Adept I

I had Windows 11 Pro installed, and even with a Fresh re-install I continued to have the same problem as you.
CPU: AMD 5800x Ryzen 7
Motherboard: ASUS ROG STRIX B-550-F-Gaming WIFI

It seems the majority of people I have read with these crashes also have the same AMD CPU.



The combination of returning to Windows 10, disabling TPM and using the Windows 10 specific chipset and bios drivers from the motherboard manufacture has fixed this for me now.


Let me know how this works for you.


May I ask, which motherboard you have? I have used both AM4 and AM5 motherboards, assembled multiple machines with AM4 platform and not run into this problem once.

I use real Windows licenses, not one of those ten dollar ones.

I have fTPM enabled, Windows UEFI boot setting, virtualization enabled. I have not disabled password query (disabling it is not a good idea, but neither is running your machine with an admin account, like so many do)
