I have currently issues with my AMD Radeon R9 270x PowerColor. I have the graphics card since 2 years and I had no problems until now. Im getting a BlackScreen since 1 Week and i havent found a solution since then. Yesterday I installed Windows 10 on a new hard drive, to test if the problem is my current windows version or the graphics card. I had the same issues again. I tryed to install the newest version of the driver on my PC and at 2/3 of the installation im getting a black screen. When I restart my Computer, the logo appears and after ~15 seconds im getting a black screen again.
