    No AMD graphics driver is installed, or the AMD driver is not function


      So the other day i was trying to update my pc as i was a bit behind on updates ,so i updated everything on my pc. it was after this i encountered a problem with the driver signing saying this:


      Program Compatibility Assistant

      Windows requires a digitally signed driver.

      A recently installed program tried to install an unsigned driver. This version of Windows requires all drivers to have a valid digital signature. The driver is unavailable and the program that requires this driver might not work correctly.

      Uninstall the program or device and check the publisher's support website to get a digitally signed driver.

      Driver: ATI Radeon Kernel Mode Driver

      Service: amdkmdag

      Publisher: Advanced Micro Devices, Inc.

      Location: C:\Windows\System...\atikmdag.sys
