Crashing Issue - No Error Message

I can't play for longer than 10 minutes without the game crashing with no error message or my entire computer restarting. I limited my FPS, turned the res down and
turned all textures down. I even went as far as to find the anticheat files delete them, restart my PC, redownload the anticheat and update it. Nothing seems to work for me so far. Any tips would be greatly appreciated!
