While i'm play games, my computer will randomly hard freeze, requiring me to shutdown my PC. It could be 30 minutes into a game, or 3 hours into a game. But it seems that when I freeze on a game once, and play it again right after the freeze, the time it will take to freeze again will be shorter. I've already ran two RAM tests which told me my ram was fine. I've updated my computer's graphics card and downloaded all window updates. I've bought a new graphics card and power supply, still freezes. The computer only freezes on games too, not if i'm just using a software or google.
