AMD Graphics Issue in Skyrim

I hope this is the right place for this and not under PC Gaming. I have been have an HP Pavillion dv7-4285dx, Intel Core i5, 6 GB RAM, ATI Mobility Radeon HD 6370 and I am having an issue with graphics in Skyrim.

I am seeing large irregular shapes and/or stretching of textures. I have been trying to read about this and as best I could figure I was needing to update the ATI drivers or the ATI Catalyst control for the switchable graphics. I tried updating the drivers through ATI but the automated tool that finds what you need essentially said to contact the manufacturer. HP's auto drivers/bios update tool said I didn't need anything.

Previously I had attempted to download an updated Catalyst Controls. That initially seemed to fix everything, Skyrim looked good and I retained control of the switchable graphics. Everything was great until the computer crashed and I lost control of the switchable graphics completely and the issue in Skyrim returned. Then I got some (very surprising) help from HP via a crash report and was able to eventually re-install the original ATI Catalyst Control and now I am back at square one.

Please help!
