Not only can installing a video card be very rewarding, it can also be beneficial to the performance of your computer. Before you can upgrade a video card, you must find out what type of video card (also referred to as a "graphics card") your motherboard supports. There are two primary kinds of video cards: AGP and PCI-E. As of 2006, AGP has been phased out in favor of the infinitely faster PCI-E. Older computers may be limited to AGP, while computers purchased after 2006 may support PCI-E. You will need to consult your motherboard documentation to find out the specifics of your motherboard compatibility.
Instructions
1. Unplug all of the wires connected to the back of your computer case. Press the power switch on power supply to turn the power off (it should be in the " - "position). Use your screwdriver to unscrew the row of screws on the side case panel. You only need to remove the case panel that grants access to the motherboard. If you can't tell by looking which is the right panel, you will have to remove them both. Some cases make this harder or easier to tell. Also, some modern computer cases are "tool-less" designs that don't require a screwdriver. You can use your fingers to unscrew the plastic screws.
2. Place the case on its back with the motherboard facing you. Place both hands on the metal structure inside the case. This will eliminate any static buildup that could harm the computer and the video card. Do this often when working inside the computer case.
3. Locate the video card slot. On most motherboards, the PCI-E and AGP slot are near the middle-bottom of the motherboard. The slot is usually colored, labeled (use your flashlight) and place above a row of basic PCI slots (bland, small white slots).
4. Raise the card holders on both sides of the PCI-E or AGP slot. The card holders are used to hold the card into place when your case is vertical. If one is present, remove the old video card. Toggle the card, but do not pull. Gentle force should be applied on both ends of the card until it lifts.
5. Insert the video card. Align the card with the connectors in the slot and gently press the card down firmly into the slot. When the card is firmly in the slot, lower the card holders on both ends. Attach the appropriate power supply connected into the side of the video card. You will need to refer to the video card documentation to see how much power is required.
6. Replace the case as it was. Reconnect everything. Turn the computer on. You will need to upgrade the drivers for the newly installed video card. Get the most up-to-date drivers for your type of video card (which would be NVIDIA or ATI) from the "Resources" section below.
