It has been happening for quite a while now that my computer shut down when I was playing games. Sometimes it happens after I play for a while and sometimes it happens the second I enter the game. 2 days ago I played a game for 8 hours straight and nothing happened, while yesterday my computer shut itself down 3 times when I entered the same game and twice after playing for about 20 minutes. I have tested the ram with memtest and it didnt show any errors, I did the torture test for my cpu with prime 95 and it worked fine and my gpu went up to 90°C while testing (which is more than it ever is while gaming) and nothing happened aswell. Some people told me that it might be the psu that is causing this. I would really appreciate any help
