Please help.. my monitor is jiggling.. I can't think of a word to describe it.. it's like a horizontal motion that goes up and down my screen.. give me a headache looking at the monitor. what can I do to fix this? I just started doing this. Is it time for a new computer?

Check out any radiation-emitting devices around the monitor like speakers, microwave, TV, etc.
