Is there another monitor in the immediate vicinity?

If so, move it.  I've seen this occur when two systems and monitors are
placed "too close" together.  It's a problem with EMI interferance between
the two systems.

Check the power supply as well for ripple, and in addition check the WALL
for 120V power.  Low voltage will sometimes cause this.
