Computer reboots for no reason...

[LanEvoVI]

I'm building a new computer for my roomate and it keeps randomly rebooting. Sometimes it loads all the way into Windows and runs fine for a while. Then it just automatically shuts down (goes through the whole process where it actually shuts down Windows first and sometimes it just powers off w/o any of that.) I'm convinced the computer is possessed. I took out all the cards except for the video card and it still randomly shutdown by itself. Any one out there have any clues for me? Here are the specs on it:

AMD Athlon XP 1700+ w/ the Retail Heat sink (temps are steady at about 45C at full load)
MAXTOP 147KG2F-USB w/ 350 AMD approved PSU
256 MB Micron PC2100 DDR Ram
Gainward Geforce2 Ti 450
Epox 8KHA+ KT266
Creative Soundblaster Live! 5.1 Value
16X Lite-on DVD-ROM
8x Iomega CD-RW
Western Digital 13 GB 7200 RPM
Maxtor 20 GB 5400RPM
Intel 10/100 NIC

Four suggestions:

1. Flash the latest mobo bios.
2. Try your RAM in a different slot.
3. Try different RAM.
4. Try a different power supply.

Seeing as how my other posts were locked and I haven't received a suggestion that has worked yet...I'm just updating w/ my current status.

I've swapped powersupplies and still no go. Still getting sporadic reboots w/ no error messages from Windows. I don't really feel safe trying to flash the bios as the computer restarts/shuts down at random moments.

edit: I just tried swapping different sticks of ram in different slots on the mobo, and still no go...its really starting to look like this is a motherboard problem...Any last minute suggestions b4 i RMA the board?

Flash the bios. That reboot problem is not uncommon on the EPOX 8Kha+. I've had teh exact same problem with my Epox before.

Go into the bios and sit for a while, if it stays then feel safe about flashing. I have read in other forums that the 8kha has this issue. After flashing if you still get this post back.

Windows XP? That what XP does instead of the blue screen error, it just politely restarts itself without asking your opinion

I've heard of quite a few people having problems with that PSU, and a bad PSU is the normal cause of the type of problem you're having. Might want to try switching it out for an Antec or a Sparkle.

I would've also guessed the PS. Are you sure it's XP not just AMD approved? If it's not the PS perhaps there is a short. Re-seat the motherboard.
