First of all, I'm sorry for my bad English, I hope you will understand my question.
I have a Radeon HD 4860 graphic card in my desktop. I use it with Catalyst 13.1. Eveytime I start my system I have to open Catalyst Control Center, and start the fan manually. If I do not do this, the temperature goes on to hundred degrees. Catalyst said, that the fan goes on 50 percent, but it stands. If I start the fan manually, and after that, set it to automatic, it works fine. It looks like this service cannot start automaticaly when Win 8.1 starts. It's not a hardware problem, because it works fine when I do this method. Of course I tried to reinstall CCC. Do you have any idea what can I do to solve this problem?
