Newer motherboards do not have AGP slots.
The AGP, or Accelerated Graphics Port, was designed to replace the PCI (Peripheral Component Interconnect) interface for graphics applications. The PCI is a general interface used to connect various types of components. AGP is faster than PCI and dedicated to video applications. AGP has been phased out in favor of PCI-Express, but there are still AGP cards available for users who need to upgrade older graphics cards.
Instructions
Access
1. Uninstall the display driver for the video card that is being replaced by accessing the Control Panel through the Start Menu. Find the Device Manager. If it's not available as a Control Menu option, click "Hardware and sound". Expand the Display adapter menu by clicking the "plus" (+) sign, right-clicking on the model of video card installed on your computer and selecting "Uninstall".
2. Turn off your computer and disconnect all wires.
3. Open the computer case.
4. Electrically ground yourself with a an electrostatic discharge (EDS) wrist strap that attaches to the computer case. An ESD strap is the most effective method, but if you don't have one, you can also ground yourself by touching a bare metal section of the computer case.
Replace
5. Remove the old AGP card by unscrewing the retaining screw at the back of the case and pulling the card up out of its slot. There may be a small retaining clip that may have to be disengaged from the old card. If the old card required external power, make sure to remove the power connector.
6. Install the new card by sliding it into the slot. Secure any retaining clips and reinstall the screw at the back of the case to secure the card. Plug in the power connector to an connector from the computer's power supply if needed.
7. Close the case and reconnect all wires.
Drivers
8. Turn the computer on.
9. Cancel any automatic installation that your operating system may initiate.
10. You can find drivers at the graphics card manufacturer's website.
Install the display drivers from the installation disk supplied with the new graphics card or visit the manufacturer's website to download and install the latest drivers.
