Install two video cards on your computer.
Video cards allow you to play video games, watch movies and connect monitors to your computer. Although most computers use one video card, you may find two different cards that excel in different aspects of the computing world. One, for example, might be better for playing video games, while another card has multiple monitor connections. For this reason, you may want to install two different video cards on your computer.
Instructions
1. Power down the computer. Disconnect all of the cables and remove the Phillips screws on the back of your computer with a Phillips screwdriver. Slide open the case to expose the interior of the computer.
2. Locate the PCI card slots on the back side of the motherboard (the large computer board in the middle of the computer). The PCI slots are typically horizontal yellow strips that hardware cards connect to.
3. Slide the first video card into one of the available PCI card slots. Once it is in place, push down on the small locking levers found to the side of the PCI slot. These lock the card into place so it does not fall out.
4. Repeat the process with the second video card. Close up the computer case, reattach the cables and tighten up the screws.
5. Power on the computer and insert the first video card's installation CD. Once the driver installation wizard loads, follow the short prompts to install the drivers. Eject the first CD. Insert the second CD for the second video card. Follow the same prompts to install the drivers and complete the installation.
