Ty, im gona try swap the PSU, there is any other test i can do?

You have correctable error happening (if is not correctable it generates BSOD), check Event Log to see if there is some useful information about it. Something is generating those errors, you are running any overclock?

Hi guys, i need some help. I have a weird problem, in the last month or so my pc started doing some random turn off. It only happens in these conditions Idle(ish) and cold, usually when i am reading something, watching an youtube video or idle. Never happens when running some game, emulation or heavy workload. The problem started in ~august and happened 6 times. Does not generate BSOD or Event Log. It simply turn off like pulling the power plug from the wall (im not doing that, checked). I have the feeling its related to the last windows update. Because the problem started at the same time windows update update f*cked my dual bot (Grub error unknow filesystem). My system is old but im not upgrading it yet. To mitigate this problem when i have Teams meeting i start Heaven Benchmark on the background. Help pls.
