Hi, i hope i can find help.
My problem is when i try to crossfire my R9 280x with a HD7950. If no display driver is install, the PC can boot on windows 10 and i can see both card
in devices manager. But if i install any drivers (crimson or catalyst) the pc freeze when "install Display Driver" and i have to shut down the computer.
After reboot, the pc load windows and when it enter my session the screen goes black.
So, i think it's definitly a driver issue but if anyone have the same configuration and was able to get it to work.
