iBUYPOWER TraceMR 2040 randomly rebooting
my pc is specifically iBUYPOWER - TraceMR Gaming Desktop - Intel i7-12700KF - 16GB DDR4 Memory - NVIDIA GeForce RTX 3080 - 1TB NVMe SSD , had it for about 3 years now, only thing i've changed from the prebuilt is adding another ssd.
What has happened 3 times now, all while i was playing games, is the pc randomly shutting down and then coming back on again within seconds. The first time was a few weeks ago so I don't remember much, but the latter two were both today, pc shut down and restarted and I immediately hopped on the game I was playing again only for the same issue to reoccur about an hour later. During this time around when the pc would reboot I would experience issues like the game I'm playing slowing down unexpectedly, or a video i had on the side freezing its visuals unless i was focused on it, and if i did that the game would slow down again. It was nothing so egregious that i stopped playing immediately, but its definitely not the norm (i wasnt playing a new, suddenly more intensive game either).
After the second shutdown today I took the pc apart, reseated the ram and did some dusting out of the pc and im going to install something to track the heat to make sure its not a cooling issue, because all the times this has happened so far is when i have been running a game for hours. I also check the event viewer but I don't know much about how that works, the only message that seemed helpful was one that said "the proccess StartMenuExperienceHost.exe has initiated the power off of computer [my pc's name] on behalf of [my pc username] for the following reason: Other (Unplanned) Reason Code: 0x0" but I only saw one other post after a quick search talking about a similar code.
Hopefully what I did solves the issue but I've read some posts about ibuypower psu's or cpu cooling having issues so I wanted to ask and see if anyone else had the same problem before so if it happens again i can know what steps to maybe take next.
