I’ve just recently bought a new desktop and for about 2 weeks everything was fine. About 3 days ago whenever i’m playing games, after about an hour it’ll hard crash and my entire computer will freeze. The only way to fix it is by turning the pc off and back on. I’ve tried a memory test, i’ve tried taking a ram stick out and putting it back in. And I’ve checked for any system corruption files. But my computer can’t find any problems. I thought it could be overheating but when I check the temperatures are perfectly fine.
