Hello bebe, the problem occured to your computer must be VGA driver. You can try to use driver CD driver to fix it. The driver CD is a CD that was came with your computer when you purchase it from supplyer for the first time. In side the CD, try to find a folder with a partial name ”Graphic” or ”Video”, then open it and look for a file ”Setup”. Double click the file to install driver. If u do it correctly, your problem should be resolved.
