Very Annoying Monitor Problem

My Samsung 955df has this VERY annoying and strange problem. It has these lines going up the screen. It is very weird, when I right click on something they will go away for a second - then come back. They look somewhat like heatlines when you see video of the African Savannah. This is my first computer that I've made myself. I have no clue what the problem is, and I hope you can help me fix it.

Thanks :D

edit: I put my monitor on 1024x768, the only time it does not have lines is at 60Hz.

Maybe it's interference of some sort? Move anything that is around it that could cause interference away from it and see if the problem goes away.

All I have are Some Creative 2.1s, even when I unplug those there is still the flickering. Anyone else have any ideas what the problem is? Do you think that I just got a bad monitor?

They could be artefacts being introduced depending on the refresh frequency that you're using. try a different one and see how that goes. Monitors are very personal things - you just have to find the right setting for you.
