The title is essentially it. Emergency restarts started a few hours ago. PC's 3 years old, built by PC specialist with no previous issues where the PSU is concerned. Opened up the case and checked all the connections were secure, no issues there. There are also no problems at all on reboot or general use, however when i fire up games the problems start. The time it takes for an emergency restart to occur varies, ranging from less than a minute all the way up to 30 minutes into the round. Much of what i find on the internet seems to be somewhat contradictory, some even suggesting turning off the Asus anti surge protection which just seems insane. Anyway, somewhat of a loss at what to do going forward, hoping i don't have to replace the PSU as i haven't wired a PC since college, and after 12 years i cannot say i remember much :/
