I built a new computer over christmas break this year, and I have no real issues except for one: Every once in a while, even when just on the desktop or something, the computer will power down. It's epidemic sometimes, I've had it do it 3 times in less than 10 minutes. I replaced the heat sink on the processor from stock to a thermaltake big typhoon VX, and the problems are still persisting. I can rule out the PSU because I already replaced a faulty one (a 4-pin was broken). My system is as follows:

Motherboard: XFX 750a SLI
Processor: AMD Phenom X3 8750 black edition
Video card: EVGA 8800 GS superclocked edition

tell me if you need more info.
