    how should i fix 'application has been blocked from accessing graphics hardware' error for overwatch?


      I am normally able to play 2-3 games before the crash happens, and then the game freezes (sound keeps going for a bit) and to stop the crash i have to close overwatch via task manager. Another error message that appears is "Drivers have stopped responding and recovered".

      I have already contacted blizzard, updated my drivers, and tried every other solution i can find online, so looking for a more amd-specific thing that will solve the problem for good.

      Attaching dxdiag for reference

          This error message you have described is caused by a display driver crash. I would recommend trying the steps below and performing a clean installation of our latest Crimson 16.6.2 drivers.


          1. Run the Windows self check tool to check scan and automatically repair any corrupt files found in Windows. There is a guide on how to do it here.  What you need to do is run an elevated command prompt (elevated means run it as administrator) and type SFC /SCANNOW. This will generate a statement indicating if errors were found the Operating system and if they were fixable.


          2. Make sure you have installed Microsfot NetFramework and Visual C++ 2013. These should be installed already, but they can become damaged, need repairing or reinstalling.


          3. Update Windows. Install all available critical, recommended and optional updates. Often Netframework and Visual C are included in the recommended or optional updates Windows provides. Windows should always be fully up to date before installing our drivers!


          4. Use DDU to sweep the system of AMD drivers in safe mode.


          5. Install the latest Crimson 16.6.2 drivers once the above is completed and check to see if the issue is resolved.
