I have a notebook with integrated and dedicated graphics card. I've reinstalled the system recently and tried to install driver for dedicated card (and integrated as well). The AMD self recognizing program had installed the driver (at least it seems like it did), but the card doesn't seem to know about the driver. To be more specific, when I disable the integrated card in Device Manager, everything behaves like without driver (I mean lowest resolution, no aero, etc.) I consider myself as quite experienced user, have never faced this problem though.
