The mainboard AsRock H61M-vs comes with its own GPU. You have to switch to external graphics in the BIOS settings, do you?
I did that but the issues persist. So far nobody has been able to give me a correct explanation. I dont know what else to do. Could you explain how to desactivate in BIOS the motherboard's integrated graphic, his GPU own. Because i switch the Video output into PCiexpress. Why does my GTX 960 give video?
Excuse me please,
but you also have to plug the monitor cable into the new graphics card.
And the correct description can be found in your handbook/manual.
The specialists for AsRock boards can be found in the AsRock Forum.

5) If the new AMD drivers installs and works correctly, delete again the C: \ AMD folder from the root directory. To save space on the HDD.
6) Enable both the Internet and Anti-Virus program (if applicable).
