I recently upgraded my inspiron 1420 notebook to windows 7 from vista and upgraded the display drivers via the device manager. Now some of the games on my computer play in a box with a black frame around it and crash before I can start actual game play, it appears that the screen will not adjust to the size of the game so the game just tries to play in a centered window but not in a windowed mode-if that makes sense. I downloaded the display drivers I was previously using for the computer while vista was installed, however when I try to install them I am told that "This operating system is not supported. Setup will now exit." Do I need to revert back to vista in order to have everything working properly again?
