Driver Sweeper is a fast tool to remove driver leftovers from your system. Driver Sweeper is very easy to use. You only have to select the drivers you want to clean.
The best way to clean drivers is to first uninstall the drivers using the official uninstallers, reboot in Safe Mode and run Guru3D - Driver Sweeper. However, rebooting and not going into Safe Mode also works, but can cause some files not to be cleaned.
