To update the graphics driver, simply go to Start > Run and type dxdiag. Wait for the window to load and then switch to Display tab. Note the model of your video card and paste it on Google. The first site should be the manufacturer's. Browse to that site and download the latest driver available for your model. You will need to use a drop down menu to select the graphic card. If you're using a laptop, the drivers are located on the laptop's manufacturer website.
