explorer.exe ntdll.dll crash

It was deleted because of the system restore.
but as I said, all the crashes were way before I installed Valorant.
 
The latest BSOD was bugcheck 7F.
WDV was not in use at the time of the crash.


1) uninstall the Nvidia GPU driver using DDU (display driver uninstaller)
2) re-install the Nvidia GPU driver from the Nvidia website
3) make sure that you check the clean install box and if available install the physx driver.

Display Driver Uninstaller Download version 18.0.3.4 (or newer version if available)

As long as there are no performance problems or very slow boot keep adding simultaneous customized tests (goal: all except Randomized low resources simulation).
If there are performance problems or very slow boot then some simultaneous customized tests will need to be removed.

Eventhough I deleted the WDV settings
 
The BSOD bugcheck was 7E while running WDV.
The memory dump debugging displayed no misbehaving drivers.

Continue running Windows driver verifier for another 12 hours with the many customized tests.
For any BSOD upload logs.

Then turn off the tool and perform the following tests:

Run Memtest86 version 8.4 (or newer version if available) for four passes.
Repeat the test so that eight passes are performed.

In case there are any problems uploading images use share links (one drive, drop box, or google drive)

Memtest86 has a feature to produce a text report.
Please post this in addition to the images.

Please make note of the importance of temperature monitoring and aborting the test in the GPU link.
a) Record the maximum temperature and post the maximum temperature into the thread.
b) Record the test duration and post the uninterrupted test duration into the thread.
c) Aim for testing 1 hour.
d) Use the Microsoft snipping tool to post images into the thread.
