I would make sure all software is up to date or maybe try rolling back a video driver and see. :) How's that for useless info that doesn't help. Also it may or may not be related to Norton all. Well, just a thought, it may be needing an update. It was all the result of a flaw into the 8259 chip that use to reside on the keyboard that had a 64 bit hole into upper memory and became the place that the DOS kernel resided. This was in the days of "extended" or "expanded" lim memory and the lotus software, I think. I am not sure if "Windows" still works this way or not, but the illusion of speed was that all of the various windows were preloaded into upper memory and whatever window was required to be viewed would be pulled from video memory into your screen area. Which, to me seems to be more of the method perhaps on how the software is pulling down into video memory the next "window". I have experienced that while the little arrow is chasing its tail or various other displays, the software step has already completed a while ago. But with that said what I have noticed or so it seems, the part that has slowed up is the screen updates. Sometimes the PC flies faster than ever and then suddenly it slows way down. For what it is worth, since dropping my Norton Core subscription and using Norton 360 I get a bit of a mix.
