1. Power off and unplug the computer.**
Before opening the computer case, make sure that it is powered off and unplugged from the power outlet.
2. Open the computer case.**
Locate the screws that hold the computer case closed and remove them. Then, carefully slide the case open.
3. Locate the video card.**
The video card is usually located in a PCI Express slot on the motherboard. It is a long, thin card with a fan and a number of ports on the back.
4. Remove the video card.**
To remove the video card, first remove the screws that hold it in place. Then, carefully grasp the card by the edges and pull it straight out of the slot.
5. Inspect the chips on the video card.**
Look at the chips on the video card to make sure that they are properly seated in their sockets. The chips should be flat and evenly spaced. If a chip is not seated properly, it may be loose or tilted.
6. Reseat the chips.**
If a chip is not seated properly, you can gently reseat it by pressing it down into its socket. Make sure that the chip is flat and evenly spaced with the other chips.
7. Reinstall the video card.**
Once you have reseated the chips, reinstall the video card in the computer case. Secure it in place with the screws that you removed earlier.
8. Close the computer case and power on the computer.**
Once the video card is reinstalled, close the computer case and power on the computer. If the chips were not properly seated, you should now see a normal display on your monitor.
If you are still having problems with your video card, you may need to replace it.
