Is there a specific explanation for why CCC refuses to allow crossfire to be enabled? The option is there but as soon as we click apply it reverts back to disabled instantly.
Try to perform clean install using Official WHQL Catalyst 12.1. Link in sig.
If that doesn't fix it, might want to try in different motherboard. The PCIe-Chipset might have gone bad.
Or Driver Sweeper might have whacked other chipset drivers for the motherboard. Update chipset drivers and repair Windows.
Also, never use the Auto Update function.
