After using Display Driver Unistaller and installing the AMD 15.6 beta drivers, I get random black screens after using my computer for about an hour, or attempting to use the graphics card for GPU intensive games or programs. The computer is still running, as sounds from videos or games continue to play as if nothing has happened, but my monitor is just completely black, and the image does not return, and I get no message on my monitor such as “Check signal source” or “Cable not attached”.

I had a AMD Radeon HD 7750 installed before the R9 290, but as I stated in the original post, I have completely reformatted both my hard drives and reinstalled windows since I installed my new card. Windows is also completely up to date.
