Sometimes when configuring your graphics cards for a GPU cryptocurrency mining rig, things can go awry. Maybe you installed a driver that’s making your mining software crash. Maybe you accidentally updated drivers to a newer version that — for one reason or another — gets a lower hashrate than you got before. Whatever the case may be, it’s almost certain that at some point in your cryptocurrency mining journey that you will want to do a clean uninstall of all graphics cards drivers so you can start over.
Display Driver Uninstaller
Thankfully, there’s a handy and free Windows application that can do a full and complete uninstall of any graphics card drivers you have installed on your PC. It’s called Display Driver Uninstaller (DDU for short), and you can download it from the Guru3D website. It works with both AMD and Nvidia GPUs.
Uninstall and restart, keep the same GPUs
When you launch the application, you’ll see a window that looks a lot like what you see below. The program detects which version of Windows you’re running, and lets you choose which graphics drivers you want to uninstall — either AMD or Nvidia.
From there, all you do is click the “Clean and restart” option. Obviously this is the most recommended option because it will prevent weirdness that might happen from the process of uninstalling your drivers. Giving it a full reboot will let Windows load up with the stock video drivers and allow you to install new ones.
Uninstall, and change GPUs
Alternatively, you can choose to “Clean and Shutdown,” which is ideal for installing a new graphics card. This way, the program will do a clean uninstall of all drivers and simply shut down your system, allowing you to swap out your GPU hardware. While this isn’t usually necessary when changing hardware, it can be helpful if you started having problems with your display or mining software.
