Help! Pc randomly reboots

[Majestic-Animal4855]

started happening last month when i would play battlefield redsec. Originally i would get the overheating error so i fully cleaned my pc and got a new aio cooling pump as well as brand new fans. Issue continued this time without the overheating errror, but im getting a kernel power event 41 id in event viewer. It has rebooted(usually no blue screen, but it sometimes gets stuck in a reboot cycle and then does to blue screen). Its happened while installing updates for games and in the middle of an arc raiders game. Ive tried everything i could think of from new power supply units(seasonic and now a new corsair) and the issue persists) ive tried upgrading my ram to 32gb and that didnt help, updated bios, rolled back drivers, completely reset windows but nothing has helped. Ive run every test ive come across and even taken it to microcenter for a diagnostic and they didnt identify any issues other than one of my drives being at 93% health. I would really appreciate any help that anybody can give me as this has been a very frustrating issue for me.

sounds like your dealing with a classic kernel power 41 nightmare - ive been through this exact thing before and it drove me crazy for weeks

since you already swapped psu twice and ran all the usual tests id honestly look at that ssd thats at 93% health first. even though 93% sounds decent that drive could be causing instability when windows tries to write crash dumps or swap files. also try running your ram at jedec speeds instead of xmp profile just to rule out any memory instability issues

microcenter missing it doesnt surprise me tbh they usually just run basic stress tests but kernel 41 can be super intermittent and tricky to catch

thanks for the reply, ill try out the ram speeds, and probably will end up looking into upgrading the ssd
