Video card.
The Gateway 300 LE is a desktop computer equipped with a 1.2 GHz Celeron processor, 512 MB of DDR memory and 20 GB of storage space. If your system's performance suffers when running certain graphics-intensive applications, such as computer games, you may benefit from installing a new video card in one of the computer's available PCI slots. The process is not overly complicated and you should be able to have your machine back up and running in a matter of minutes.
Instructions
1. Shut down your computer. Examine the computer's ports and disconnect any attached cables, including the power cord. Press the power button to discharge any stored electricity. Ground yourself by touching the exposed metal on the rear of the computer.
2. Move the computer to a clean, well lit work area and examine the rear panel. Locate and remove the thumbscrews that secure the side panel in place. Slide the side panel towards the rear edge of the computer, then lift it free of the case.
3. Place the computer on its side and examine the motherboard. Locate an unused PCI slot and find the adjacent slot cover. Remove the screw securing the slot cover in place. Remove the slot cover but keep the screw nearby for later use.
4. Insert your video card into the PCI slot and apply pressure until it is fully seated. Use the screw you removed from the slot cover to secure the video card's metal bracket to the computer case. If necessary, connect one of the cables from the computer's power supply to the appropriate port on your video card. Not all models of video card require additional power.
5. Replace the side panel and use the previously removed thumbscrews to secure it back in place. Return the computer to its original location. Connect your monitor to the appropriate port on the newly-installed video card. Connect the rest of the previously-disconnect cables. Turn on your computer and log into Windows.
6. Open your computer's optical drive and insert the installation disc that came packaged with your video card. Wait for the installer application to launch. In some cases, you may need to browse the disc's contents and launch the installer manually. Follow the onscreen instructions.
7. Open the "Start" menu and select the option labeled "Control Panel." Open the "Displays" control panel. Navigate to the tab labeled "Settings" and adjust the display resolution as desired.
