Some windows drivers are blamed in a few crashes, but that usually means that a 3rd party driver is actually the cause.
In order to get the driver, we need to stress it out, done via driver verifier. If driver verifier finds a violation the pc will crash.
If driver verifier has found a violation and you can't get back into windows normally, try to boot into safe mode and reset in safe mode driver verifier, or in the troubleshooting options open command prompt and type verifier /reset.
