You mentioned that your old as dirt 98SE does not have any problems. I have a 
question about it. Have you done any of the updates to it? With all the MS security 
updates there may have been a dll that chaged or something? 

You are fighting maybe that or the differences in display chips and their associated 
drivers.
 
just was wondering?
