The basic principle of the graphics card is that it is your computer's display. It receives text and graphics from your programs and sends them to your computer display screen. A graphics card problem will display the result on your screen, sometimes making it difficult for you to separate the two. If your screen flickers, it means that the video is not being displayed. In 3D view, you will see spots, green squares, and flashing lines interspersed with black areas. One of the components of the screen or the graphics card will fail in any case.
The screen must be excluded from the equation. This can only be done by isolating the screen from the other elements. You can choose which one, but it's easier to connect to another screen than to swap a graphics card. If you only have one monitor, borrow it and connect it to the computer. This method is compatible with most laptops including the mac if you have the correct connections. Do display problems persist? If so, the problem is with the graphics card. If not, it's with the screen.
Troubleshoot a problem with your graphics card
Consider updating before you embark on any major tasks. An issue with your graphics card driver can cause problems. Open the Windows “Start” menu. Click on “Computer“, then “Properties“, and finally “System.” Select “Device Manager” from the “Hardware tab.” Double-click your name in the “Graphics Card” section. You will see the version in the “Driver Tab“. You can check the manufacturer's site to see if it is the most current or download the latest. It should also be compatible with your operating system version.
How to change the graphics card
If the display is not working properly, it's time to replace the graphics card. You can change a component with minimal effort, but it is a simple process. It is the most difficult step to make sure you choose the correct graphic card part. Consider whether you require more power or more memory. You can still buy a similar card but a new one with 100% compatibility.
