So I just built my computer 1 week ago and since then I have not been able to play a game for more than about 20 minutes. I recently took it apart and put back in the stock cooler and was able to play for a good 4 hours without crashing. The next day it went back to normal and I am still continuously crashing no matter how small the game is (i.e Heavy bullets). I tried downloading minecraft to see if it was just steam games that were crashing but nope, minecraft crashed too, along with League of Legends. I have tried so many things such as checking temp while playing, checking my CPU and disc usage which reach very high even about 100% when playing. It seems to crash a lot faster when I play games online so I'm thinking that it may have to do something with insufficient permissions? I'm not too sure.
