Display Screen showing Disorted colors

[Demetrius]

The display screen of my computer system does not show true colors.
Instead of black background, it shows green color and also pink color in place of some other colors.

What could be the reason? please help.

It seems that the connection is loose between the video card and the computer screen because of which you are not getting true colors.

-Turn off your computer and check the video-card whether it is properly fixed.

-Shake the video-card in its slot and restart the computer.

It is the issue of the bad video-card.You can troubleshoot a video card by following the below steps.

Reset the video card

If your video card is not an on-board video card verify that your video card is not loose by removing the video card from the computer and then re-inserting the video card back into the same slot from where it was removed.

Exchange video

If reseting the video card has not resolved the issue or your video card is on-board and you have access to another known working video card. Try an alternative video card in the computer.

Replace video card

If an alternative video card did work or you do not have an alternative video card to try,then purchase a new video card to replace the defective video card in the computer.

If an alternative video card didn't work replacing the video card with a new video card will not resolve the issue it's likely a defective motherboard and should be replaced.

Replace motherboard

If all the above steps have not resolved the issue it's a bad motherboard.
