Can You Put a New Graphics Card in an Old Computer?
Here’s how to upgrade a graphics card and give new life to your gaming PC.
What to Know Before Buying a Graphics Card Upgrade
You should verify a graphics card upgrade is compatible with your computer before you make a purchase. Here’s what to consider before you get started. Most graphics cards are secured by a screw that holds the rear of the card to the back of the case and a lever found on the PCI-e slot itself. Remove the screw and press the lever, then gently remove the card. Modern video cards don’t come with drivers in the box. You should download and install drivers from the company that makes the GPU on your upgraded graphics card, which, in almost all cases, will be AMD or Nvidia.
Will the upgrade physically fit inside your computer? Measure the interior of your PC and compare it to the dimensions of the graphics card you want. Does your PC have a compatible PCI-e x16 slot? Most PCs with a graphics card installed have this slot, but it’s important to verify by opening your PC. Can your PC’s power supply handle a graphics card upgrade? All graphics cards will list a minimum recommended power supply wattage. The wattage of your PC’s power supply is on its label. Does your PC’s power supply have the required power connectors? Modern graphics cards use one or more PCI-e power connectors listed in the card’s specifications.
As the saying goes, “measure twice, cut once.” Double-check these points. There’s nothing worse than discovering your new graphics card isn’t compatible with your PC. Graphics cards are especially prone to this because of their size and power requirements.
Troubleshooting Graphics Card Issues
If your PC is now working with the upgraded graphics card installed, you’re finished. Enjoy the new card’s power! Should you encounter problems, however, these fixes could resolve the issue.
