I just updated my bios to the latest one, the friend who reinstalled Windows thought he had updated it, but apparently he hasn't. I will wait to see if the PC keeps on doing this. All temperatures on all components are ok, I've checked them.
(Apologies, if this is not the right place to address this problem.)
I recently bought brand new parts and assembled the system all by my myself. I will first give you the specs and then tell a bit more about the problem I have with it.
Specs :
Motherboard - ASUS S1151 ROG STRIX Z390-F GAMING...
