Hi my pc: 10850K stock 4800mhz

Hi . I have an question. 5 days ago i had momentary power outage for brief moment. When power back pc not booted itself. I just presset reset button to turn on pc.

In bios i have option RESTORE ON AC POWER - ON.

But when i cut power by pressing off BUTTON on power cord for second and then turning on pc booting itself on.

Is any difference between short power outage and turning off/on power in power cord? THanks

probably the power was not off long enough.

4 days ago…i launched Metro Exodus and during advertisement part,my pc just shutdown. I pressed power button,rebooted and its fine again.

Happened after launching game on intro advertisements part.

My question is. It was psu issue or maybe other hardware?

I remember that when pc goes off ,pc case lights flickered for a second and then turned off completely. That flicker not happens when i shutting down pc manually.
I have checked to ON in bios: Automatic restart after power loss.

Also monitor flickered 10 seconds after shutdown.


In my room i had laptop on connected to other power cord in this moment, and in eventlogs there was not log about power mode changing to battery.So i think power was on in house. Also router plugged to wall dont turned off, because WIFI was active on laptop ,though.

ps:
I doubht its hardware related because since 2021 march i launching Metro Exodus Hundred times and never shutdown.
