You must update your video drivers. Go to the manufacturer's web-site, then to the download section. Search for the model number of your video card. If you are not sure what type of graphics card you have, you can find out by going to the following location: right-click "My Computer" -> left-click "Properties" -> left-click "Device Manager" -> left-click the plus next to "Display Adapters". The named device under display adapters is the manufacturer and model of your graphics card. This will generally solve the problem. If this doesn't solve your problem you must get a graphics card (not an onboard graphics controller) that meets the specifications for the software that you are using (check the back of the cd case).
