Locate the graphics card near the bottom-right area of the computer, just below the XPS processor cooler.

Before entering into the "guts" of the computer, make sure you have the computer powered off and unplugged. Following that, you will want to unplug any video cables, including DVI and VGA cables, that are connected to the graphics port on the back panel of the computer.

Some DVI cables may need to be unscrewed. This can simply be done by hand.
