While playing MoH Warfighter my comp will lose video signal and the sound will shut off at any given time during play. The only way to recover from this is to reboot. I've checked my video card temps and they're around 40c-50c while gaming so I don't think it's overheating. I updated my video driver to the latest version and it still happens. I'm assuming it's my PSU starting to crap out. My build is only 6 months old and my video card is only 3 months old.

Okay, I just tried playing counter-strike:GO and it happened before I even go to the main menu
