First and foremost please have a valid backup of your Hard Drive.
You can use Macrium Reflect Free to accomplish this. At the very least, create a restore point but I wouldn't rely on that alone. A backup image of the drive is best.

I have used DDU Display Driver Uninstaller to fix some serious issues with video drivers (Nvidia or AMD) and some audio (Realtek) drivers in the past. What it does is remove every remnant of the current drivers and gives you a completely clean slate regarding video or audio drivers.

Create a restore point!

You will need to run it in safe mode. How to start Safe Mode!

Some direction from the DDU site:

Recommended usage

  • You MUST disconnect your internet or completely block Windows Update when running DDU until you have re-installed your new drivers. Remember to turn Updates back on!
  • DDU should be used when having a problem uninstalling/installing a driver or when switching the GPU brand.
  • DDU should not be used every time you install a new driver unless you know what you are doing.
  • DDU will not work on a network drive. Please install in a local drive (C:, D: or else).
  • The tool can be used in normal mode but for absolute stability when using DDU, safe mode is always the best.
  • If you are using DDU in normal mode, clean, reboot, clean again, reboot.
  • Make a backup or a system restore
  • It is best to exclude the DDU folder completely from any security software to avoid issues.
