Question PC rebooting and games crashing

[geomilios]

Hello guys,

I recently built a PC and I had problems with random reboots using windows 11 and a most possible faulty power strip. I went to a store in order to give my PC and fix it and they fresh installed windows 10 and downloaded all the latest drivers. They told me that my PC was working just fine so I took it back to my place. I just downloaded GTA V and It takes two and when trying running them the game either crashes without any warning or error message, or the PC reboots. I ran FurMark to test my GPU and the PC restarted after 8-9 minutes of stressing with normal temperatures (~ 65-68 degrees Celsius). Other PC components run at normal temperatues too. What could cause all these?
NOTE: For some reason, I can play League of legends without an issue.

Hi
Did you Thermal paste when installing the Arctic Freezer 36?
