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,

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 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...

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.

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

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'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)

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.

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,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.

The dvd drive has power and will open/close.

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 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!

So I bought my girlfriend a CD R/W drive for her birthday. She tried to install herself and ended up breaking the power switch on the front panel of her computer case. I go over and find the power switch broken useless, not repairable. Off to the store for a new case. I install everything into the new case and power up.....nadda. Since I didn't have the manual to the MB anymore and since I didn't realize that the row of jumpers for power, power LED, reset, etc. were vaguely marked I realized I missed by one pin on the power switch. I moved it over and powered up again. This time the drives power up, status LED on MB powers up, all fans power up, but no post, no beep, nothing. And the power switch doesn't power down, I have to hard power down at the power supply. Figuring I toasted the MB somehow I went out and picked up a new MB. Once again swapped everything out and same thing, everything powers up, but no post. And this is where I'm at....soo....

What the hell did I do wrong? I tried pulling everything except the HD and video, still no post, the HD doesn't even self check (I can't hear the head unlock)

At this point I am thinking, either the new case has a bum PS in it, I killed the PS when I miswired the soft power button (I doubt that) or something else. I dunno, and I need help. This is getting ugly.

A:no post, boot, nothing (longish)

Motherboard may have come with theCMOS jumper in "Clr" position- it wont start that way, you have to move it to "Normal" it's a 3 pin connector, they are labeled in most. That's one possible cause...

Screws that hold motherboard- are any touching anything other than the mounting holes- any put in, forgotten about, that did not line up with mounting holes in board?

Try reseating everything. (I know, you did it a hundred times...check the jumpers- by the book.) Reseat video card. Check all cables, for pin1 to pin1, and if you have an 80 wire blue or other color coded cable- put that end down on the motherboard to IDE port.
You could try a different power supply, too, make sure its an ATX if thats what you have in case now...If its a P4 system...plug the square extra power plug into motherboard to power CPU.
RAM module- if its a DIMM, single- should be in RAM slot 1 or 0.
Try different cables, maybe, or power supply plugs...
For the replaced power switch- they can be confusing, polarity with them is sometimes reversed. Try reversing 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.

A:slow boot up POST

There are a couple of things you can check / set to speed the boot process up.Keep in mind a slow boot does not mean there is anything wrong with your machine.
In the bios there should be a setting to 'allow quick boot'
Disable unused ide channels if any .
Set the boot order to start with your HDD first.
Also in Windows minimize the number of programs/services that auto start.

I'm working on a friends' computer that he put together himself. I'm pretty good with computers, as I run a website and repair/set up networks all day for a living, but this has got me stumped. I have an ATX 350 power supply with a Asus TUV4x board, a PIII 1.2 ghz processor. The problem is, the BIOS does not support a 1.2GHZ, just a 1GHZ. Now there was an update for the BIOS to support the bigger processor that I downloaded. The other issue is the computer won't boot. After POST and drive detection etc. the system hangs and won't seek a boot drive. I removed all extra components (HDD,Sound card,USB mouse, extra sticks of RAM, etc.) leaving just the video card since it don't have a built in one. Still nothing. I removed the battery unplugged the PC and set it for 30 minutes to reset the CMOS still nothing. I set the processor speed to 800mhz so it would run on the board. Every time it hangs when I reset it I get the invalid cpu speed error in the BIOS menu. Any information would be greatly appreciated.

Hello all~
I recently acquired a free desktop computer from a friend. He couldn't get it to work, gave to me, and he bought a new one.
Anyway, When first plugging in the PSU, and before i push the power button, the computer begins to boot up by itself. The lights, Hard drive, fans, etc will operate for approx 10 seconds (timed it with stopwatch) and then will completely reboot. Nothing appears on the screen at this time. No bios options, no motherboard splash screen. Nothing. This will repeat over and over if i let it (i couldn't handle more than 5 minutes for fear of further damage.
Here is the kicker, at ANY point during this boot loop, if I press the RESET button on the front, it will exit the boot loop, and boot up like there was absolutely nothing wrong. I let it say on for 4 hours, operated just fine.
Once i go to power down (throught the start menu, SHUT DOWN), it will power down just great. BUT, 3 seconds after being powered down, it will try to boot itself again and begin the boot loop cycle.
I have updated the BIOS to the most recent via a thumb drive and that was successful. The default settings are chosen and I verified that the setting for booting after power down is off in the bios.
I have tried with 2 sticks of ram, 1 stick, and 0 sticks. I have unhooked the CD/DVD drive from the PSU. Tried only running HD, MOBO, and PSU but still a boot loop scenario when plugging in. I even tried a spare PSU I had on hand with nothing... Read more

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

Hi, and welcome to TSF.

The only information I can find about this code makes me think its being generated by your monitor. Did you see a message saying " Out of scan range"?

Do you have another monitor you can try?

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.

A:No boot no post no beeps, help


Used multimeter on 4 pin molex connector, and 5v and 12v rails are fine.
Tested Aux connector and 3.3v, 5v, and 12v connectors are also fine.

Is there any way to test the voltage running to my Ram slots?

I was wondering if anyone could help me here ,
I have this board and it just doesn't want to post at all .
I have tried two CPU's a 2200+ and an 1800+ and neither would fly.
I have tried this with ram and no ram since I only have 1 stick of ram and I know it works as it's from my other PC.
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.
no ram no video cards.

any idea's

Hello, please help. My Gateway GT5056 p.c. began to act strange, got worse and now may be dead. All of what I describe below happened over a period of a couple of weeks.

I first noticed a lot of HD activity when the computer was idle, that appeared to be the system idle process.

Then I got the following blue screen error message.
Stop: 0x0000009c (0x00000004, 0x8054D5f0, 0xb2000000, 0x00070f0f)
Beginning dump of physical memory.

I was able to hard restart, then I had two separate occasions that the monitor display would go hay wire (similar to the old t.v. sets where the vertical or horizontal control was out of whack) no error message with those occurrences. I was still able to hard restart.

Then I got the same blue screen message as above. The difference now is that it will not POST or boot up at all. All I get is black screen.

The HD and the monitor test fine in another p.c. I have tried it with one ram chip and no ram chip. I have unplugged (one at a time) and tested with everything that could be unplugged. The Gateway does not have a separate video card.

Any suggestions on how to troubleshoot this will be highly appreciated.


A:P.C. will not boot up or POST! Aggh! Help please.

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.

GeForce 7600 gt - graphics
1gig of ram
windows xp
athlon xp 2.2 ghz processor (i think)

the problem is the computer has been locking up at random recently
so i have had to reboot and then it works fine.

but now it wont boot at all with the monitor saying no signal
ive unplugged the hard drive and all other components and cleaned everything and re-assembled, but no joy ..........with there being no signal on monitor ive bought a new graphics card hopeing this would solve the problem, but no joy.

ive checked all connections and made sure all the power connections are ok and they seem to be ok.

the one thing i have noticed is there is a small fan over the M/B chipset which is not working. does this mean my M/B is dead ?

any ideas or help would be much appreciated

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.

Hey folks,

I have a slightly old-ish Compaq EvoN15 (AMD4) laptop that has completely given up and produces the following error shortly after the "COMPAQ" logo appear after you switch it on:

Err 5:Error Finding VFLOPPY.SYS
Err 8: Fake floppy driver not found
Press any key to boot active partition

After i press any key, the HDD light will stay on, sounds like it's doing nothing, but it doesn't, i'm just left staring at a black screen.

I have tried re-installing using the Compaq recovery CD's but the laptop simply will not boot from them, even though it is set to boot first in the BIOS.

I'm fixing an hp 533w for a friend. the problem is there is nothing on the monitor when i boot.no bios, no setup, no beep, nothing. everything is snug and in place on the motherboard.i have reset the bios, no luck. The power supply light in back is green , and the one is front is on as well, but nothing on the screen.every forum i have been to has suggested the power supply as the culprit, but i thought i would ask the opinion of all the genius' here. if anyone has any other ideas or similiar probs, plz let me know. thank you

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
