I just installed Windows 7 on a Dell Optiplex 760L and the display is not shown correctly.

Windows 7 automatically installed "Generic PnP Monitor on Standard VGA Graphics Adapter Display" and the only resolution available is 640x480.

I went to the Dell website and noticed that there were no drivers for Windows 7 for this computer.

Do you guys/girls have any suggestions on what I can do so that display is shown correctly on this dell computer with Windows 7? Really appreciate your help.
