I've had my computer for about 2 years and all of the sudden, my pc starts to reboot itself. It first started when I was about to play Rocket League, barely 20 seconds into playing the screen turns black and the pc has begun to reboot. Then when I get into the computer again, and about 5 second into loading Discord it reboots yet again. While that next time I log into the computer again, it reboots practially immediately without having loaded in anything. This all of course happened in a couple of minutes, however when I shut down the PC for a couple of minutes and turn it back on, its fine. Until I start playing again of course... I've tried playing 4 different games, the PC reboots pretty quickly either way. I've checked with the temperatures and it all seems good. GPU is about 30'C idle and only gets to about 55'C in game before the PC reboots anyway. While for the CPU I did run a IntelBurner stress test where everything seemed just fine.
 


There was a certain Kernal Power 41 which showed critical.
But I would suppose if it was the PSU, this would have happened much sooner. Why would it act out now?
