This is an easy one. When you loaded Windows it loded the standard graghics video driver. You need to use you resorce CD and load the correct driver for your video card. It should have an arrow next to it indicating the actual card that is in your machine.  After you load the correct driver it will be able to be adjusted in the display section of control panel under the settings tab.
