If no error is found in the test.
Try forcing Windows to show failed drivers and produce minidump files, enable Driver Verifier for this;
Let the BSOD happen 3 times and then see if the files were created.
Before running Driver Verifier, create a new system restore point.
If you have problems starting Windows after enabling Driver Verifier, follow these steps:
Start your PC, as soon as Windows tries to load (spinning dots appear), press and hold the power button for 5 to 10 seconds to perform a forced shutdown
Do this two or three times.
Windows will boot into the Recovery Environment.
Go to Troubleshoot > Advanced Option > Startup Settings and click Restart.
When restarting, press 4 to enter safe mode.
Open command prompt as administrator, run these two commands and restart your PC.
