Monitor Faulty

My monitor display keeps on cutting out.  When it cuts out the monitor light goes from green to yellow.  However when I pull out the cable at the main unit the light goes back to green.  This seems to indicate that the monitor is ok.  Is this a problem with the video card?

You overclocking?

try these
Make  sure you have the latest drivers for your video card.
Make sure you're running the latest version of DirectX
Disable fast writes in the BIOS
Up the AGP voltage ONE CLICK
Disable write combining in the Trouble shooting part of Advanced Display Settings.
Reduce the AGP rate to 4x

Does this only happen under heacy CPU load? 3D gaming, etc?

I have tried two of the things you suggested.  Latest Driver and I have disabled write combining.  My Bios does not seem  to have the settings for the other two but so far  the screen hasn't flickered.  I shall wait for a few hours and if I have no more probs with the monitor I will close this question and accept your answer

dobbynp,
   Your may have a loose cable or you monitor may be going bad.  Check the video cable and power cable. Make sure they are firmly in the connector.

Swap your monitor out with a known good monitor.

Best wishes, war1

Hi

It looks as if your monitor or cable is faulty, the only way to be sure is to swap it for a known good monitor and test it on your PC, if all is well then eliminate the cables next.

Eliminating the monitor cable may result in lower than acceptable brightness levels.
Substituting a known good cable may help though.
