The usual procedure on troubleshooting video issues is to swap out the
monitor and the vidoecard to verify if either of them is the problem. You
did one - now try the other.

I have shadows going across my screen. For example, if i
open up a picture either side of it a shadow line goes
across the screen. I have run an anti virus check and also
ran Ad Aware. But it is still there. I thought it may have
been my monitor about to die on me so went and bought a
new one. But the shadows are stil there. Any suggestions?
