Every time I try to play GTA V or a similarly demanding game, my computer crashes and becomes 100% unresponsive, forcing a hard reset. I'm not sure what's happening here, or even how to diagnose the issue. The nature of the crash is strange, because a very short glitchy audio tone is played and then the frame just freezes. I would appreciate any input, but the only think I can think of is that my CX600 PSU isn't giving the computer enough juice while it's under heavy load, although I don't think the nature of my computer crashes really fit the bill for a power supply issue. I'm just hoping that nothing is wrong with my graphics card.
