Question How do I fix this rebooting issue

[Coopruck]

I have just recently upgraded form a ryzen 5 3400g to a ryzen 9 5900x and when I go into a game it is fine for a couple of minutes and then it just randomly reboots out of nowhere. When I am on the Home Screen it is fine and I can leave it on the Home Screen for a long time without it rebooting. Somebody please help.

The temps are good by the way.

They may well be, but we can't help you diagnose this without full system specs, including the brand and model of the power supply. Not just wattage, that's no good, we need specifics on that one given the issue you are having.
