Hello... make sure you have a Windows driver installed in the device manager... and see if it is enabled... Make sure it is Enabled to boot first in your BIO's...
Everything is already installed and i could even find it on catalyst control center.
Both are AMD card HD7520G and 7600M. Only the HD7520G works.
My HD7520G shows it has a memory of 512MB in GPU Z but 7600M series shows it has 5701722MB... WTF??
