Question Windows 11 restarts when I'm away from my computer ?

[true1hart]

I'll be doing some work and maybe have browser open , email, etc. Then I leave my computer on for a few hours. I don't lock it or put it to sleep. And no apps are running. Only the screen is set to shut off after 5 minutes.

Upon my return, the computer is at the login screen as if I rebooted.

I can't for the life of me figure out why this happens. My computer doesn't freeze or reboot when I'm actively using it.

--- It's not Windows Update ---

Go to the Windows event and in administrativne templates check what errors have been reported.

Can it be my memory OC or AMD Precision Boost causing this? I wouldn't expect since gaming, video editing, browsing, doesn't cause any freezes.

Here are some messages around the time it may have restarted:
