The proper instalation of the video adapter driver under windows:
1. Either from Control Panel -> Display or Desktop Right Mouse Click -> Option, Display. Go to adapter and update driver. Following prompts select Standard VGA. Restart computer. Now, make sure that old drivers (non windows vga) are deleted from your system completely. Once that done, repeat the procedure this time selecting the drivers you wanted to install. It will prompt for restart. After restart try new settings.
What kind of video card you have?
Good luck
