I got a new PC around 3 years ago and had this randomly occuring problem since the start (Like after 6 month it happened first time i think).
The PC just shuts down as if the power went out.
Nothing visible in the windows log about any problems.
The only old parts from my old PC (which never had this problem) i transfered were SSDs and M2s and my GPU which was also replaced by now.
I also replaced the PSU because i suspected a problem with it but it still happened after.
I already gave up as it only happened once every few month so it was only slightly annoying but now i had it happen once per day the last 5 days which would be too annoying if it keeps happening.
2 years ago i already tested some stuff to find the reason.
GPU and CPU stress test for multiple hours, RAM testing via memtest, bios update.
I also replaced my Old 1000w MSI PSU with a 1300 Watt be quiet! Dark Power Pro 13.
I uninstalled not needed programs, disabled everything from autostart which is not always needed but it was still happening then.
Checked if cables and everything is plugged in correctly.
Cleaning dust regularly.
Not sure what else i can try, i have some knowledge about PC due to using them since ages but im also no expert.
Let me know if you have any idea what i could still try or if you need any more infos.
