You have a driver clash between something and CCC. Also, did you install AMD SDK?
 If this is a dedicated mining rig you need to fresh install, then mobo drivers with no bloatware, then net 4 framework, then CCC, then amd sdk, then msi afterburner as trixx actually is lame, then cg miner.
If this is not a dedicated rig, you have to find what program is crashing the overclock drivers. There is no easy way except a fresh install.
