Also, I had a radio interference problem when I first setup X ... you
should try changing the vertical and horizontal frequencies -- If your
situation only occurs in X, and not in a text based console, DOS, or
Windows, it is probably some type radio interference.
You may want to check the electrical wiring too. Make sure that the
monitor cables aren't near power cables or any poorly insulated wires.
I hope this information will help more than the UFO theory!
