I have an older Presario, still (and happily) running Win-98. Recently vertical red lines can obscure photos, and sometimes illustrations, on the web and often in my offline picture files. Not all photos are obscured, and the vertical red lines don't run through text, etc. This is not a monitor issue... cause it was present on my old monitor and now on my new flat screen, and is not in the same position -- but where ever the photo appears. Anyone know what I'm missing here? THANKS
