Monitor is flickering

My monitor started flickering all of the sudden. It's has some horizontal lines flicking in and out of the image. It happens now and then and is not constant. What could be the issue? I'll try to see if I can get a video of it.

I think I fixed it. I had to readjust the horizontal hold and it stopped happening.
