This is what i'd try..

1) uninstall CCC
2) run http://treexy.com/products/driver-fusion to completely remove the residuals
3) run chastity's crap cleaner http://rog.asus.com/forum/showthread.php?8981-ATI-Crap-Cleaner&s=1a5f8be396320ee3b9b036e485634b51
4) reboot
5) re-install CCC i've had the least problems with the 12.10 driver, though no problems with 13 on this machine
