I have a Toshiba Satellite L655-s511. I had to format the hard drive and reinstall windows 7. Now wimdows does not recognize my graphics card which is ATI Radeon Mobility hd 5650. Under the display adapters tab in device manager all i can see is "standard VGA graphics adapter". I have tried installing latest driver using AMD catalyst but all drivers install except for the display one. I had dropped my laptop before this. Could it be a hardware problem?
