sir, My computer had died down and just wont start.

It had xp on but needed a password so I reformatted hdd and tried installing xp home but setup froze so i shut it off from the buton under the power button with a and when i restarted it started beeping before booting up. Then the next day I took out ram, agp card, cd, floppy, cpu, and cmos battery and reinserted them but then it wouldn't beep even if i took out the ram plus I couldn't hear the post beep sound. The specs of the machine are Made by Optima Computer, 384mb sdram (1X128mb+1X256mb), 1.6GHZ pentium 4 cpu, ASUS P4B-MX Motherboard. I tried your eraser trick but with no luck. The motherboard has a green light lit up when the power cord is connected and when the power switch is on. Please help me as this is my only computer and I need it for work. Thanks Karthik P.S: Feel free to email me on subject with provided email address. navyguy › DJ AKSHAY - Jan 16, 2010 11:18AM ERASER TRICK WORKED FOR ME. Who would think the problem was something I couldn't physically see (static electricity)? My PC would eventually boot up after

numerous power on/off. I removed the modem which I have no use for (and you said could be the source of this issue) and also removed the ram and ran an eraser off a #2 pencil across all the gold pins. Put everything back together (minus the modem) and my PC boot right up first try. I noticed this issue when I would try to restart the PC and it would begin it's shutdown process - screen would go blank (monitor would go to "sleep") - and the case would stay on with all lights, fans, and drives running. After using the eraser trick my PC restarts as it should and no longer needs multiple power on/off to boot.

If not, I have a MB problem, correct? If it does, I should replace the memory cards and then remove the video card and try again. At this point, am I waiting for beep again? This unit is only a few months old and was shipped to me from a friend. I have a feeling its the MB, as I've read some not so great reviews on the P5N MB's. Is there any way I can determine if it is definitely the MB, or did a wire come loose during shipping? Just a thought. Thanks in advance for your help.

DJ AKSHAY - Jan 15, 2009 07:42AM Are you having this problem since you received the motherboard? The processor you are using, did you receive it along with your motherboard? Do you hear the continuous beep sound when you remove the memory card, if not then the problem lies either with the motherboard or with the processor. Give me the motherboard's model and everything which is written on your Processor. Give me feedback on the above for me to be able to help you further but don't worry, I have seen all kinds of problems in my life. By the way I am a specialist for ASUS Motherboard in Mauritius. Reviews are there to tell you what faults this motherboard might have during use. sruman - Jan 15, 2009 05:08PM okay. Took out the memory sticks and no beeps. So, we're on to the next step. So, the way that I understand it, is the the motherboard or processor is the issue. Are there any other test to do, or things to look for that may have come "undone" during transit? I hope so, I really like that computer, but again, the more I read about the P5N T Deluxe, the more I'm not liking it. The system info is: Intel Core 2 Quad Q6600 Processor Asus P5N-T Deluxe 780 SLI motherboard 2 x 2GB Kingston RAM BFG 8800GTS OC 320MB Video Card (2 x DVI) w/aftermarket cooler Arctic Cooling Accelero Xtreme Heatsink and Fans (3). DJ AKSHAY - Jan 16, 2009 04:38AM On your motherboard, there are 4 pins from your power supply which connect in there. The colour which you will see is a pair of 2 yellow and 2 black wires next to each other. You should have 12 volts while checking with a voltmeter. The yellow is for +ve and the black wire for -ve. Check if this is working because this is the source power which gives display on your motherboard. Have you performed the processor test? Does it heat up when you remove the fan and press the power switch on your casing. Perform these tests and inform me about the results. sruman - Jan 18, 2009 04:11PM I did the other test, CPU warmed up. There is not a 4 pin hook up from the power supply to the MB. Not sure what to tell

you. There is a 6 pin hookup to directly to the video card from the power supply, but that it. Is there anything else worth testing, or should I write off the MB at this point? Thanks in advance. DJ AKSHAY - Jan 20, 2009 02:19AM Send me your e-mail address and I'll send you the motherboard's picture with the pin connector location highlighted on it. sruman - Jan 20, 2009 04:23PM Email Id removed for security Thanks a million, princess2500 › DJ AKSHAY - May 19, 2009 01:54PM I'm having the same issue as the last person, I have nowhere to plug in the 4-pin black and yellow wires into the motherboard. The computer's fans turn on, the power light comes on but there is no activity happening. Then after about 2 secs it beeps, 2 secs later it beeps again and keeps doing this until I turn it off. I have an emachine that I'm fixing up for my dad. The computer model number is H2341. I know the hard drive is working because I just took it out of another computer and it was working fine. Please help me. My email address is Email id removed for security Shana › DJ AKSHAY - Sep 8, 2009 03:51PM We need HELP, in a bad way. We rely on our computer for homeschooling our 4 children, and it won't boot up! We bought a dell XPS 630i only about 6 months ago, but of course it only has a 3 months warranty, and they will not help us at all. One day we suddenly got a BSOD. Nothing would work. In the BIOS, it didn't even recognize the main hard drive, like it wasn't there. HOWEVER, I install Ubuntu on that drive and it boots up fine. We just would prefer Vista because a lot of the programs we have don't run on Linux, plus it couldn't find the wireless card in Linux, and so on. I attached the main SATA cable to the other hard drive in an attempt to get VISTA installed on that drive. Still blue screen. I pulled the old drive's connections completely (although it's still in the system atm), and guess what? It starts up without a BSOD, and tries to load Vista from the disk, but now it says it needs drivers, which we cannot find at all on any of the disks dell gave us. And we even manually tried to place drivers on. Nothing, no luck. And I suspect the old hard drive is fine, because Ubuntu worked on it. We can't figure out which motherboard the computer uses. Dell won't tell us (this is the last time we EVER buy from Dell). We're at a loss. Can you help? Aremys - Feb 8, 2010 05:27AM Hi, If you are just trying to find out what motherboard you have, you have a couple of options:

1. Open up the case, and try to read the model number from the motherboard. 2. Download a free program called Aida32. This will tell you all you need to know about the computer, including motherboard model and name. Hope this helps Oz › DJ AKSHAY - Oct 15, 2009 11:12AM Hi im havein a problem and i hope u can atleast xplain to me i have a old AMD sempron 3000+ 2gb ram ddr asrock K8N4-E mobo geforce 8600 pci-e and i have a problem that started to show rescently till a week ago my pc was runin fine but after a week when i tried turning it on all powered up but monitor was black i tried trick with eraser tried removein all piece by piece but i didnt hear anny beeps from pc i even exchanged power suply nothing and i was wonderin could my mobo have died on me cose latter i tried removein proc and it looked ok no broken pins nothing so can u tell me pls if u by chance know is then my mobo faulty thx in advance vaineROX › DJ AKSHAY - Nov 26, 2009 11:05AM DJ ASHKAY, Thank you so much. The eraser/ram thing worked for me, EXACT same symptoms as before. THNK YOU Kevin › DJ AKSHAY - Feb 16, 2010 06:48PM I have a AMD motherboard and when I take out the memory sticks it does nothing, still boots with nomonitor, Fans running and everything. I recently tried switching processors, Then when I downloaded a driver and restarted comp, it wouldnt boot, I switched back to my old processor and it didnt boot.. tinker - Jan 22, 2009 08:14AM I have an old Gateway computer (2001) with a similar problem. I hit the power on button. It goes through bootup sequence, looks like its going to boot up properly since everything lights up and disk drives work. The only problem is the cpu fan is not working and it does not boot up. After multiple attempts, some times 20 or more, it finally goes back to normal where the cpu fan starts working and the boot up sequence is completed. At that point it works fine for a week, day or an hour before it freezes up. Then sometimes it boots right up and sometimes it doesn't. Sometimes the power on light comes on amber not green. DJ AKSHAY - Jan 22, 2009 11:25AM You need to replace the CPU fan my dear or else you can say Good Bye to yr computer. The Temperature sensor for your processor is preventing damage to your Processor because the fan are not being able to cool it down properly. Without the fan, the temp can hit above 100 degrees Celsius in less than 5 sec and you know what can be the result of such high temp. When you replace the fan,you'll find your PC working just the way it was before...

tinker - Jan 23, 2009 04:35PM Thank you. What you said makes a lot of sense. I guess I can buy any P4 compatible cpu fan. I tried your MB test and removed the memory modules and I did get a beep so I guess that means the MB is good. I also noticed when the machine freezes up that the fan is spinning like normal and the machine does not shut itself off. The only other thing I notice is that the power supply does not sound even it seems to fluctuate from a steady hum to where it sounds like its reving up and dieing back. Do you think the power supply might also be bad? DJ AKSHAY - Jan 24, 2009 01:40AM Yes, you can buy any P4 compatible cooler fan for your motherboard. Well, if you are sure that it's the fan of power supply that is making this fluctuating sound then its high time you change the power supply also because power supply fan need to run at a steady speed. Apart from high powered power supplies which have a knob to regulate the fan's speed but still the fan itself cannot decide to change its speed by itself. Fran › DJ AKSHAY - Feb 6, 2009 02:34PM I also have a very old gateway computer 1999-2000 almost the same problem with the power button. Once you press the on button nothing happens, so I keep turning on and off but no dice. On top of that a message appears on the monitor to check all cable connections. I'll do that but nothing then once your about to give up on turning on the computer one last try it will eventually turn on but takes a while to boot up. Can you help me hisluckygem - Jan 30, 2009 04:05PM I have the same problem. I think it didn't shut down all the way last night. It does the preliminary & quickly gives the option for the F12 or F2 options but it doesn't work if you try, it just goes to the blank screen. I have a flashing cursor but it won't allow you to type & does not move. When I try to shut down my computer it's as if it's going to sleep or simply restarting, never completely shutting down. However, it will if I hold the power button in long enough (It's really pretty long comparatively speaking) I unplugged from the wall it to see if that would work but even yet sometimes it still goes back to the cursor & black screen & doesn't even seem to start the boot up process. I had this same problem about a year ago & I took it in. The tech said there was nothing really wrong with it, it was just overloaded & from then on it booted up & has worked just fine. Cost me $75 for that. I ran a registry cleaner last night & when it was finished I went through the steps to shut it down but I left before the process had completed. This morning the CPU was frozen & when I restarted it, this is where I am at. Not to backtrack, last time right before this happened my CD Rom & DVD-RW drives stopped working. I want to clean it of all my pics & short home movie clips but it's really not that low on memory, and now I can't get it to recognize a cd or dvd to write

to in the drive. I don't think is shouldn't be doing this with 38 percent memory free. Now, my laptop, that's another story. Every time I remove something it seems as if I lose memory, I never have extra space as I figured I would. Sorry it's so long, I'm having multiple issues here I guess. Please help me with these without losing everything on my CPU. I REALLY can't afford the $75 right now. -ThanksDJ AKSHAY - Jan 31, 2009 02:12AM Concerning your PC, you need to disconnect the cables on your hard disk. Then power on the PC, you should get a message as follows: Insert Boot Device and Press any key... (something like this) If you see this, Press CTRL+ALT+DEL keys to restart your PC and press the F2 function key repeatedly to enter The motherboard's BIOS. Under the Main menu, you should see the names of your CD-ROM and DVD-RW Drives. This means that BIOS detects the two O.D.D. and possible some corrupt files in Windows operating system are causing this error. Turn off your PC. Re-connect your Hard Disk by connecting back the cables and power on the PC. Press F2 again repeatedly to enter BIOS. Now you should be able to see the Hard Disk name also under the Main Menu. Go under Boot Settings/ (for some models you need to go to Advanced Options to find Boot Settings) Make sure that the first boot device is your H.D.D. Press F10 to save changes and exit, press Y for YES. Give me feedback if everything is working as mentioned above so that i can tell you the next steps to follow... doitonline - Feb 12, 2009 05:50AM Thank you Dj, I decided to chek if everything is working properly ie, motherboard test and CPU, i removed the RAM and powered on the laprop, i did not hear any beeps, i know how them bips sounds like so i was sure there is no beep... Does that mean that my Motherboard is Dead>??? if yes what is the best option. The laptop is Acer Aspire 3500, with serial number LXAXE0C00870501F642534, AMDSampron 1.8MHtz. It was formerly Vista but for some reasons the owner did not like it and Installed XP in it, it worked fine for more than six months. Now its not

booting up any CP, i tried the BIOS settings to read DVD RW first and saved the settings, powered on the laptop but same thing happened. it restarts again and again.. Any help? DJ AKSHAY - Feb 16, 2009 02:26AM If you are getting access to the BIOS then the motherboard is good. You should verify the hard disk by connecting it EXTERNALLY via an enclosure to another PC or laptop. I believe if the hard disk is good, you should re-install the Windows. cpoluk - Feb 13, 2009 03:59PM Reading what you said about finding out if the processor is good. I have a computer that won't give me any video I tried getting a new motherboard, but still isn't helping. If I take off the heatsink + fan and turn the computer on for about 5 seconds then feel the processor it is still cold to the touch. This means the cpu is bad? DJ AKSHAY - Feb 16, 2009 02:23AM Does the CPU fan turn? If yes, then your processor is faulty. But we should keep in mind if the motherboard is same generation as the one you had. Does it support the processor that you have? If not it will not heat up even if the motherboard and processor both are good. sothankful - Feb 16, 2009 02:31PM Thank you DJ Ash! I almost threw the white flag up with my hp pc because it was having the same problem. Before taking it in to a professional and spending some $$$ I decided to attempt to fix it myself one more time taking your advice with the RAM. To my surprise it worked! Thanks! You're the best!

I have been reading some of your info on this site and have been impressed with your knowledge. I have a acer e380. Its 2 years old and has been fine until recently. I went to log off and it died. What happens now is when I put power to it the fans run slowly and you can open the cd drive. After I play with the power switch for awhile it comes on with the fans full speed and power still to the cd drive but it can't be opened. Nothing on the monitor, keyboard or mouse. I don't hear the startup beep. Connections all look good. I have removed the ram and reseated same result. I remove the ram and startup still same results no beep of any kind. I am not sure where to go from here. By reading some of your info on thois site I am thinking motherboard, p/s or cpu. What is your opinion and advise what to do next. Thanks for your help. Wayne DJ AKSHAY - Feb 19, 2009 11:20PM Make the Processor test, remove the CPU fan and power up your system, you should feel the processor heating. Note this test should not be carried out for a period of more than 5 seconds or it may damage the CPU.

The power supply is good or else the fans would not turn, your CD Drive would not open and no Power LEDs would light up. Try swapping the memory to another slot. Reset the BIOS, don't forget to remove the power cord while performing the reset. Try disconnecting the CD ROM Drive and Hard Disk after the reset then power on and see the result if there is any change. If still you do not hear a beep then I would suspect a motherboard failure. wadd - Feb 20, 2009 08:47AM How do you reset the bios? Where is this located? Thanks for you assistance.

REE - Feb 24, 2009 12:27AM Computer powers on, but does not boot LindaB - Mar 1, 2009 04:50PM I was wanting to upgrade the memory on my old gateway ev700. Opened it up and it has 2 slots of 128 ( 256 total). I took them out and tried to put in a 512 and a 256 but found they were NOT the right ones. Only had 1 notch in the gold pins instead of 2 notches like the old 128 had. Took them out and put the old 128's back. Power it on and now now monitor, mouse or keyboard. Opened it back up after reading your comment and cleaned with eraser. Still no beeps after powering on. So I took out the 128's and left them out turned it on and ONLY 2 beeps sounded and then nothing. Cleaned the 128's again put them back in and powered on again and still no monitor. Since it only had 2 beeps is that a bad sign? The unit was working fine right before I decided to upgrade the memory ( was running very slow). Should I buy new memory or does the 2 beeps mean something bigger to repair? DJ AKSHAY - Mar 2, 2009 09:45AM The 2 beeps are in relation to the graphics card. Try to reset the BIOS then try again. I believe you have a separate vga card, not onboard otherwise you would not hear the 2 beeps. Remove the VGA card and clean with the eraser and place back in position properly. I hope you did not turn on the system when you placed the memory card with only 1 notch. The fact is that you've purchased a DDR Memory instead of SD-RAM. LindaB - Mar 2, 2009 09:06PM

I am not experienced so I am not sure of your reply. The beep occurs when the cards are out. That is all. I took the 2 memory sticks out( is that what you mean by VGA cards?) cleaned both sides on the copper pins with an eraser. Put them back in and no monitor shows, just the test screen that says it is working properly. No mouse and no keyboard. The 2 memory cards I put back in are the 2 original ones! I MAY have tried to put in one of the DDR's but they did not fit so it was removed. Would that have caused a problem??? Thanks Linda B DJ AKSHAY - Mar 3, 2009 01:37AM As long as you did not power on the system with the DDR Memory which did not fit in the slot, your system is still in good condition. Try to check if in the attempt to try inserting the memory in the slot, you did not damage a PIN in the slot itself. It can be that the pins are shorting each another and this is causing the system not to boot up even with the original memory cards. By VGA, I meant to say the Graphics card. babis_sc - Mar 19, 2009 08:47AM Hi DJ AKSHAY, I have the same problem with the other guys only with a small variation. I had also my computer not giving any sign of post or booting even though the fans, power supply etc were running. I assumed that the motherboard crashed so I decided to buy a brand new motherboard for which I had also to buy a new graphics card and new DDR2 RAM as the new motherborad did not support the old ones. Despite of all these I continue to have the same problem meaning that I installed everything in the new motherboard but I got the same: the fans were on, the power leds were on but no beeps and no post. I did all the tests mentioned in the forum including the heating test of the CPU and the fan test for the power supply and everyting seems to work properly. The only incompatibility I may imagine is that my old power supply has an ATX 20-pin power cord to the motherboard whereas the new motherboard has an ATX 24-pin connector. The manufacturer's guide mentions that the 20pin cord may be used to the 24pin connector of the motherboard without any problem but I' m starting to doudt about this. The motherboard is an MSI 945GCM478 (socket 478) with a P4 3.2 Ghz hyperthreading CPU. Do you have any suggestions? Do I have to get a new 24pin power supply? Did any one else have the same problem? I appreciate all the help I may get. DJ AKSHAY - Mar 23, 2009 04:19AM

Hello friend, Sorry for late reply. Well, what I can say is that it can be that the other motherboard was faulty. After having purchased a new motherboard and putting everything up, it did not work. Perhaps the new motherboard does not support this processor. I mean in the new motherboard manual you will notice a range of compatible processor frequencies that are supported by the motherboard. Try to see if it supports this capacity of processor that you have got. Otherwise I don't see any reason why your system should not work. Nik - Mar 19, 2009 06:13PM I owe you a beer, it was all dirty ram, thank you so much! Best advice I have ever read online. natalia1117 - Mar 22, 2009 01:48PM i was having the same issues, blank monitor, light comes on, fan on, no beeps and i read this post. well i tried the suggestion to remove the memory cards, when i restarted the computer still no beeping. so what iunderstand from your post is that i have a bad motherboard, is that correct? DJ AKSHAY - Mar 23, 2009 04:29AM Do you have an internal speaker connected to the motherboard. Otherwise you will not hear any beep even if there is another problem. 2nd thing, have you performed the CPU HEAT TEST? What was the result? Only then we can determine the problem and the resulting solution... Ok dear? rr_sookoo - Mar 11, 2010 02:08AM First off, I'd like to compliment you on your vast knowledge, DJ. I was changing the HDD of my system (previous on went bad). When I finished, I powered up the PC, all I am seeing now is the manufacturer's logo. It would not go past that point, even though I tried everything posted on here. Power Supply fine Processor works fine. Hard Disk works fine All RAM Cards are fine Optical Drives Ok Speaker Works This was all tested by inserting them into another, similar PC system. Upon Removing the RAM cards, I'm getting the beep errors - so I know, to some degree, that the Mobo is

working. Any views, opinions, suggestions ????

I tried everything you posted and I haven't pinpointed the problem yet. Everytime I plug the system or power it on, the green power light comes on in front and both the system and CPU fan run on high and nothing is displayed on the moniter. I hold down the power button to shut it down, and when I turn it back on the process stays the same., I have power going to the CD drive, mouse and keyboard. I didn't hear any beeps after I stripped it down and took out the memory cards, I tried using a new one in a different slot with no luck. Do you have any other suggestion before I go out and buy a new mobo? I would greatly appreciate any recommendations.

Thank you. DJ AKSHAY - Apr 27, 2009 11:02AM

Well dear, I suspect a motherboard failure. Only a motherboard having a corrupt BIOS does like what you have just explained. 1 solution would be sending it back to ASUS to repair it and they will send it back to you after the repairs which I believe will not cost you much. It's up to you now to decide about what you'll do, repairing it or just buy another one. k.stalker - May 4, 2009 05:22AM hi dj bin a while old mobo done bought a new 1 but to get the ram workin i had to put it into the right set of slots just wonderin wat u think it cud b i 've 12 months warrenty also i was wanderin if it was possible to replace a damaged 775 socket on an asus p5kc DJ AKSHAY - Jul 16, 2009 11:42PM For this, you will need to send the motherboard to ASUS where they will change the socket. I believe this will not cost you much. Normally under these circumstances we send them for repair. harbatross - Jan 26, 2010 08:24AM what causes cpu not identify the vga all not transport the signal to the monitor Sharad - May 15, 2009 10:11AM Hey akshay thanks a lot man . just removing the RAM and placing it again did the trick :) GR8!

DJ AKSHAY - Jul 16, 2009 11:26PM Normally you should use the eraser on the memory card because most of the time it's due to static energy presence or due to humidity. If this does not work then I suspect the motherboard is faulty. IRV - May 18, 2009 12:38PM Thank you...

Thanks Arash chris mccall - Aug 21, 2009 03:31PM Hi There I so hope you can help me. few days ago switched on laptop (fujitsu-siemens amilo li 2727) night after installing digi camera. what I got was the BSOD!!! in the end I have formatted the drive & installed vista again. problem now is I cannot boot up in normal mode or safe mode. or at all. when I boot up I get the microsoft (MS) page with the timer. little gold bars move to other end of the timer then I get a reboot. If I disable the EXEXUTE-DISABLE BIT CAPABILITY I get the gold bars to come & go ten times then my mouse pointer appears for 2-3 seconds later it crashes out. back to the start.

I can access the hard drive if I use a vista restore disk, then run repair (which it says its a hareware problem cant repair this problem). I then select the command prompt, type notepad into the cmd line then select file then open, I can do all sorts from here delete, copy, move ect. (this makes me think the HD is fine). I can also run a disk called german police boot cd which loads fine & I get into the desktop only its XP pro on it. this makes me think the memory is fine as the CD loads onto memory fine. but problem still works afterwards tests I have done:removed the RAM - got no beeps but the screen wont start. cleaned the terminals - still nothing tried the touch test on the processor - get HOT!!! ouch! CD drive runs fine removed the CMOS battery power is fine screen is fine fan runs fine keyboard works fine changes the BIOS setting switched off USB legacy & wireless nothing plugged in to any sockets I did see the thing about the CMOS reset but im not too sure what exactly im looking for. as you can see I think Im nearly out of options but Im not giving up & paying a techi YET!!!!

Thanks, Subham LUCKY - Oct 25, 2009 03:09PM i packed away my desktop while i brought it in tha other day and let it set cuzs of the cold to warm it up while now all it does when i turn it on is beep is there something more wrong with it. devonl - Nov 27, 2009 04:46AM Awesome advice DJ Akshay, your advice worked perfectely - you saved me alot of money and frustration ! TechnicalFoul - Dec 1, 2009 05:46PM Hi. Came across this post today after finding out that my computer powers on but get no response from monitor, keyboard, or mouse, no beeping sound either. I saw how many people followed your advice so I decided to give it a try. I removed my memory cards but heard no beeping sounds, so it could be the processor or the motherboard. I took off the cpu cooler and felt the chip for many seconds but it didn't heat up. What I want to know is if it necessarily means that my cpu is broken or is it possible that the motherboard is broken which causes the cpu not to start. Please help me. And thanks in advance. Anonymous User - Dec 6, 2009 12:04PM Hey DJ, I've read your posts helping all these people and am here to beg of you to help me (i dont usually beg lol) out. My problem is that last night I shutdown my pc as usual and then turned it back on this morning (before college), but when i pushed the power button there was no bleep and no signal to monitor and nor the keyboard or the mouse lit up or worked. I opened up the tower and everything seemed fine, fan spinning, dvd drive open and closed but nothing else worked i.e usb mouse lit up neither did a usb keyboard. I cant get into the recovery options, i cant boot from disc it just wont budge.. Its an Acer Aspire M1640 and not even a year old (warranty's void as i upgraded ram and a new hdd). Intel dual core and vista premium. (if any of that helps) Please can you help me as all of my course work is on that pc and i cant lose it, i'd most deffinately fail without it which is why i pprementioned me begging of your help. I tried the eraser thing you mentioned and I cleaned it from inside out and removed the newly installed hardware but still no screen or windows.. I anxiously await you reply Thanks in advance..

I removed the memory cards(one at a time) and turned on my laptop but i didn't get that annoying beeping. Does this mean mymotherboard is messed up. MIGUEL - Jan 7, 2010 09:05PM tyou. saveme a lot money mram01 - Jan 16, 2010 07:29PM i have a hp pavilion dv2418nr notebook i replaced my motherboard since i heard that they usually go bad on these models.. it worked fine for about a day and then it was back to the way it was before: no video and no booting up at all i tried an external monitor via vga to see if the lcd was faulty but no luck i tried a new stick of ram and still no good does the processor test apply to notebooks too? do you think this could be it? i do remember that when it was working i updated the bios on the notebook, would this have anything to do with it? i heard that if you remove the cmos battery for 30 seconds it resets your bios? thanks in advance thanks, dj! - Jan 19, 2010 01:08PM My computer had the same problem, I switched the RAM to the other slot and now it works fine! Awesome, thanks so much! ibnflorida - Jan 30, 2010 11:45AM Thank you so much DJ AKSHAY I have been posting all over the internet trying to figure out my problem with my computer asking how to tell if my motherboard is cpu has gone bad. Ran across your post and found out they were both still good and seen where you said to check pci cards and my modem went bad. TY TY TY feebl - Feb 17, 2010 10:22AM

It worked! By putting my RAM into another slot (I have 4 slots, and 2 RAMs both containing 1 GB) my computer booted again. So I think my slot is corrupt? Mogul - Feb 26, 2010 09:12AM Dear DJ Thank you very much for this answer. my problem is solved in few minutes and i saved at least £50 and lot of time. My PC become okay when i removed modem. Also i used technique to check the Processor and Motherbord. You are so great....... eazy - Feb 26, 2010 06:37PM Thanks! I swapped my memory cards out and my comp is finally working! DM - Mar 20, 2010 04:35AM Hi, I have similar problem. When the screens goes blank, I solve the problem by removing 1 GB RAM, now I have 2 GB instead of 3. 3 GB works some minutes then the screen turns blank. 2 GB works always. I changed the RAM and now I'm using 2 GB RAM. I have AMD athlon 64 x2, 5000+, I should have 3 GB RAM but now it's working only with 2. I changed the video card to a new one it didn't help. I cleaned the video card drivers and reinstalled Nvidia drivers again it didn't help. The only thing helpds to go down from 3 to 2 GB RAM. I have Nvidia 8600 GS. Do you know any suggestion how can I solve this problem? Regards hellfish - Mar 20, 2010 04:32PM Your troubleshooting helped me fix my non-working pc. Turns out one of my shared memory sticks was bad. Many thanks! DM - Mar 21, 2010 02:41AM Hi Again, Now I'm utilizing 3 GB RAM, 2+1, this 1 GB memory I tried in different slots and now I know which slot works for 1 and for 2 GB. The only problem that I have now is when I install Battelfield bad company2, and when I start to update with the latest version of this game then the screen turns black. is this something to do with GC card, RAM or motherboard?? Regards Mark - Mar 21, 2010 08:32PM thank you sir, it was a faulty pci modem card, which I never even used. I just removed it and it works now! Priisa - Mar 23, 2010 08:05AM

I have a problem with my new RAM, i gues thats where the problem is. When i install the new RAM 2x2GB Crucial DDR2 6400, i dont get a beep sound when booting the pc, and get the "error" message on my screen, power saving modus. When changing out with the old RAM or just ONE of the 2 new RAM the pc boots, but not with both of them. Have tried to test them each and pc boots with both apart from each other but not together. How can i get it to work with both together? MB: Asus M2N-X CPU: AMD Athlon 64 x2 4200+ 2.21GHz V.Card: Nvidia GeForce 8500GT HDD: Maxtor 120GB DVD burner Old RAM: 2x 1GB PC2-5300 GEIL Havent OC'ed anything on the pc aswell. Tim - Mar 23, 2010 09:56AM This may better explain my problem and how I messed it up. It had a lot of dust in it. I blew it out with a hair dryer on cool setting. I did remove the fan to clean it but did not un plug it. I used a Q-tip to get dust off the M-board. Now when I plug it in it looks as though it is starting to boot up seeing the green led's for the CD and DVD player but the fans kept gaining speed to where it sounds like it is going to take off. It does not seem to see the key board or the monitor. Have maybe I unconnected something or caused static that would cause this. Thx Tim Ambucias - Mar 23, 2010 11:13AM Hello, You have posted your question in a thread where the problem was solved. Should you wish to attract attention of experts to resolve the issue, I strongly suggest that you start a brand new thread. Good luck Gamer - Apr 12, 2010 05:54PM Hey Priisa did you look at your computer manual to make sure that your ram is in the right slots. for instance slot 1 and slot 3 will match on some computers while slot 1 and two will match on others. Cause if you put two different types of ram in or different mhz of ram it will not work. Shirley K - Apr 14, 2010 11:24PM Hi DJ AKSHAY You have some awesome advice here, I tried everything you have suggested and still I am not getting any response from monitor, keyboard, or mouse. PS and CPU fans both work, I unplugged Harddrive and DVD Drive, when I first press the power button the

keyboard lights flash and then stop, I get no light on my mouse, the monitor does absolutely nothing, my power light on the tower is messed up since I installed the motherboard over a year ago (not too worried they are only lights....right??). What I am wondering is ..... 1) When I try the cpu motherboard test with the memory removed I get three beeps and then nothing, could you tell me what that means please? 2) I tested a different memory strip and it didn't make any difference. I was wondering if I can swap the ram ..... initially using 2 - 512mb DDR PC3200 NONECC DIMM, removed both of them and tried 1-512mb DDR PC3200/400 strip, does not say anything about NONECC, does that matter, and also can I try and/or use say PC2700 or PC 2100 strips? 3) Any other suggestions on how to get this baby up and running again would be appreciated. I am handicapped and unable to afford a new computer so I am really hoping this one is not heading to the junk DJ AKSHAY - Apr 15, 2010 09:41PM Hi Shirley, yes, you can use any memory you've mentioned up here. The three beeps you've mentioned should be repeated as long as you leave the PC on without the memory card. Remove all PCI cards such as modem, Sound Card, WIFI Card etc... Do the processor heat test, remove the cpu fan then turn on the PC, you should feel the processor heating up, NOTE: You should not perform this test for more than 5-7 Seconds without the Fan on it. If the processor heat test is successful, reset the BIOS through the use of the RESET Jumpers OR disconnect the Power Cord from the Power Supply then remove the CMOS BATTERY and press the Power Button. Remember not to plug in the power cord. After this, put back the CMOS Battery in its place and reconnect the Power Cord and put back 1 memory card which you believe or you know is good. Inform me if you have further problems. Thanks... Shirley K - Apr 16, 2010 02:29PM Hi DJ Thank you for responding so quickly. I am only getting three beeps after I remove the memory cards, I wait for a few minutes after the last beep, but it doesn't beep again, I have tried it a number of times and always the same thing.

I did the processor test and my processor heats up immediately. I have reset the BIOS by removing the Battery, I did it twice as the first time I just waited for over 10 minutes and put it back in, but I did not push the power button, so I did it again. I had the power cord removed. I have removed and unplugged everything except the power from the PS to the motherboard and the front panel wires, and the CPU fan. I have tried a number of different memory cards and in different slots as I have 4 slots (2 blue and 2 black) I understand that the two blue are in sequence and the 2 black are in sequence, so I also tried sets of memory (as they were only 256 MB strips) first I tried the blue which is the first bank set, and then I tried the black) nothing I do seems to make any difference. I did notice when I power on it starts off sounding like it is going to start up for a minute or so, and then the fan noise slows a tiny bit. I have read somewhere that just because the fan lights up and spins doesn't necessarily mean the PS is working properly.....what do you know or think about that idea? I did test some of the volt producing pins on the PS and they seemed within the approved tolerance so I stopped testing as I also read somewhere that you shouldn't power up the PS by shorting the pins for too long as it can wreck the PS.....OH WHAT TO DO???? Unfortunately the spare PS's I do have are only 20 pin and my MOBO is 24 pin. I put in a new PS a year ago when I first built the system, but that went on me a couple months ago, so I am using one from out of a different computer. My MOBO came out of a fairly new system that was left out in the cold and the person turned it on without letting it warm and he blew the PS as that is all I changed and then it worked great for quite awhile, although it has been slowing down a bit before it quit.....I was going to reformat as I thought I picked up a virus, but I have the HD unplugged so that is not the (that would be toooo easy). Do you have any other suggestions? Thank you again for your help. DJ AKSHAY - Apr 17, 2010 06:23AM Hi Shirley, From the results you've got, I would advise you to replace the motherboard with a new one as the one you have is faulty.

One would need hands on access to the computer. It could be the power supply the motherboard takes different voltages than the fans. The fans on proves nothing about the power supply. If you can't swap out the power supply (my first option) then Take it to a repair shop.

Anyways, on to my problem: I've assembled the PC as best I could, It is complete as follows: Foxconn 400m01-g-6l motherboard AMD Athlon 5th Gen processor (not sure of specific specs, but it came preinstalled with the MB) Harddrive that I've checked and it works (by plugging into another computer...Windows may be corrupt?) Floppy Disk Drive which isn't connected CD Drives (2) that I'm positive aren't the root of the problem, from testing. 512 Kingston DDR(1?) memory

ATI graphics card Power supply Ok, here's the symptoms: *On Power On* -fans spin at regular speed, do not stop until I shut it off -power light in front comes on, stays on, no flickering -the other, red, light in front that flickers with activity (sorry, forgot the name) does not come on, but this is an older comp and it may be just out -As I said earlier, HD works fine for access, windows possibly corrupt? -when plugged into a screen, shows NOTHING on the screen (goes orange, but does not run self-diagnostic like it does when not plugged into anything) *-----*tried plugging directly into MB and into Graphics Card, same result -when speakers are plugged in, they click once when it starts up (like normal) but no windows theme plays afterwards I'm thinking it's Windows' fault, but I'm hoping someone could find something else I'm missing? I also did the bit with an eraser on the memory stick, didn't help. I switched everything onto another motherboard and still had the same result, no image/no sounds. Like windows won't boot. infusion - Apr 21, 2009 02:20AM hello friend..i had also the same problem some days back.u just unplug all the cable from cpu and hold the power button for 1 minute and again plug all the cables.if it won't work then swap the RAM into next slot and clean the dusts if any near the clips.i hope it will work.... admiralspark - Apr 21, 2009 09:50AM Tried both, no success.

CityITSpec - Dec 24, 2009 10:57AM I feel it's important to note that this is a completely invalid comment (MB Infested with Viruses). MotherBoards, mainboards if you prefer, do not get viruses! Viruses are

software...MBs are hardware...there is a seperation. Also, as a private client of a friend just stated: "Wow, the inside was really dusty! No wonder I got so many viruses!" NO! They are seperate...dust is bad, but only because it insolates and allows thermal buildup. It does not cause viruses. I'm sure this issue is solved by now, did sound like MB...but I just wanted to note that this guys MB was not infested with viruses. - CityITSpec AnsonAS - Mar 3, 2010 03:07AM Who said de..... hardware cant infect by virus???? what i know is can de..... the virus effect for coding... jake › admiralspark - Sep 8, 2009 05:46PM hi everyone, I have every symptoms as stated above except my pc boots and starts for not even a minute then black out but the power, fans and lights on the motherboard still on...what could be the problem; i have used erasor and also have bought a new RAM...but still doesn't work.. help pls... Jake Adam - Dec 8, 2009 07:34PM If the monitor goes black then it may be your video card or integrated video might be bad. Put a new video card in and check. They are pretty inexpensive. Note what type of card slot you gave to make sure you get the right card. PCI or AGP port. Good luck MAC IS the answer › admiralspark - Feb 17, 2010 09:06AM When power is off (pull power completely out of wall). Watch and make sure you green indicator light is off on your motherboard.

I have learned a lot from your posts and am glad you are so attentive to respond to everyone. I read a bit back in the post about someone having a similar problem with an ASUS P5N motherboard but couldn't find the outcome. My motherboard is an ASUS P5N-E SLI . It has been a wonderful motherboard. Today, with no warning, while trying to turn on the computer: no video output, no beeps, all fans are on, no startup. So, I removed my video card, audio card, memory, and extra case fan. Still no beeps. Motherboard LED is lit, hard drives are working, dvd drive is working. I assume it's not the PSU. Now, according to you, it's either the motherboard or the CPU. I have a large heatsink on my CPU, no fan. This allows me to feel the metal on the heatsink right on top of the CPU and it does not get warm when I turn it on. So, this means the CPU is bad, right? But, is it not possible that damage to the motherboard is preventing power from reaching the CPU? Let me know, please. Then I can decide whether to buy a new CPU or a new Motherboard. Oh, I haven't tried replacing the battery on the motherboard. Can this still be a possible problem? Thank you for your help.

ANSWER +14 New Guy Jun 22, 2009 08:57PM

Hey, I just had the problem as well, not sure what happened......I came home from work, turned on the comp, looked fine, went to jump in the shower, came back and it seemed my comp was stuck in hibernation, so i turned it off, and got the same problem. The lights would come on, all the fans would start running, but it would stay black on my monitor and I heard no beeps/boot. I got on another comp in the house and started forum searching and halfway found my answer..... Now this problably has been said already, but I havent had the time to read through all the posts, but it turns out that when I removed my PCIe video card, and plugged my monitor up to the onboard card on my mobo, the computer started up fine! So I cleaned the PCIe card and tried to put it back in and start up the comp again, only to have the black screen, no boot thing happen again, but this time I noticed the fan on the card was trying to spin, but couldnt, kept getting stuck. Tried cleaning it more to no avail... So my conclusion is either the card/fan itself is dead, or my PCIe slot on my mobo is dead, but w/o it in the slot my computer runs just like it did, I'll have to find out the issue when I have more time. Hope this helps

However when I unplug keyboard and mouse from USB slots and plug them back in, PC continues start-up fine.... Any suggestions?

DJ AKSHAY - Feb 5, 2009 09:54AM

It can be that either your mouse or your keyboard is faulting. try unplugging one of the two before starting your PC and power it up to check with which one it gets stuck. Then you will find out which one is faulty and you can then replace the defective input device. Gamer - Apr 12, 2010 05:38PM Yeah one of your usb ports may be bad, or grounded out. Your mother board can not tell which one so it assumes their all bad. You would usually get a over run error though. do you get an error? Gamer - Apr 12, 2010 05:44PM after you get the computer back on turn up your sound. First unplug all your usb cables, and thanstart pluggin in one usb port at a time. You should know the noise it makes when you plug it in, if one dont make a noise at all than that usb does not work. I had the same problem. Flashing the bios or maybe just taking out the cmos battery and putting it back in might fix it.

ANSWER +5 omar232 Dec 23, 2009 01:34PM hey guys i need urgent help please. I was browsing the net when a blue screen error came up on my screen and i had to restart my laptop. while restarting it got stuck somewhere in the boot process. i left it for 15 min nothing happened so i turned it off and tried to turn it back on but now the screen is blank and doesn't turn on, but the fans

turn on and the lights on the keyboard turn on. I've tried plugging it to another external screen to see if the problem is from the screen but it shows no signal. so i believe the screen must be okay. how can i solve this problem? i have HP pavilion laptop, any help would be appreciated! thanks in advance!

ANSWER +4 shockme Feb 8, 2009 07:55PM Here is my situation. I have a HP Pavillion 1473w. Recently I went to use it and the mouse wasn't working. I thought the batteries but noticed the reciever lights were not on. I shut it down and it wouldn't come back up. I get a black screen. The fans come on and I hear the dvd drive and can open the drive. The motherboard is an ECS RC410-M. Other things that I have checked Monitor works on another computer so I ruled out the cable and monitor (swapped cables also) I tried resetting the bios via hp recommendation of remove power cable and holding button in for 5 seconds. I also tried removing the power cord, moving the jumper over, pressed the button 2-3 times, move the jumper back and no change. I've removed the modem card which was not in use and tried adding a working video card. No change. Everything is built in so there are no cards hook in right now. I removed the cpu fan and started it for a couple of seconds and felt the cpu heating. I jumped the 24 pin connector on the board and the powersupply fan worked. Also the light on the power supply is on. I tested the 4 pin motherboard connector, all the molex connector and jumped the 24 pin connector and tested all except black, gray don't recall a brown using a voltmeter and everything was reading at 3.3, 5 or 12 I have 2 memory cards both were swapped, used individually in both, and I used an eraser on the gold pins, no change. I removed the memory cards and powered on but didn't hear any beeps. I see the

speaker on the board and assume it is working. I have also removed the battery and tested it on a voltmeter to see that it worked. I believe the reading was around 3 My guess is the board is bad. One bit of info that I don't understand is the switch on the front of the case is a circle and it turns blue, there is also a orange light. When I push in the switch the light flashes blue but then goes out. I believe normally it would turn blue and stay on until you shut off the pc. I'm not 100% sure that it worked like that normally but am pretty sure. I ask as I don't know if that could indicate anything or if a faulty switch could cause problems like mine. If the board is the problem, I had planned on ordering the ECS RC410-M board online since it was the same board. Am I correct that since the board is the same that I shouldn't have any issue with booting up? There isn't a windows xp disc but I have the 2 dvds that were burned when I bought the pc new. Any ideas or other things I should test for? I don't want to order a board is that is not the problem.

ANSWER +4 Dredger Aug 31, 2009 06:01PM So I tried DJ's advice of removing all the RAM and turning on the PC.

If it posted and started to load I cleaned and added another stick. In the end all 8GBs of ram worked fine I just needed to clean them up.

+3 Trent323 Mar 17, 2009 07:36AM 1. My computer froze. so i restart. 2. It would power on, but would not boot. (no signal to monitors.) 3. I checked all cables, followed all your steps. 4. When i moved the RAM around it loaded up normal again. (long beep with no RAM.. yay!) 5. After about 10 min it crashed again. 6. I moved the RAM again and it loaded again. 7. After about 10 min i get blue screen. 8. I have tried moving the Memory over and over, but i cannot get it to boot up like it did in steps 4 and 6. I was hopeing for a suggestion from you DJ ASKSHAY. I have two RAM cards and neither work in any slot now. (i only have 2 slots) Should i buy a new memory card?

DJ AKSHAY - Mar 17, 2009 08:08AM Yeah, I believe you have not tried the eraser tip yet. Try it and let me know, if the memory card works then ok but remember that you will need to change it/ both in the future. ANSWER +3 lukc Jul 29, 2009 04:49PM Hi guys, I reall need your help I spilled some juice over my laptop and now it has some problems. At first it didn't boot up, only the fan and power on diodes were working and it was beeping constantly, constant middle long beeps. The screen was blank. I tought that the motherboard is dead, but after a few days it started to work normally! It worked then for about an hour but now it has again the same problem. I tried many of here mentioned things but none of them helped. What also seems weird to me is that it only beeps when the RAM is pluged on, if I take it out of the socket it doesn't beep !! I didn't tried to reset the bios yet and do not really know if it can help. Because it started to work once before I assume that none of the crucial parts is really

damaged. Any idea what should I do ?? I would appriciate any suggestion, cos I really need my computer. thanks in advance!

ANSWER +3 Spartacus Oct 3, 2009 08:40PM Thank you so much for all the excellent options that you provided in your responses in this thread. I tried almost all the methods that you mentioned including using the eraser method on my memory modules but to no avail. I was about to go out and buy a new motherboard but then I thought of using the eraser method on the GPU pins and voila, everything is back the way it is supposed to be. Thanks again!!

ANSWER +3 Braiden Oct 24, 2009 07:58PM Well my problem is that one night we had a power outage while I was sleeping, when the power was restored I tried to reboot the PC but after all the lights came back on there was no nothing coming up on the monitor at all except a quick flash of the prior image. Please tell me this is fixable and easy to do my self? Thanks

ANSWER +2 arnold Dec 25, 2008 10:35PM my computer is not booting up..the power is power on mouse, and also in keyboard...the motherboard is also working fine..what should i do..please help to save my machine..

Meatbag - Dec 26, 2008 11:49PM I just got new RAM for my Compaq pc, The Ram is not working and when i turn the pc on with the new cards in, i got the exact thing you explained. I was able to put the old ones in and it works again but that sounds like the problem. The cards are very static sensitive so you have to ground the pc casing before you touch them, but maybe your card(s) became loose. If someone knows what they're doing this can be easily checked. Good luck DJ AKSHAY - Jan 13, 2009 11:55PM The problem that you are getting with the new RAM is that your motherboard does not support the frequency of the new memory cards you have purchased. Check the frequency mentioned on your memory card with that supported by the motherboard (Or with the old ones' frequency). You'll find the supported frequencies of memory cards for your motherboard in the motherboard's manual or on the it's website. Sonic - Jan 15, 2009 10:22AM So if I take out my ram cards, then turn on my computer I should hear some beeps? I have been having the same problems as above. Even with the ram cards out, I turn on my computer an no beeps at all. Does this mean I need a new motherboard? I did recently upgrade my power supply from 350 to 500 and at the same time got a new video card. Everything worked great for a couple days and now this related problem. Thank you for your time. DJ AKSHAY - Jan 15, 2009 10:36AM Have you performed the processor test as mentioned above? If the processor is good then you need to replace your motherboard with a new one. One more thing which you can do, there's a jumper to reset CMOS / BIOS settings. You'll find it usually near the CMOS Battery. Turn off the pc. The jumper covers only 2 pins at a time on a total of 3 pins. NOTE ITS ORIGINAL POSITION BECAUSE YOU WILL HAVE TO PUT IT BACK THE SAME WAY IT WAS ORIGINALLY. change its position to cover the middle and the pin at the other end which was not covered. REMOVE your power cord. then press your power switch on the CPU 2 to 3 times... Then replug the power cord and ensure that you have placed your memory card and vga card properly for normal use. If this works then no need to change the motherboard, cheer up dude... chairator - Oct 29, 2009 03:52AM

Hi, I have a problem with my computer as well. Last night everything was fine, but this morning when I switched it on, it just woudln`t boot. It shows a message " Windows failed to start. A recent change in the hardware or the software is causing the problem". However, I haven`t made any changes in the hardware nor the software. Then it tells me to reinstall the windows, I put the CD in, but no reaction. When I press Enter it takes me to another screen and it tells me that my register is missing or corrupted. I really cannot understand how this happened when it`s been working fine. What can I do about it? Can you please help me? Thanks Jemah › DJ AKSHAY - Mar 12, 2009 11:02AM HEY DJ I just a horrible problem. I decided to reformat my pc. And after Install all my drivers I restart my pc and the monitor is not working. I have a m2n sli deluxe asus motherboard. I tried removing the batter and doing the jumpers to clear the bios but nothing worked. Everything works fine the mouse and keyboard all get power but my monitor doesnt. I think it might be because when i installed my drivers i didnt restart them individually, and just loaded them all up then restarted. Also I only hear one beep when it starts up. Is there any way I can fix this? Kind of hard because I cant do anything without seeing anything on the monitor. PLEASE HELP ME THX! DJ AKSHAY - Mar 12, 2009 12:24PM Hi dear, you are having a problem with the graphics card which I believe is not integrated on the motherboard... Try removing it and remove static energy on the gold plated part which goes in the slot. Otherwise if this does not work then you need to change the graphics card. DSQUARED - Mar 24, 2009 06:45AM When you push the power button, all the lights come on, some stay on, and the hard drive powers up, but there are no post beeps and the screen never does anything. I thought the power supply might be bad, so I bought a new one. Didnt fix it. I thought the hard drive might be bad. I bought a brand new one. Nothing. Any and all suggestions would be greatly appreciated.

Alagappan - Jan 23, 2009 12:40PM Hello guys, I have a old comp running XP. After booting up it passes the bios gets struck there in the next screen. I replaced the RAM in another slot same result. Cut off the power to cd rom just the HDD same result. Tried with another HDD no luck. So in the BIOS i changed to be more verbulous and booted it. Its trying to find c: Tried replacing the cables, another working HDD, tried using live cds nothing thing is that it detects everyting at bios and nothing in the next screen Any other suggestions Regards, Alagappan DJ AKSHAY - Jan 24, 2009 01:50AM Reset the BIOS of your motherboard by following my instructions already posted above. After changing the hard disk with a new one, you should notice this message:

INSERT BOOT DEVICE... Did you replace with a new one or another old one? If its old, it will still be stuck in that step because if there is a windows having different drivers than those of your motherboard, it will never load the windows. Martin - Jan 27, 2009 02:30PM Hi there I am experiencing something similar with my three years old computer. It suddenly stopped working (its a dell dimension 4700). When I press the prower-on button the normally green light just flashes orange. Just after pressing the the power-on button the fans turns a few turns and then stops. I have tested shortcutting the green pin with one of the black pins and then nothing at all happens, not even the fans turns the slightest. Removing the RAM changees nothing (no beeping sounds) and using the rubber to remove the static electricity does not help either. What might be wrong here? I first thought it might the the power supply, but the fans actually turns a little bit before stopping... I have not changed the CMOS battery yet, but will do so tomorrow. Could it be the motherboard or is the power supply still more likely?? Any help appreciated. /Martin DJ AKSHAY - Jan 28, 2009 02:33AM You need to repair the power supply my dear. When shorting the 2 wires green and black, the fan of the power supply should keep turning because the power supply should remain ON as long as you short the 2 wires. saturnrocks - Jan 28, 2009 04:57AM Hai MR.DJ Akshay, your suggestions helped me lot.My mail ID is [email protected] If u dont mind can u send your mail ID. Thanking you. Martin › DJ AKSHAY - Jan 28, 2009 08:22AM Thank you for the fast respones. By repair, do you really mean repair? If so could you point me towards some information on how to repair the power supply. I am just gonna order a new one if it is tricky (and dangerous) to fix it myself.

Once again thank you for the help. DJ AKSHAY - Jan 28, 2009 09:11AM Well, if you can get another identical power supply easily, then you should buy one and replace the defective one. Here in Mauritius, there are so many representatives of DELL but none of them can supply us with spare parts such as power supply because these are PURE Power Supply and not ordinary type, that is they last much longer than the ordinary ones. Repairing must be done by qualified technicians or repair centers. I would prefer that you buy a new one rather than repairing it. Popinjay - Jan 31, 2009 08:16PM Hi, I tried your advice. Took out the RAM, no beeping. Did the processor test. did not get warm. I have a gigabyte WP45-UD3P motherboard, the phase leds are on during boot up but do not turn off. The power leds on the mobo do not light up. Clearly it is a processor problem but is it also a mobo problem? DJ AKSHAY - Jan 31, 2009 11:06PM Make the power supply test as stated in my posts above. It could be that your power supply is defective, are the CPU fans and any other fan turning? Do you hear your hard disk spinning sound? Are your CD ROM drive working (Press the eject button). noodles - Feb 4, 2009 12:01PM Hello, DJ, thank you very much for all your advice above. I am having similiar problems. The image on the monitor suddenly froze up, keyboard failed but there were still orange lights it. I then switched the computer off by pressing the restart button on the front. The monitor screen now had no image (complete black) and the light at the front has turned from green to orange; now no lights on the keyboard. Both fans inside the computers were working and running quietly. I couldn't hear any spinning noise inside the Hard Drive. I have preformed the motherboard test and there were no beeps, I have also done the processor test, it wouldn't heat up. I have rubbed the RAM card with eraser but it didn't help either. When I pressed the adjust button on the front of the monitor, it says ' In Power Safe Mode. Press computer power button or any key on keyboard or move mouse'. I 've tried those but nothing happened. Please help. noodles › DJ AKSHAY - Feb 4, 2009 12:22PM Sorry DJ, forgot to mention, the computer had been running extra slowly for the last three days before it crashed. DJ AKSHAY - Feb 5, 2009 09:49AM Have you tried to reset the BIOS settings using the jumper reset settings. See my posts above. Is your internal speaker working? Not to discourage you dear, I suspect a processor failure. Because if your processor does

not heat up then I am very sure that the fault lies with the processor and given that your system was slowing down. Normally even if a motherboard is faulty, the processor should heat up but if the processor itself is not good then you will get no beep sound, I believe that your motherboard is still good. badladdad › DJ AKSHAY - Jul 10, 2009 08:00AM my mother in law has a gate way and she was waiting on a game to load and the computer got stuck so i pushed the power button and would not turn off so i unplugged it waited and then plugged it back in and as soon as i plug it in the fans come on but i dont hear hard drive and the cdrom wont open i even unplugged the power switch wire from mobo still the fan s come on when plugged back in no monitor nothing but fans running please help thanks badladdad Alagappan › DJ AKSHAY - Feb 4, 2009 01:41PM yeah i resetted the bios. still the same result. Even when i try with another HDD i still get the same message Insert boot device. Regards, Alagappan DJ AKSHAY - Feb 5, 2009 09:57AM Ya in fact you will be getting same message. when you insert another hard disk, you need to install a fresh copy of windows. Only then will it boot. First is that you must check in Bios if is detecting the hard disks. doitonline - Feb 11, 2009 03:41PM Hey DJ, i have a problem with my friends laptop Acer aspire, it does not boot up and it restarts itself when ever reaches the blue screen (windows welcome page)..

We want to put new windows as the current is arabic version and we need to go with english version this time.. i know control pannel can change language settings but the lpto does not start up, any help>? Thank you. DJ AKSHAY - Feb 12, 2009 12:16AM Perform a fresh installation. Enter BIOS, then put the first boot device : CD/DVD-DRIVE Save and exit BIOS. Your system will restart, insert the Windows installation disk.

It will tell you: Press any key to boot from CD..... Press any key and it will load all the files. Then you will have to follow the on-screen instructions to format and install the Windows. As simple as that.. t - May 2, 2010 07:47AM If this does not work and the black screen comes up error in loading operating system (XP) what do I do? mckchris03 - Oct 15, 2012 06:01PM try thr cmso battery ANSWER +2 dafoo21 Feb 7, 2009 07:08PM Hi DJ, I just put my system together.

ANSWER +2 Gold Texture Mar 6, 2009 09:27AM So DJakshay, I need to reset the BIOS with the jumper? Just taking out the battery won't do it?

DJ AKSHAY - Mar 7, 2009 10:55AM Yes, you can proceed by doing this also but some models do not reset by simply removing the battery. The best way is reset it through the jumper. Steven - Mar 29, 2009 04:14PM Hi mate, Here is my problem: Motherboard powers up but I have a no signal on my display. Have tried display on other computer and works fine. Have unplugged all cards, ide, sata, etc and removed RAM. I get the continous beeping. Have also tried a new psu and problem still happens.

When I put the memory modules back in it will still not boot but I hear no beeping. Have tried CMOS resets and all other tests - CPU does heat up. Do you think I need new memory modules? have tried swapping and erasing. Motherboard is ASUS P5B TMX/S.
