Today i received new ram, and i've installed it
but when i restarted my computer, there were this message "No amd graphic driver is installed or the amd driver is not fonctionning properly. Please install the amd driver appropriate for your amd hardware."
I've got a HD7870 and a HD7850 in crossfire
I uninstalled many times the driver, and reinstalled
And my computer was still showing this message. By the way, only one of my two screens works.
Then, i've unplugged the HD7850, started the pc, and everything was okay
Shuted down, plug the HD7850, put the crossfire bridge
BUT i've reactivated the crossifire, and then it did it again, still the same message, with only one screen working...
I don't know what trying, have u got an idea ?
