I have Gateway NV53 nootebook and I just reinstalled my windows 7 .
Before the reinstal I had display adapter - AMD M880G with ATI Mobility Radeon HD 4200 like this -
After I reinstalled the windows 7 I installed the VGA package from the above link of Gateway site and I now just see the Standard VGA Graphics Adapter under display adapter -
How could I install this VGA ?
Finally I downloaded AMD Driver Autodetect and it detected graphics hardware - Mobility Radeon HD 4xxx Series , I downloaded to appropriate driver and it worked out .
