Recently upgraded to WIN 7 Home Premium 32-bit from Vista. Tried to run a game, and game will not recognize card. Ran DXDIAG, and Display Graphics shows as Standard VGA Adapter. System : VGN-AR520E Graphics: NVIDIA GeForce 8400M GT Tried installing drivers off Sony's site, but they are all Vista Drivers. Sony does not plan on adding any WIN 7 drivers for this graphics card. Tried installing Driver off of Nvidia's site, but did not recognize compatible hardware. Any next steps to get this fixed would be appreciated. Sony support basically told me to go back to Vista and this is my only option.
