Please help me look into this problem.

I don't know if this game patch has a problem or not, because when I play a game, the screen turns off but the computer stays on. This normally doesn't happen before the patch update, I can still play normally. I've tried playing other games that require higher specs and haven't encountered the problem mentioned earlier. My computer specs are 5080/7800x3d/32g/m.2/1000w 80plus. Please help check or verify or advise me. I have had to move to play on a notebook for several days now before I can play. I've tried to find a solution, whether it's updating the software or anything, but it doesn't work. I even went as far as reinstalling Windows, but it didn't work. Thank you.
