Alrighty, so I have been having crashing problems. I would play games for a little while then under certain load my whole computer would shut off. I figured it was my video card (MSI Twin Frozr II 5830). So I did a stress test on my card and CPU. It turned out to crash on my card. So I unplugged the card and ran off my motherboards graphics. Everything ran absolutely fine. I had no problems I even played Blacklight Retribution (Though it was horribly slow). So I really was positive it was my card. I then went out and bought a new card, a XFX 2GB 6950. Plugged it in today and the problem still exists only it happens sooner. I can't even get to the game menu. This makes me think its the PSU. Since this card requires a bit more power and adding a card would cause my PSU to hit a certain peak. I think once the video card gets going and puts more of a load on the PSU it decides to shut the computer off, but it's unlike a normal shut off. My keyboard, mouse, and display will shut off and my fans will keeps going. I cant turn it off by hitting the power on my case I have no idea why. So I have to hit the power switch on my PSU. I'll turn it off and let it sit for a few seconds before I go and turn the computer on again. It will boot up fine after this. The computer can be a bit finicky once it boots up, but it's because it's booting from a crash. A proper reboot fixes that. So I want to ask the wonderful community of people who know more about this stuff than I do on here whether you guys think it's the PSU or another component. I'm very much hoping its just the PSU. Thanks!
