The first step to switching the graphics card is to open up the computer case. Unplug all cables and ensure that the computer is switched off. Then unscrew the screws that hold the side panels in place. Some case models do not feature a different method of opening the case; consult the handbook sent with the computer case to find the correct way to open up the case. Once the side panel is removed, continue with the next step: Removing the old graphics card.
Step 2: Removing the graphics card
Removing the graphics card is a relatively simple task. First, remove the PCI-E power cable from the card. Then continue with unscrewing the screws that keep the graphics card attached to the case. Keep these screws for later use and then continue by releasing the plastic retention switch as shown in this picture. (Insert appropriate picture here). Note that the type of retention switch differs from model to model and then gently pull the graphics card out.
Step 3: Inserting the new graphics card
This step will guide you how to install the new graphics card. Align the Graphics card with the PCI-E slot on the motherboard. Then, insert it into the slot and press gently on it until the card is completely inserted in the slot. Then, use the screws from step #2 and screw the card to the computer case. Then flip the retention switch back to the original position. These are measures to ensure that the graphics card does not fall out of the PCI slot and ultimately damaging the card during transport. The final step of this process is to close the computer case again. Slide the side panel back on and screw the screws from step 1 back into place. This concludes step 3 and the next step will be the installation of the drivers needed for the new graphics card.
