Hi
This is not hardware issue given the fact that I'm using an Intel i5 12600 + 5700XT AMD and I get these shutdown.
There are not reboot but clean shutdown however as mentioned before unexpected (windows event logs)
I've for my part be able to fix it.
* I've uninstall the last windows update it was (2023-10 Cumulative Update for Windows 11 for x64-based Systems (KB5031358))
* flash my bios for mainboard (z690 gigabyte) to last version
* update AMD driver to last version 23.10.1
* Run windows check for system integrity see here

Since this no restart anymore.
Hope it can help
