I have a problem with my PC restarting while playing games. Sometimes it happens 15 mins into a game and sometimes two hours in. It happens more in some games than others, particularly GTA IV and Fallout New Vegas. The system remains stable while not playing a game. My setup is listed below;

M4A78-EM mobo flashed BIOS to support Phenom II
420 Watt Antec PSU
Phenom II 965
HIS Radeon 6870
4 GB Ram

I think it may be a power problem. I ran prime 95 for CPU a half hour, the system was stable with CPU heating up to 60C. I also ran a FurMark for GPU for 20 mins, it topped at 83C remained stable. In any game, the temps reach a maximum of 75C, according to GPU-Z, so I have a hard time believing it's a heat issue. While the system remained stable during each stress test, while playing a game both CPU and GPU are working hard, so maybe it's this combination that causes a restart.

Am I completely off? If anyone has experienced something similar and fixed it, please reply.

I have experienced this with a $10 500W PSU eventually ending in the PSU blowing up. But since you have an Antec PSU, I doubt that is your problem.

your 420w psu is not enough. that is the only 420w psu antec make, and it only has 18A on the 12v rail. go buy yourself a new psu with at least 35a on the 12v rail.
