Option 1. Remove the conflicting driver

In most cases, correcting this error is usually sufficient to determine the faulty driver and uninstall it (or upload the more recent and stable version). Typically, the name of the problematic drivers mentioned on the blue screen how to error, you need to find and remove.

DEL /F /S /Q /A "D:\Windows\System32\drivers\Driver"

Instead of D:\, you can put down the name of the other partition (if the system is on it), and instead of the DRIVER is the name of your driver that was specified in the blue screen (for example, example.sys). Press Enter, and after the process, restart your PC.
