AGP slot was the standard for graphics card interface with the motherboard. As technology advances, the newer PCI-Express has taken over and many graphics card nowadays use PCI-E slot as its interface with the motherboard.
Before you can install the graphics card, you need to identify which type of slot does your graphics card uses.
If you are not sure which slot does your graphics card use, check out the user manual that comes with the graphics card.
Once you are ready to install your graphics card, follow these four steps...
Step 1: Uninstall the current graphics card drivers
Before you install your new card, you have to uninstall your current card driver. This is because the current driver might not be compatible with the new graphics card and it might result in hardware conflict.
On your Windows desktop, click 'Start' -> 'Control Panel'. In the new window that pops up, search for the 'System' icon and double click on it. Look for the 'hardware' tab. Click on the 'Device Manager'. This will pop up a new window showing your entire hardware configuration. Your graphics card should be listed under the 'Display Adapter' heading. Double-click the name of your graphics card. In the next window, go to 'Driver' tab and right below, there is an 'Uninstall' button. Click the Uninstall button. Once it is done, close all the windows and shut down your computer.
Step 2: Remove old graphics card
Now, unplug the power socket from the wall and remove the casing of your computer. Locate the AGP slot (short brown color slot above the rows of long white PCI slot) with your old graphics card. To prevent static charge from damaging your computer parts, touch a metal part of the case to ground yourself. Remove the screw on the back plate of the graphics card and unplug the graphics card from the slot.
Step 3: Install new card.
Align the new card correctly with the AGP slot (align with the PCI-e slot if your graphics card is of the PCI express type). Applying even forces on both end of the card, slowly push the new graphics card into the slot. Secure it to the back plate with a screw.
Step 4: Install new drivers.
Plug in all cables and boot up your Windows. Your operating system should now automatically recognize the new hardware and walk you through the installation wizard. Most of the time, you will need to insert the driver CD that come with the graphics card into the CD-ROM. Locate the 'setup.exe' file in the driver CD and double click on it. It will then walk you through the installation process. If your graphics card is not the latest model, then most probably there is a newer version of the driver on the Internet. Check out the manufacturer's website and download the latest drivers. Install it. Once done, reboot your PC. Now, you're ready to start gaming.
