I have a new PC. I bought it 2 months ago. I mostly play games on it such as CSGO. It worked fine till last week. Now, after about 1-2 hours of play, my game freezes, and I get a black screen, some strange sound, and then it either puts me back on desktop with my game still running but not functioning, or it puts me on the Windows error screen and restarts my entire computer. If not than it just close up my game.
