• 1). Turn off your computer. Remove all power and data cables and place it on a clean, sturdy table. Set the computer down with the access panel (usually the left side) facing up.
  
  
• 2). Use your Phillips screwdriver to remove the two or three screws holding the access panel in place on the back of the computer. Remove any power or data cables obscuring your view of the PCI-E motherboard slots. Remember their location for re-insertion later.

• 4). Install the six- or eight-pin power connector from your power supply if the card requires it. Replace any power or data cables you removed in Step 2. Replace the access panel and screw it into place.
  
  
• 5). Place your computer in its usual spot and reattach all power and data cables. Plug the monitor DVI or VGA cable into the graphics card. Turn on your computer.
