The ATi Radeon 9800 is a PCIe graphics card that was one of the most powerful of its generation. While it’s nowhere near as advanced as more recent cards, it’s still much more capable than most desktop computers’ integrated Intel graphics. Installing a new desktop graphics card isn’t for everyone, but if you’re even slightly technical, it won’t present much of a challenge. You’ll need a free PCIe slot on your computer’s motherboard and a power supply that can handle the extra load.
1. Turn your computer off. Remove all power and data cords and place it on a clean, sturdy table. Set it down so that the access panel (usually the left side) is facing up.
2. Unscrew the two or three screws holding the access panel in place. Put them in a cup or bag for later. Remove the access panel and set it aside.
3. Remove the screw holding an expansion bay slot in place. You need to select one next to the PCI-e slot (the longest of the expansion slots beneath the CPU.) Pull the slot out and set it aside.
4. Insert the Radeon card into the PCIe slot. Push down on the back, then the front of the card. Replace the screw in the expansion bay to hold it in place.
5. Plug a free 6- or 8-pin power supply cord into the card. Replace the access panel and the screws holding it in place. Return your computer to its regular spot and reattach the data and power cords. Plug the DVI or VGA cord into the new card. Turn your computer on.
