You could try enabling your integrated graphics in the motherboard's BIOS, rebooting and then running the AMD software compatibility tool to see what drivers (Adrenalin and possibly the chipset drivers) are identified. Install them, reboot to ensure everything is working, and then get back into the motherboards BIOS to again disable the integrated graphics (saving wasted power & heat).
As Albert Einstein said, "I could have done so much more with a Big Al's Computer!".
