I built a PC about 4 months ago, and for a while now, I am having a problem with the PC crashing while gaming. Everything just goes black, and I have to turn it off and back on to work again. But I never get crash reports so I don't know what the problem is.
Is anything overclocked? What is the power supply brand and model? Did you check temps to make sure system is not overheating? Did you test the video card in another system or another video card in yours?
