So i recently bought Battlefiled 4 and i head the stable drivers(13.9) for my HD6850
But my PC keept crashing because of bad_pool_caller error on windows 8.
I read in the BF4 forums that i head to update my drivers to the latest beta.
So i did that and just installed the beta driver without removing the previus one.
I noticed it didn't work so i removed everything(with CCC Remove all wizard).
Then reinstalled only beta driver, i was getting "load mmdriver application has stopped working" and "Catalyst control centre:Host application has stopped working" error.
Now i removed the beta driver and installed the stable version 13.9.
Result: CCC doesn't detect my card
