Sometimes the latest drivers from NVIDIA or AMD can cause issues that were not present in an older version.
While these issues are normally fixed in later revisions, it can be useful to uninstall the new driver and do a fresh install of the older working driver until these issues are resolved.
It can also be worthwhile to perform an entirely fresh installation of your current drivers, if you have updated to the latest package, but are still having problems.
There are two ways to do this:
1. Perform a clean installation using the AMD or NVIDIA installer.
NVIDIA: To do this you will need to download the NVIDIA driver you wish to install. Run the setup and select "Custom installation" then when asked, you will need to check the box to "Perform clean install". Full instructions can be found here: https://nvidia.custhelp.com/app/answers/detail/a_id/10/~/geforce-experience-driver-installation-failed.-how-do-i-manually-clean-install
AMD: You will need to uninstall the AMD Catalyst Install Manager from Programs and Features in the control panel, and then reinstall the driver version that you wish to run. Full instructions can be found here: http://support.amd.com/en-us/kb-articles/Pages/GPU57RemoveOldGraphicsDrivers.aspx
2. Use a 3rd party utility such as Display Driver Uninstaller.
