Next, select Display Adapters, choose your graphics hardware from the list, then finally right-click choose Uninstall Device. Once the driver is uninstalled restart your computer and Windows will automatically re-download the latest version when you log back in. Alternatively, you can visit your Graphics hardware manufacturer's website and download the latest drivers.
