Every tut I have ever read, including AMD, instructs you to remove all instances of the previous card before installing a new one. Common sense. Try this, download the correct 11.11 driver suite for your mobility driver and save. (Don't use 'automatic find and install'). Download DriverSweeper http://phyxion.net/Driver-Sweeper/Driver-Sweeper/ and save. Computer control panel > uninstall a program > amd install manager..express uninstall including install manager > reboot > run driver sweeper, select amd display...delete all it finds > reboot. Install new 11.11 driver suite. Reboot
