Application to Mod the driver so the system accepts it
->
http://www.driverhea...ol/download.php1) Disconnect from internet so windows dosen't automatically installs a driver itself;
2) Go to Add/remove programs and uninstall Catalyst Control Center;
3) Go to Device Manager and Uninstall your Graphics Card (put the mark where it says to remove all of the software);
4) Reboot your Laptop.
5) Install MobilityModder (Follow instructions on Mobbility Modder Website if you dont know how to use it)
6) Run the driver file and let it extract to C:\Ati\support\9-3_vista32_win7_32_dd\, after it extracts close the New Installation window.
7) Open MobilityModder and browse to the folder where it extracted the driver i supposed its C:\Ati\support\9-3_vista32_win7_32_dd\ .
8 ) Click Modify;
9) After its done, close MobilityModder and go to C:\Ati\support\9-3_vista32_win7_32_dd\ and click setup;
10 Let it install and if it says that the driver is not verified click on install it anyway.
11) Reboot again and be amazed, at least i was!
