GUIMiner - very slow Mhash/s?

[ddo]

I have an ATI Radeon 5670 and am using GUIminer but I am only getting ~1.6Mhash/s. I just noticed that in the drop down menu my video card is not being detected, but I have installed all the latest drivers. How can I get it to use my GPU?

I did prior to posting, the only solution I have found that worked for others was to reformat, but I am trying to avoid this

Try and re-install the OpenCL driver for AMD, maybe that could be the issue.

Do you notice general system slow-down when using GUIMiner?

Did you try installing the AMD Accelerated Parallel Processing (APP) SDK?

You can download amd app here http://developer.amd.com/sdks/AMDAPPSDK/downloads/Pages/default.aspx

I have reinstalled all the drivers, and installed the AMD APP SDK but it is still not detected. Do I have to config something?

I am still looking for a solution. After using GPU-Z, I see that the OpenCL option is not checked off, however I have installed and reinstalled it many times... I really want to start mining but can't figure this out!
