I have the 7500 All - In - Wonder installed in a 1 GHz HP Pavilion 8776C and the game works fine. Because of some bad advice I received from activision while trying to make Medieval Total War work (which it won't with our drivers), my machine crashed and I had to reload the driver that came with the 7500 installation CD. Since everything I wanted - other than Total War - worked with this I never went back and got the updates. If you are running a newer driver than your installation CD driver, you might want to try that one.
