My computer has been running into BSODs over the last two days. Using event viewer and reliability monitor, I was able to track down the issue to nvlddmkm.sys. I DDU'd Nvidia drivers, and reinstalled drivers from .exe in Safe Mode. That seemed to fix the problem for a whole day.

Shut down the PC, and today, after booting normally, some 2 or 3 minutes after logging in, BSOD. When rebooting, the PC didn't "find" my Boot Drive (Crucial 1Tb NVMe). Rebooted again, was able to log in again.

Reliability monitor and event viewer show nvlddmkm.sys is the culprit again.

Sadly, despite having minidumps enabled, Windows hasn't been able to generate any.

CrystalDiskInfo shows good health for Boot Drive and my additional drives.

Please help.
