Computer stalls after pci device listing

[nater]

I returned from class the other day to find that my computer had shut off. When I turned it back on, it stalled after the pci device listing of the bootup process. No error messages come up, so I'm clueless as to what's wrong. I've reseated all the pci cards and checked all of the connections. The motherboard sees the processor, runs the memory test, and sees the hard drives and cd drives. I'm running Windows XP on a shuttle ak31 with a 1.4 tbird.

update:
tried clearing the CMOS, still having the same problem. After I moved the jumper to 2-3 and then back I got the CMOS checksum error message,which I took to mean that I had successfully cleared it. A few more details that might be pertinent:

the bootup sequence is reading my processor as a 1050 mhz, not 1400 like it should.

on the pci device listing screen there are 10 devices, all have zeros in the boot no. column except for the video adapter which has one. Oddly, after about half a second after the list is made one of the 0's in the bootcolumn disappears so no number is there. I have taken out all of the pci cards one at a time, and then all of them, and it still won't boot, so I'm thinking that it's not one of the actual pci devices.

Thanks again all for taking a look

Have you tried resetting the CMOS?

I took the battery out and put it back in...do I need to do the jumper thing to actually reset it? Thanks

Yes. Anymore removing the battery just clears the time and date.

bump for an update. Thanks for helping out

Remove all pci cards from the machine, and whatever addon cards are there. disconnect the HDD cables from the motherboard itself. leave the fdd cable as it is. Set the CMOS sequence to boot from floppy first. Auto detect your IDE settings in the CMOS, and necessarily this should be none for both primary and secondary IDEs. In case you have set all to auto then you may skip this step. Then boot up the machine, and give me a feedback on any message that you see,so I can guide you further.

First of all, your drop is speed is coming from the fact that when you reset most BIOSes, the FSB speed is dropped down to 100. The easiest way to tell is to just look at the numbers.

1050 = 10.5 * 100
10.5 * 133 = 1396.5 ~ 1400Mhz

So just change your FSB back in your BIOS to 133. My old board had a switch to go from 100 to 133 easily and also had a incrimental FSB change option, just change whatever's needed.

As for your problem, I've seen one instance of this problem before, but in that case, it was a virus that was causing the computer to not boot into Windows XP Pro.

If you think it is something software wise, I recommend the Windows Ultimate Boot Disc ( http://www.windowsubcd.com/ ) as a way to clean those virii out (since you probably can't even get into safe mode). It has tons of tools built in that it runs in memory using Windows XP's built in Preinstallation Environment.
