    Here is my problem:

    [​IMG]

    Happened shortly after installing some windows updates although I have no idea if it is related.

    Basically the screen has a number of vertical blue lines, when you move the mouse around you can see the individual dots changing.

    However it comes on randomly and dissapears when I install / uninstall anything. It does come back though randomly a bit later.

    It dissapears when you reboot but can come back within 10mins to several hours.

    Have updated gfx card drivers etc no luck.

    Is this a problem with the monitor (tried changing phase and clock) or the graphics card?

    Thanks for your time!

    System:

    Windows xp pro sp2
    Radeon 9500 Pro (Yes the card is old but it has served me very well and I have no need for high end video card)
    Hanns G 19" LCD (~ 1 year old)

    Definitely the graphics card if it shows up in a screenshot. If it's a separate card, try removing it and reseating it. If reseating it doesn't work, and you have tried a different driver (that is, actually updated it instead of reinstalling the same version), then it probably just needs to be replaced. That screenshot looks like a textbook failure.

    Thank you very much just wanted confirmation it was the gfx card before I replaced either. Glad it wasn't the lcd :) Will try the tests then look about replacements.
