Hello, I'm having trouble with random crashes while playing games. I have a nvidia 6800gs video card with the latest driver, I have also tried using older drivers but with no success. I have recently been wondering if it could be a problem with my power supply its an Eagle ATX500w can anybody tell me if they are any good? When it crashes I some times get the blue screen message 'nv4_disp.dll is caught in an infinite loop' also the fan often changes speed when its abot to stop. I hope someone can help me with this annoying problem.
