LCD monitor shows distorted lines when I using my computer. :cry

Good evening everyone! Why are my Acer's brand LCD monitor showing distorted horizontal lines after a few minutes I am using my computer? This issue happened since last 15/5/2015. For your information, there are no tear on the monitor cables. Besides that, my graphic card (NVIDIA GeForce G210) driver was updated with the latest. I had tried removing and reinserting the monitor cables but still showing the same issue. I had also do the same with my graphic card and clean the dust but still cannot solve the issue. In order to make you people understand better my issue, I will uploading the captured video of my monitor screen.

Are the fans on graphics card working? You should be able to use MSI Afterburner to see but best to just stick your finger in the fans! :)

Can you test with another monitor, maybe even your TV should work.

Yes, it is working. Besides that, when I test my CPU with my school monitor there is no distorted lines. Is it my LCD monitor fault? or its cables or something else?

Well, if eliminating the monitor eliminates the problem, I'd say you found your problem.

Take the monitor and cable to a friend/school and try them. It may be the cable but we can't say without testing.

Thanks for you guys reply, I very appreciated those suggestion. I just replaced the old LCD monitor with the new LCD monitor that I bought just now. Finally, no more distorted lines.
