William, this is rarely (but not impossible) a driver problem. It is
a usually a hardware problem.  And that limits the problem to
these three components:  the monitor, the video card, the cable
that connects the two.

The quickest and easiest troubleshooting test is to make sure
all the monitor wires are connected firmly and tightly at the monitor
and the back of the PC case.

If everything is plugged in good and tight, then next move the
monitor to a different computer (a friend or at work) to see if
the problem follows the monitor.

If it does not follow the monitor, then borrow a known good monitor
and plug it in to your pc to prove the problem is in the video card.

Good luck,
Jim Meagher
