Your video adapter drivers probably need to be reinstalled.
Visit the support web site of the manufacturer of your computer
or video card adapter and download the latest drivers.

Before installing them, uninstall the old drivers. In your
Control Panel, open the Add or Remove Programs applet
and look for your video drivers to uninstall.

If you happen to have a notebook computer, visit the notebook
manufacturer's support website to download the correct video
adapter drivers for your specific notebook model.

After installing a fresh set of drivers, right-click on your
desktop and select Properties > Settings, change the Color
Quality to "Highest (32 bit), then adjust your Screen Resolution
to your liking, then click on Apply.

OS Name Microsoft Windows XP Home Edition

System Manufacturer VIA
System Model K7VT2
Processor x86 Family 6 Model 8 Stepping 1 AuthenticAMD ~1532 Mhz

You gave us quite a lot of information but left out 1) your video card ;
and 2) what changed between the time things worked and the time they
didn't.

I assume this is a desktop. It could be that your video card or monitor
is failing, or your video card could be overheating. Or you could just
need to update your drivers. So here are a few t-shooting steps to
take. Make one change at a time, testing after each change.

1. Update your video card drivers. Get the drivers from:
a. The card mftr.'s website; OR
b. The motherboard mftr.'s website if hardware is onboard; OR
c. The OEM's website for your specific machine if you have an OEM
computer (HP, Dell, Sony, etc.).

Read the installation instructions on the website where you get the
drivers.

2. If that doesn't help, open the computer and with it off and
unplugged, clean out any dust bunnies. Use compressed air to clean the
fans. Now run the computer open, observing all fans - particularly the
one on the video card if it has one. If you see a fan performing less
than perfectly, replace it.

3. If cleaning doesn't help and/or you can't see a fan failing, then
attach the computer to a different monitor. If the problem disappears,
then you know your original monitor is on its way out and will need to
be replaced.

4. If the problem persists with a different monitor, swap out the video
card for a known-working one. If the problem goes away, then replace
the video card.

Of course, there could be other causes but you can start here.

While it's entirely possible you have a problem with your monitor or
video card, as others have pointed out, the cause is just as likely to
be external interference (assuming you have a CRT, not LCD, monitor).

Do you have any electrical devices close to your monitor? Try moving them.

Is your monitor close to a wall that may have electrical cables running
through it? Try moving the monitor away from the wall (or window, if
applicable).

Is the video cable between computer and monitor tangled up with other
cables? Try another route for the video cable.

You say the problem is intermittent, see if you can identify a
correlation between monitor ripple and household appliance use. Moving
the monitor or appliances to another circuit may help.

I added a second monitor to my PC, and at first I thought I wasn't going
to be able to run them side-by-side because there was ripple on the
first monitor whenever the second one was turned on - unless I moved it
a foot away. A sheet of steel, connected to ground and installed between
the monitors, solved the problem.

Thank you so much for your help. The rippling has stopped! I downloaded
new video drivers and so far it seems to have helped. I have quite an
old monitor and I have just purchased a new lcd one which is on its way
to me so hopefully that will be the end of it.

Many thanks again.
