How to remove or replace a GPU(Graphics
Processing Unit)
|
So, today I’m going to explain the basic proceedures of how to remove or replace a GPU (Graphics processing unit).
The only tool I required was a philips screwdriver. However you might need different tools, so check what tools you need before you start.
Step 1: Unplug your PC from the mains power supply (plug). Do not remove the cover on the pc, with it plugged in the mains.
Step 2: Remove side cover retaining screws
Step 3: Keep your finger on the power button on your computer tower to remove any static electricity from within the computer.
2 or 3 seconds will be enough.
Step 4: Now you have removed the side cover. Touch your hands on some of the main components inside the pc. This will extract any static electricity within the pc and your body. This is done so you don’t damage any of the components through static electricity.
Step 5: Locate and remove the GPU.
Point to note! There are two types of Graphics cards, one being AGP. Which stands for Accelerated graphics unit, which is fitted on older motherboards, The other one is PCI Express x16 which is fitted in newer motherboards.
In this illustration it is a PCI Express x16 slot on the motherboard.
My GPU is PCI Express x16, you need to check this prior to the replacement as the two are not compatible.
Modern GPU’s are extremely powerful as they display a lot of graphics, therefore they require a lot of power, in this instance my power supply is an iCute 1000 watt, which is sufficiently powerful enough to drive two of these cards. Also before we continue, GPU’s get extremely hot when gaming or processing therefore, my advice would be to have a PC case that will provide sufficient ventilation through system fans.
If the GPU gets too hot it will burn itself out, (it will melt). As you know they are not cheap to replace.
Step 6: Fit the card and make sure it is correctly seated.
Replace retaining screws.
Step 7: Connect power cables into your GPU.
Step 8: Reconnect any other cables you may have removed while removing and replacing your GPU.
Step 9: Refit side panel and reconnect your PC to the mains.
Step 10: Turn your PC on.
Point to note! When your computer has started and you’re on the main windows screen, windows will automatically install the basic drivers for your GPU through windows update. If you have a CD that came with your GPU, put that in your CD rom and follow instructions, that will install the software and drivers needed.
If you don’t have a CD, go to the makers website and download and install the latest drivers.
Here are a couple of links to gpu driver downloads.

Remember If carried out correctly this is a very easy task, if at anytime you are unsure, do not continue and seek help and advice.
