Physical Card

• 1). Follow the monitor cable to the computer case. This is where your graphics card probably is. Go to Step 2 to find the card inside the computer.
  
  
• 2). Turn off your computer and unplug the power.
  
  
• 3). Open the case. If the monitor cable connects to a card plugged into your motherboard, you've found the graphics card. If your monitor plugs into a connector attached directly to the motherboard, you don't have a graphics card. You have a graphics adapter that is integrated into the motherboard.
