PC Won't Post or Boot

Q: PC Won't Post or Boot

When I press the power button, fans start then immediately stop, then start again, etc. Disconnected all peripherals but monitor, removed memory stick. No signal to monitor. When connected, hard drive starts then stops in time with the fans. It seems the PS is cycling on and off continuously.

Preferred Solution: PC Won't Post or Boot

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


I am having the one of the worst pc problem i have faced.....
It all started with my pc restarting(it was a power failure) to show boot device failure, insert system disk, i tried everything, from unplugging usb devices to re inserting sata cables but to no avail, now when i try to reinstall windows the setup recognizes all my partitions but refuses to install into any of them, ubuntu only recognizes one of my hard disk and partition( i have 1 big 500 g hdd as 1 part, and 2 250 g hdds in raid 0). I tried booting from my bart pe created windows live cds but they dont detect any partitions what so ever, windows 7 dvd's repair utility can access my file structure when i browse for drivers, but it wont repair the problem, nor will it install.
Please Help!

I am having problems with direct booting into Windows 8 installed into a VHDX file.
This is a four-partition UEFI boot on a GPT drive. EFI files are residing on a second partition of disk 0 (the ESP partition) in the EFI folder. The boot virtual disk is residing on the fourth partition of that disk 0.
When I turn on the PC, it shows black screen after the BIOS POST screen. No Windows 8 boot menu, no other information is displayed. However, if I press Shift+F12 (or F12) to start Dell BIOS Boot Menu and choose Windows Boot Manager from the UEFI part of
the boot menu, Windows 8 starts to boot without difficulties.
How do I make Windows to boot automatically without having to select Windows Boot Manager in DELL BIOS boot menu?
I believe I messed up with boot sector somehow... What needs to be fixed provided that Windows 8 will boot into VHDX file?
Thank you.

Well this is the world we live in And these are the hands we're given...

Sorry first time poster. I wasn't too sure whether to post to the Windows forums or hardware forums. From what I can see, this seems like a hardware issue of some sort.

The problem I have is that during bootup my PC goes through all the normal things. It detects my CPU, detects RAM etc. gives me nice BIOS Post messages that appear normal and then goes to a black screen. It will then sit there for 50 seconds (i've timed this twice) and then proceed to go to the windows XP startup screen (which takes about another 10-20 seconds to load up windows).

I've attempted to log the bootups by using the Windows Boot logger (by pressing F8 before windows boots). The ntbtlog.txt file isn't very descriptive, and only lists that a whole lot of drivers have been loaded, and some that haven't (it doesn't list any errors).

I've also tried using BootVis to analyse the bootup. I found this a little hard to decode the information it gave me, but there doesn't seem to be anything untoward happening.
The last boot logger I tried was bootLog XP (by greatis software). According to bootlog XP, windows is only taking 19 seconds to load up.

Can anyone suggest any other ways to analyse the boot sequence and discover where my computer is stalling?

(specs are below.)

Thanks in advance,


CPU: AMD Sempron 3000+ Socket 754 (unsure whether it is Paris or Palermo core)
MBoard: Foxconn NF4K8AB-RS

Hello all,
Maybe someone could help me with a problem that I am having.
I am running a Tbird 700 on a Epox EP-8KTA motherboard w/ VIA KT133 AGPset. I have 256mb of ram and a 15 gig hd and an ATI EXPERT2000 AGP 32mb video card. I was playing Pool of Radiance for a few hours and then saved and stopped. About 5 and 1/2 hours later, I checked the weather online (dsl) and then closed everything down to the desktop. Which is where I usually leave the computer, running with only windows desktop up and no programs running. Roughly 1 hour later I came back to the desktop to find that it had hung about a 1/2 earlier (the clock was stuck at the hang time). I tried to reset and nothing. I tried turning off the computer at the switch in the back and nothing.
I tried:
-switching out the ram
-disconnecting everything but the ram, hd, floppy, video card
-disconnecting everything but the ram, hd, video card
-reseating everything
-clearing the CMOS
-including doing it by removing the CMOS battery
and none of these things worked in rebooting the computer.
With everything connected I can turn it on and the cpu fan starts and the cdrw led pops on and then off, the cdrom led stays on,
the hd led stays on, the floppy doesn't run at all, the monitor sits in standby mode with its led flashing, and the computer won't even post. I would normally start to try and figure out if I burned something out, but this has happened two other times. Both times I shipped my computer back to the supplier a... Read more

A:Won't Boot or Post

Hi rowayn

Try disconnecting everything but the ram, video card, memory, and CPU and see if you can get the POST showing up on the CRT. If so you can add the removed items back one by one.

Are the hard drive and cdrom on the same cable? The lights shouldn't be staying on.

I am having trouble with a system running WinXP Pro. It has an Asus mobo, AMD 2500 CPU, 512MB DDR 400 RAM, an FX5500 video card, separate DVD and CD burners, and an 80G Western Digital HD. Everything has been running well for the most part for almost a year. Now I cannot get the system to even post.

When the power switch is turned on, the CPU fan goes on briefly and then stops. Nothing else happens after that. The green light on the motherboard goes on and stays on. The case wires are connected properly. I tried swapping power supplies but that made no difference. I then swapped the RAM, and got nothing, then changed the motherboard. When I powered up after replacing the motherboard, the CPU fan remained on for about 8-10 seconds longer, but other than that there were no changes. If I clear the CMOS and then try to boot/post, the CPU fan stays on for a good 15-20 seconds, and then when I hit the power button again I get nothing, unless I clear the CMOS. It still will not post though.

Could the CPU be causing this kind of activity (or absence of it)? I don't have another CPU to swap out and I don't want to go buy another one unless I am certain that could be the problem.

Any insight and help on this would be greatly appreciated.

I've been having a few different problems with my computer recently. Having 3 different problems at once has made it hard to deduce the source of my major problem, being the computer no longer booting. First off, I've had some adware problems, which I dont beleive is related to my problem at all. Secondly, some textures in World of Warcraft have been displaying funny.But it didn't seem it was only the textures, whole portions of the User Interface where displaying funny. At first I thought the game files were corrupt, so I error checked game files and it found no errors.

So later that night I had to restart my computer after installing some anti-adware software to get rid of my "windowsclick" problem, and the computer would turn back on after the restart but wouldnt post or display anything to monitor. Similar to a recent problem I've had when I fried my vid card. Since I didn't have a spare vid card I checked to see if a RAM module was bad since I was getting these weird random computer restarts recently. After messing around with the ram switching out sticks in different sockets the computer actually started back up.

Thinking things were "normal" again I reinstalled my favorite video game to find the graphics doing the exact same thing as before. So I decided to try reinstalling video drivers. After installing the ATI 3600 driver from the site it required a restart. Upon restarting the omputer it did the exact same thing as bef... Read more

Hi all

I recently built a gaming rig and collected it yesterday. However, I have problems getting my rig to POST. Whenever I hit the power button, many times it would just hang there without any POST aka "beep" sound.

Only after numerous attempts turning on and off the power switch can I finally get the comp to POST and then boot up the OS.

Any suggestions would be greatly appreciated.

A:My will not boot/post/do anything at all...

Your system is DOA (bad mainboard).  If you purchased direct from Dell, you can return it for replacement within 21 days after it shipped to you.  Call Dell to start that process (DO NOT depend on email or chat).  
If you purchased through a retailer or independent third party, contact them for replacement of the system.

I just got an MSI K8N Neo4 S939 mobo with an AMD Athon64 4000+.
Put it together with my previously owned PC parts and it won't start. The hard drives don't spin, nothing but the CPU fan. I took all the accessories out (drives, cards, ram). And still the same. The monitor doesn't get a signal.
Also, maybe important... when I turn on the PSU, the CPU fan turns on. I have to press and hold the case power switch for a short time to get the "system" (fan) to turn off.

I've got an old HP Pavilion 4455 that I got from work for my kids to use. It's 400 Mhz, win98se, 192MB ram. Was running perfectly fine one evening. Shut it down that night, turned it on the next day, and it won't boot. No post, no beeping of any kind. Everything 'appears' to power up. Hard drive is starting, processor fan is going, cd rom light comes on, and I can open the cd rom, and the fan in the power supply is running. Can't boot from a floppy, as it seems to not get to that point in the boot sequence. I have noticed that while everything does seem to be getting power, the floppy light does not come on at all.
I downloaded the pdf for the motherboard in this machine, so I could try re-setting the bios. But, the really strange thing is that where the diagram says it is, there isn't anything in that location on this board. So, I took the battery out for 20 minutes, and then replaced it with a new one. Same thing happens.
Anyone have any more thoughts or is the machine just dead?? (and good for minimal parts)

I just recently picked up a used XPS 630 which has been running fine up until recently. About two weeks after I got it it had a random hard drive crash which turned out to be a SMART failure having something to do with the read head in the HD going bad. I replaced the defective hard drive with a brand new Dell unit, performed a system restore from the image on the replacement HD and then installed Windows 7. Over the next two days I loaded the PC back up with all the stuff that I lost due to the bad HD (thank god for back-ups). Then, randomly, I try to switch on the computer and it won't POST. 
When I hit the power button the LED's come on, the power button is illuminated, and I can hear the case and video card fans spin up, but I nothing happens on either monitor. Is my MB or video card toast?
Any and all advice is welcome. The PC still has almost 2 years of warranty through Dell, but I'd much rather try and fix this myself first since calling tech support isn't the world most fun thing to do.
Also, all drivers, BIOS and firmware has been updated from Dell's site with the exception of the ATI drivers which are from ATI. 
System specs listed below....
XPS 630, 650i SLI MB, Core 2 E8500 @ 3.16 GHz, 4 GB RAM PC2-6400, Radeon 5850 HD graphics card, 750 GB Seagate Primary Drive, 160 GB Seagate backup drive, Sound Blaster X-Fi sound card, Ralink Wireless G PCI card.

A:XPS 630 will not Boot/POST

More info...
Power supply LED is solid green.
Attempted to unplug the unit and hold the power button for 30 seconds to drain any left over power...plugged it back in, same result. No POST.
I can hear the hard drive initialize, and the DVD-ROM spin up in addition to all the fans and lights coming on. 
I'm thoroughly stumped...

Hi all,

Gigabyte GA-X38-DQ6 Motherboard
Intel Q6600 processor

Everything was working fine up until a few days ago. I rebooted to complete a software installation, and after the system POSTs, it does nothing. Literally, nothing. Black screen, no cursor. But it DOES POST. (I feel the need to reiterate that since on other forums people overlook that detail).

I cannot boot into Safe Mode because the system doesn't even get that far. Immediately after POSTing I get the black screen. At this point I have replaced the motherboard, thinking that was the problem, but the result is identical. I have replaced the power supply, since the system DOES POST but can't boot from any HDD, CD/DVD, or USB drive (all give the black screen as a result), but that hasn't fixed it either. It isn't my RAM, I've replaced that as well. It isn't my video card, I've tried booting with the onboard video which my brand new motherboard has, and get the same result. I've replaced all power cables, SATA cables, and even the power cable going from the PSU to the wall.

I'm at my wit's end and hoping you all can help me. It's an older computer that I need and can't replace at this time because we are financially strapped due to unfortunate circumstances. I have a Dell Inspiron 570 that started having issues a couple of weeks ago. I thought it was the monitor because everything went black. Switched out the monitor and it worked fine for a week. Then nothing. All fans are working. It seems like the computer wants to POST but it's not. You will see a flicker on the screen and then nothing. No words will come across the screen. No beeps other than when I remove all RAM (stating it has no RAM). I've looked all over and now hope you all can help me to troubleshoot this and get it to working again. I don't mind small investments, in fact I have a new motherboard (same one) sitting here ready to be installed if needed. Aside from that, I need to wait several months to get a new computer. HELP me please!

Hi,I'm trying to fix my cousin's computer and i am unable to boot the computer from a cd or usb device because when the computer starts up, it automatically goes to something like "enter hdd password". once u enter the password it goes straight to the windows bootloader. there is no POST or anything that allows me to choose how i want to start up. How can i remove this password? It goes straight to the bootloader after the password prompt comes up. There is nothing to do prior to this. How can i fix this? I need to be able to boot from cd and hopefully remove this hdd password! Also i cannot access bios due to the password prompt and the automatic windows bootloader that comes after. I am seeing no way to access bios whatsoever. However i can still boot into windows and surf the internetand etc, so if i can do anything from there please do advise.

I have checked SW1 all are off but 5 is on I couldn't see anyother jumpers besides the audio jumpers.
I tried resetting the cmos but I'm removing the battery now and going to leave it out for a couple of hours.a side from this I don't know whats wrong with this thing , unless the board is just crapped out. which might be possible.

all the board does is power on for 1 sec (if that) and then the fans quit with no time for post or error's I have also done this with no cpu installed.

Now i can't see any problems with the initial setup, no compatibility errors etc. Installed XP and on first boot-up it took approx 5 mins to get into XP. Disabled quiet boot, and it was taking a long time to POST, but i couldn't see any particular points that it took longer to get past. Went through the BIOS and disabled everything that wasn't needed, stopped error halting etc as i was using a USB mouse and keyboard. Still had the same issues. Also, at the same time i was having trouble graphics-wise, had a blue tinge to everything on one DVI port, and a cyan tinge on the other. Ignore this for now though, as i'll come back to this. I thought i'd try flashing the BIOS to see if this would solve it, but curiously, AsusUpdate listed the BIOS rev as one for completely different mainboard (I forget the model number, but it definitely wasn't correct). I eventually managed to flash the BIOS with the correct update, but this had no effect at all, still the same problems. At this point, i concluded it had to be the motherboard, so i sent it back. The supplier tested it and decided it was indeed faulty,... Read more

This issue only just started about a week ago. This only happens when I first boot up my ASUS K73SV laptop, it will run fine for about five minutes, but then it will gradually start to lock everything up, to where whatever programs I was using stop responding, then the taskbar is the next to go, and then anything else. The only thing I can do is move my cursor around as the blue wheel spins, and wait precisely five minutes until everything starts back up again. I was going to try a system restore, but the access points do not go far enough back. My computer is very frequently cleaned with CCLeaner, and I have avast! to help make sure nothing is infecting me. I've made sure I have no suspicious programs installed and everything. I am at a loss. I do not know what else is left to do.
After Budapest was unable to help me in my topic "Locking Up Issue", they referred me to this area to follow the instructions and make a post with my DDS log. Here it is as so.

A:Need Help! Non Boot, Stops @ end of POST

Most lockups at the POST indicate hardware issues.
When did the issue begin? Any new hardware added?
If yes then remove the hardware then boot up again.
If no then remove everything external that's plugged
into the computer [except for monitor, power] and
try booting.. if it still locks up then you're more than
likely looking at something internal. Try reseating
internal components etc.

Try searching the forums.. lotsa ppl have had this
issue before. You may find some helpful suggestions.

Hi Everyone,

Bit of a toughy here but hope you can help me out.

Went to turn my computer on this morning, everything seemed fine as I had been using it for hours the night before. Anyway what happened was the computer sounded like it turned on ok, but the screen wasn't working. The screen was in 'stand by' mode as in there was power to it but no actual signal.

So tried another, screen - same thing happened. Tried both these screens on different computers and they worked fine.

So did some research about computers and booting and came across the term 'POST'. From what I understand ALL computers will make a small beep when they boot which is known as POSTing - a basic indication that the boot sequence was successful or not.

My computer is not making any sounds or beeps on start-up. The floppy disk and CD drive will spin and light up but no beeps. So the question I beckon is:

1) Do ALL computers definitely POST (beep upon successful Boot)?
2) If your computer is not POSTing, where to then? I think it's a matter of replacing the motherboard.
3) Is DIY replacing a motherboard a big thing? If I can source the exact same motherboard and just to a simple switch - will that be ok?

Thanks everyone - any comments very appreciated.

I hope this is the right place for this topic. My son re-booted his computer yesterday and ever since, it'll go through the POST but when it comes time to boot into Windows, there's a beep and it's back to the start and POST.

He apparently hasn't installed anything lately or noticed anything unusual.

I tried sneaking into Safe Mode, but it won't boot into anything.

For what it's worth, the PC is less than a year old and it has XP on it.

Any ideas on where to go with this would be appreciated.

A:Computer does POST does not boot

If it is a new-ish computer you will hopefully have the manual for the motherboard? If not, find the make/model of the board and search for the user guide on the net.

The reason i suggest this is that the beep you are hearing is an error code. Different beeps mean different things, i.e. 2beeps might mean there is a problem with the graphics card etc... and the user guide for your motherboard will outline what the beeps mean.

Then you should be able to find out what the problem is, and come back here for how to fix it!

I'm trying to help a friend with a PC problem. Here's the specs: Windows 98, Microstar MS-6368 Socket 370 w/ PIII 866, on-board video & sound, 10 gig HDD, CD, CDRW, FDD, 56K PCI, 1 stick of 256MB PC133, etc.

When I press the power switch, everything (HDD, PS, CPU fan, etc) turns on but there's no video, no post beep, and no memory test. But if I wait long enough (literally 3-5 minutes) the PC will beep and post the initial boot screen then everything is fine form there.

Here's what I've done so far...
1) I stripped the machine of everything not needed and it still had the same problems. I left only the CPU, HDD, memory, on-board video and sound connected (no FDD, no Cd drives, and no 56K PCI modem).
2) Swapped HDDs, no change.
3) Swapped memory, no change.
4) Swapped IDE cables, no change.
5) Virus scan came back clean running the HDD on my PC as a slave drive.
6) I tried another PCI video card (but I didn't disable the on-board video if that matters any).
7) I reseated everything, literally everything (power supply connector, CPU, memory, all cables, etc).
8) I swapped power supplies, still no luck.
9) I reset the CMOS jumper, no change.
10) I replaced the CMOS battery, no change.
11) Tried different power cord, no change.
12) I have this plugged into my monitor, keyboard & mouse and no changes either (same problem as when system is using my friends monitor, keyboard & mouse).
13) I've also tried another pow... Read more

A:VERY, VERY, VERY slow boot/post

One thing you didn't try is flashing the bios.

I would tend to believe that the motherboard is at fault, but it only takes a few minutes to flash the bios

I'm not a computer guru but I do not know what the term is called when the computer starts up and you see the 'F1' through 'F12' commands.

My HPdv6700 laptop which has Win7 Ultimate 64-bit has not been able to get pass this screen. Basically all I see is 'hp invent' and stuck here for hours. Before it used to run fine with WinVista 32-bit.

I don't know but I was suggested maybe it's something with my BIOS?

Sony Vaio desktop, 2005, has boot hang-up, and after slowly going
through the obvious, my question is if there is something I'm missing?

Boot stops at manufacturer's and Pentium 4 logo after making one beep and message "Input 2: HP15. No drives recognized, so nothing with recovery disks. No keyboard shortcut to Bios. I've attempted:

1) replace power supply,
2) reseat memory chip after rest,
3) reseated RAM sticks and MB plug,
4) removed exterior plugs, was able to transfer some files from the HD to another computer.

Any suggestions for me at this point? I don't know what else to look
at except CPU/fan and the MB. Can always freeze and retry my HD, I guess. bookburn

I think that i have the same problem, i just installed a new mb and cpu, everything should be transferable/compatable, but when i start up it turns on , ie fans hd drives etc, but it doesn't load up, everything is in but no boot(post), the only problems i think that it could be is that the mb has both sdram and ddr ram, and my athlon xp/mb use a 266 fsb and the ram is 133, could this be a problem, i want to upgrade to the ddr, but moey is an issue, and i don't want to buy the ram right now unless it is the fix, trial and error is probably the only answer, but that can cost money. Could the motyherboard be bad???

i could try a new graphics card, but i thought the video test was after the ram/drive tests or is it first becvause the video info comes up first on the screen before those othersteps??? maybe i'll try as new card before ram, hmm

I recently have been having a very strange issue with my custom built pc. From the time i press the power switch to the time i get to the log in is about 15 - 20 mins. It takes very slow to do every stage of the boot process. If i try and enter the bios it freezes up. I'm not sure what to do but have come to fear turning my computer off because it takes so long to turn back on... Please help!!

A:Very slow post and boot... please help!

Are you using that computer right now? If so, I might want to check some BIOS upgrades. Try to identify your Motherboard, get to the companies site, locate your motherboard, and look for a BIOS update. That might resolve it.

I have a Dell Dimension 9150 running XP Home, it has two 160gb hard drives set up using array controller, striped.

It boots up to POST then black screen and halts. It wont load safe mode stopping at \system32/config/system.

If I put in an XP cd to try and load Recovery Console it stops because it cant see the hard drives at all. They do show up in the BIOS though.

I've tried to do a repair install but again it says it can find the HDD's.

I've looked Dells support site and it gives info on 'Loading PBR for descriptor....done.' message which this pc shows just before halting with a black screen. It seems the only answer left is a reinstall from the factory image, however I need the docs etc off it as I don't have an up to date backup :( I've got Getdataback and it seems to work however everything it finds is corrupted so useless.

Any help greatly appreciated.


A:Xp Boot Halts after POST

Test the hard drive for possible failure before trying anything else. The drive manufacturer's (most of them anyway) have free downloads of their own diagnostic software. The links are here: Hard Drive Diagnostics Tools and Utilities (Storage) - TACKtech Corp.

Since Windows won't start, you will need to download the DOS version of the diagnostic software. This is an ISO file from which you must make a bootable CD using IMGBurn from here: Download ImgBurn - FileHippo.com

When you've made the CD on any working computer, use it to boot your faulty PC from.
(You may have to go into the BIOS settings first and set the CD-ROM or DVD-ROM drive as the first boot device).

The testing software will load and you can test the drive.

I went out today and came back and my PC was stuck at the "Last known good configuration screen". I tried to boot into windows using that setting and nothing happened, my PC Just restarted and the cycle began back to that screen again.

I restarted, POST gave me no errors but i was still unable to get into windows, I put my disk in and attempted to repair my installation and once again it wouldn't load, I got to loading necessary files etc (With the bar at the bottom) then the PC restart after that..

I'm thinking it could be a hard drive issue, I've got a spare old hdd i can try, but before i pull apart my PC i thought id ask here.

It takes me roughly 4 to 5 hours, start to finish, to assemble a new PC and load the OS. I lost count of how many systems I've built over the years, but this one has me stumped, I've never seen anything like it!! I hope there's someone out there that can shed some light into what's going on....
I started out with:
Intel LGA775 ATX Motherboard BLKDP965LTCK (D41694),
Intel Core 2 Duo E4600 LGA 775 Processor,
Zalman Ultra Quiet CPU Cooler,
Mushkin 4GB (2X2GB) DDR2 Memory,
Logisys All Clear 550W ATX Power Supply (With UV Cable Management sleeves),
eVGA GeForce 9600GT Superclocked 512MB GDDR3 PCIe 2.0 Video Card,
Two Seagate Barracuda ES.2 500GB SATA Hard Drives,
One Sony 20X SATA DVD Burner,
and I added an AVerMedia AVerTVHD MCE A180 PCI ATSC HDTV Card,
HP w2207h Monitor,
Creative SoundBlaster Audigy SE 5.1 Channel PCI Sound Card.
I packed it all into an Blue Apevia Aspire X-Plorer ATX Mid Tower Case with enough mods to light up the whole house with a bright blue glow.
For the initial setup I was using my old 19" Viewsonic VGA Monitor, and I had done a full assembly on the case. Once assembled, I hit the power switch, the case lit up, all fans came on, the monitor came on for 15 seconds, then went to Power-Save Mode. Okay, I decided to strip it down to bare-bones to set it up, but it still did the same thing.
I ran to Fry's Electronics to buy washers for the Motherboard Stand-Offs, on the off chance it was grounding out. That wasn... Read more

A:New PC will not post or boot, $1,800 Nightlight

Go back to basics. Is it plugged in? Thermal paste? bad case, bad case switch, bad cable. We have seen this at least three times due to bad case pins, switches, or cables. It has to be there, right? You have a fundamental failure that you would not normally expect. Check your electrical box to see if one of the switches has been thrown open. Verified adequate electrical power at the socket. Do you have a volt ohm meter?
Test everything from that basic level.
Then, leave it alone for 24 hours. Get some rest. then when your frustration level is down and your sense of humor is back, get to work.
I would start out with the most basic system. Motherboard, CPU, thermal paste very thin, one memory module, and any bootable device... preferably a USB floppy drive or a simple optical drive.
Does it boot?
Keep adding components one at a time starting with additional memory... until you have tested each device one at a time, removing other stuff util you create a history for each component.

Hey all,

I've been messing around with this issue for weeks and haven't had much luck. Hopefully people might have some ideas.

A few months back my computer was off when I went downstairs in the morning. Probably a power failure. When I turned my system on the computer wouldn't post.

So, I pulled all my ram and cleaned my system. I reinstalled the ram and it still wouldn't work. I proceeded to start testing 1 ram stick at a time. Any 2 ram would work at the same time so I conceeded to work with a 2gig in my first slot and a 1 gig in my 3rd slot (the pair slot for slot 1). This worked for a few weeks and than one morning my computer wouldn't post at all.

So here I am now.
Today I completely stripped my system down and rebuilt. I added a new power source just as a suspicion and proceeded to try. Nothing, no post. I pulled all ram and put my 2gig in ram slot 1. No Post, I placed 1gig in slot 1 and it posted and gave me a Checksum error. Probably because I had pulled my battery a week or so ago. I defaulted in the bios and rebooted. Load took it to the "Windows did not load properly" and I chose start windows normaly. At this point I get the first windows loading bar and than black and nothing. The CD rom spools up like a mad beast for about 3 mins and than everything calms and nothing more occurs.

Today since getting it to post the screen has also had small horizontal lines (green and red) forming vertical bars down the scree... Read more

Whenever I turn my computer on, the light on the button, that is suppose to turn blue, stays yellow and the fan makes a loud noise, and it never did that when I booted my computer weeks ago. The problem started last week when me and my family moved into a new house. Everything is plugged in correctly, we checked the inside and nothing got loose or unplugged, we tried removing each of the ram (2X 1gig Crucial sticks), looked inside the psu and it seemed ok. What should we do so that we don't have to get it serviced or buy a new one? Thank you

A:Stuck in POST - won't boot

Seems that your COMS battery is dead. Replace it. It is a flat rounded battery inside the machine. Look at the type of battery it is and replace with the same one.

Then go into BIOS press which ever button to get into bios sometimes F2 or similar.
Press f9 or an option that will load defaults. Press F10 to save settings then it should work.

A computer I was working on for some reason no longer boots, nor does it display any post data that it normally does when booting.

It gives no screen activity at all, no beep codes, and I cannot make the caps lock or num lock LEDs light up on the keyboard. I tried this with two other monitors and keyboards, but still the same thing. I even tested the BIOS battery. I've made sure everything is securely plugged in inside, and I even tried unplugging everything I could, but still no luck.

Any ideas??

I have had this setup for over a year now and it has been working fine, there have been no symptoms leading up to my problem.

Computer froze, and on reboot would not POST, with no error codes.

Fans spin up, but no signal to the monitor,
Normally at boot GPU fan revs up to highspeed momentarily than ramps back down, but now it revs up and stays up, reset button does nothing have to hold power button.
PSU fan is not spinning during boot up but I am not sure if this fan is heat activated or not.

I have unplugged all non-essential devices leaving just RAM, CPU, GPU.
still no joy.

The last thing I have done is remove both RAM modules, at this point I do get either 3 beeps, then reboot and continuous.
Or I just get continuos beeps.
And the GPU fan does ramp down.

I have tried both Ram modules in all possible configurations to rule out Ram slots, always no beep codes with Ram plugged in.

So this leads me to believe it is either the PSU, or RAM is there any test I can try to tell which one, short of swapping as I have no spare parts handy.

Hello everyone, I'm here to request some assistance with my computer that has stopped working.

OS:Windows 7 Ultimate 64
CPU: Pentium 4 G2120
GPU: HD 6870
RAM: 4GB Crucial DDR3 1333mhz

Firstly, on my Gigabyte GA-Z77-HD4 motherboard, I was having an issue with the ram (There was a continuous beep), so I tried another stick of ram, and there was the same problem. I figured that there was possibly a problem with the motherboard itself, because previously I had the same problem and it was fixed by placing the RAM into a different slot. And so I purchased another motherboard (Gigabyte H61M-S1) today, and tried running. I was still given the same error. I bought another brand new stick of RAM and tried that; still no luck. I have already tried running without GPU (using on-board), but still the same error of the continuous beep. I have also tried cleaning out the other RAM sticks, among changing PSU's. I have a slight feeling that the stock cooler I have on the CPU may no longer be sufficient for the CPU, and the problem might lie there. I have also tried bread boarding the build. Thanks for your help in advance.
