Try uninstalling then re-installing the catalyst driver, unchecking all other weird programs it tries to install (including the catalyst control center), only selecting the VGA driver if possible. Then run gpu-z to see your clocks, or afterburner to try overclocking.
Hey bob. What are the actual *required* option in the AMD catalyst package installation for mining? I was look at it last night because I'm running into some problems and it occurred to me that there seems to be a lot of fluff that comes along with the drivers and OpenCL software for Windows.
