When ever I try to run a game it crashes with this message, "Application blocked from accessing graphics hardware." Also, when watching videos the screen flashes green. Sometimes my screen has large flickering pixels, even though it works fine for my Xbox. This is a brand new r9 radeon 390 graphics card, and hasn't worked since I got it. Is there a way I can fix it or can I get it exchanged for a working one?
I have tried everything I can think of, even uninstalling and reinstalling graphics drivers and windows.
