Computer shutting down by itself
as title says, my pc randomly shuts down. i believe it's overheat(?) since it mostly happens when my pc is under heavy load and it starts making some weird "alarm" noises, anyway to check it?
first time having problems with this kind of stuff... i recently upgraded my pc, so i was thinking maybe power supply is not enough?
