No its not your Graphic card problem, im sure about that 95%
Follow these Steps.
1. disconnect and check if its dusty, clean it by blowing into it. then reconnect it again.
2. if problem still occurs, Then you have to change the HDMI cable or DVI whichever you are using. Because it's damaged inside. (that's what i did)
