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)
