In order to get your switchable graphics to update... did you do the following???
1) Unistall all ATI drivers using the sweeping utilities? Then reboot and do it all again...
2) reinstall the OEM integrated drivers for the intel graphics and reboot...
3) Install the new catalyst drivers... and reboot...
4) Then what was the net step? I did all this and it didn't recognize any of my hardware after doing this method... I( was hoping you had a little insight for me...
