Randomly the other day, my PC just shut off my itself. I dunno what the hell happened, it wasn't power outage related. So I do the normal troubleshooting, taking everything down to a bare bones system (mobo, cpu, video, memory) and it seems to work. As soon as I add any hard drives the system boots, and then shuts itself off. I've reset the CMOS battery, the whole enchilada, and I get absolutely nowhere. Can't have enough peripherals to load XP, or to get a successful POST. Any ideas?
 
I was able to keep the PC up all night without a single HDD connected to it.

Here are the specs:

Asus A8N-SLI Deluxe
AMD 3800+ X2
Kingston Value RAM
BFG 600W PSU
BFG 7800GTOC
Maxtor HDD's SATA and PATA
Random DVD optical drives
Sound Blaster Audigy 2
