Windows 11 periodic and spontaneous reboots

I am looking for help identifying the cause of periodic spontaneous reboots that generate the "unexpected previous system shutdown" system event message.

The system is a Lenovo Desktop running Window 11 that has been spontaneously rebooting 1 - 2 times a day.

I enabled the driver verifier yesterday and the first spontaneous reboot since then was this morning.

Here is the link to the minidump files and the msinfo file:

Thank you.

 

What could cause my PC to reboot spontaneously?

Having run smoothly for years, my PC spontaneously rebooted on 26 June and has done so about 30 times since then, sometimes running a week without problem, sometimes rebooting twice in one day. The screen suddenly goes black and it reboots. There is no
blue screen or error message displayed. The event viewer does not report any significant error other than event 41: The system has rebooted without cleanly shutting down first.

I always run the latest version of Windows with all updates.

What could be causing the PC to reboot spontaneously?

 

Windows spontaneously reboots

Windows 10 spontaneously reboots without an error message on screen or in the logs. I've reinstalled all drivers, replaced components, added cooling, removed GPU, removed tablet, removed Wi-FI card, run system, memory, and CPU tests, repaired window, and
re-installed windows. Nothing has solved the issue. It does not appear to occur in Safe Mode, yet it's not clear which windows component or driver left would be causing the issue.

Any suggestions for diagnosis?
