Please help analyze a minidump

Question

(I didn't find a more appropriate tag for my question, sorry)

As my Windows 10 Pro crashed several times with a blue screen, last time with "critical process died", I managed to open minidump, but have no idea how to interpret its result and what to do now. Here is a full copy of it. Note that I had run preboot (looong) memory checks as well as disk checks, no error found.

Thanks for any help!

Hi, the information you have provided indicates a problem with the system kernel, usually caused by a driver, which we need to verify further. Please first create a restore point for your system, then please refer to this article: https://learn.microsoft.com/en-us/windows-hardware/drivers/devtest/driver-verifier to enable driver verifier. In the third step select "Automatically select all drivers installed on this computer", wait for a couple of new blue screens and then collect 2-3 new dump files and share the new dump files with me.

If the computer has any automatic overclocking features enabled (including XMP, EXPO, etc.) or manual overclocking, please restore the defaults first.

Driver verifier puts heavy pressure on the drivers in your system to troubleshoot drivers that are in poor condition or misbehaving. It is normal for your computer to run slowly after driver verifier is turned on. The computer will also crash more frequently and generate dump files during this process.

If your system fails to boot after driver verifier is turned on or enough dump files are generated, please restore via the restore point.
