Welcome to TSF, Hakan.
First step: go to the AMD website and download the latest drivers for your CPU. This problem sometimes happens when dual-core CPU's are used and the drivers haven't been installed.
If that doesn't help, follow each of the steps in Common Game Issues in my signature, and post back with results (and full system specs if the problem persists).
