Gfx Card or Monitor? (vertical blue lines)
Here is my problem:



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.
