Drivers not allowing Startup???

Computer Statistics:
motherboard: P4S800D-X
Processor: p-4 3.2Ghz
Video Card: ATI All-In-Wonder 9600


This is one of my friends computers, he just moved out to southern california because of the military, we just got his computer all hooked up last night and it would not start, it would go throught the Bios Boot and the Post(1 beep from POST) then after that it would give me the windows boot screen and then would restart itself. ive been able to start it in safe mode, and a diagnostic startup, but the thing to get it to load into the diagnostic startup i have to disable all of the drivers, havent been able to narrow it down to what could be the problem one, or if its even a driver at all. Ive had the computer boot up in normal mode once but as soon as i logged on it shutdown on its own. completely turned off without the shutdown sequence.

We've run Virus scans and had nothing come up, same with chkdsk. any help would be appreciated even if this is not the problem and you could get me pointed in the right direction. Ive never come across this kind of problem yet

Edit: Im also unable to view the Event logs, i can get into them but when i click on the type,Application, security, it says that their not their

 

Event Logs gives me the error that: The Interface is Unknown

Try this: boot to the Windows boot options menu by pressing F8 at start up. Select "disable automatic restart upon system failure" and continue booting. Instead of the PC crashing and restarting, it should stop on a blue screen error. Write down the error number (they look like STOP:0x0000007E) and any error message and any filename listed. Then post that info here and we'll go from there. You should also consider running an extended in-depth hard drive diagnostic with the utility downloaded from the drive maker's web site; these diagnostic tools are free and will create bootable floppy or CD. A memory diagnostic is a good idea too. I like the Microsoft Memory Diagnostic; the download will create either a bootable floppy disk, or an .ISO image file in My Documents. You'd then burn the .ISO as an image to a CD and boot to it. If you burn it as standard data it won't boot. So, you boot to the memory diagnostic and press 'T' for the extended tests; run at least 3-4 passes. It may appear to lock up (esp. on test 7) but it hasn't. The extended tests take time (as do the hard drive tests) so be patient.... :-D

 

We had figured it out about a day or so after i asked on here i just havent had internet access to post that i had it fixxed.

The problem was cause by a WNIC that was removed incorrectly, my friends brother took it out of his computer without uninstalling the drivers and that was what was causing the computer to crash, we installed a new Wireless NIC and then tried to boot up and everything worked fine. Im not entirely sure on why it happened the way it did but we have it fixxed.

Thank you for you help and time
