is aero working for you, i,e if you minimize internet explorer and hover your mouse over the task bar ie icon do you get a preview of internet explorer, if not you need to try and sort out the AMD drivers, I think I know what your problem may be, when you let windows update your graphics card drivers it kinda screws them up, to sort it you will need to unistall all ati software/drivers through programs and features in control panel, then go to device manager and unistall what drivers are there under your graphics adapter, if windows try to install again click it and cancel, before hand download 11.1a hot fix drivers so you can install after a reboot after you do the above, this should sort it out for you.
