Could you please run the diagonistics on the computer?
Turn on the computer. When the DELL logo appears, press <F12> immediately. Select Diagnostics from the boot menu and press <Enter>.
NOTE: If you wait too long and the operating system logo appears, continue to wait until you see the
Microsoft Windows desktop. Then shut down your computer and try again.
b Press and hold the <Fn> key while powering the system on.

Make a note of any errors that you get after running the diagnositcs on the computer.

The ATI website may or may not have that particular driver on it (I can't remember). However, I would first try the manufacturer's website (i.e. Dell, Gateway, HP). If neither of those have the driver you are looking for, try this: http://www.softwarepatch.com/utilities/mobility-radeon.html
