Since Windows uses drivers to work with your hardware devices like display, motherboard, network card and so on.

The majority of display problems are related with video card drivers, such as missing, incorrect, corrupted drivers.

Hardware failure, incorrect installation and external factors also caused video problems.

If you have just installed Windows or have changed your video card and are experiencing problems, the most likely cause is a missing or incorrect video driver.

Most video cards will come with a disk that contains drivers and other software. So before you install it, check the information that came with the video card to be sure it supports your current Windows version.
