Good. At least you have an interim solution.

Yup, that confirms that we basically have the same setup.

Honestly, I don't remember how I got rid of the jerkiness. I do know
that I was messing around with the ALI and ATI drivers and I even blew
away my Windows 2000 intall and installed Windows XP instead.
Luckily, my hard drive died that night after I got it all setup, so I
got to set it up again on a new hard drive the very next day :) That
time I had somewhat mastered the art of getting the drivers correct, but
that is when I noticed that certain graphics operations (Opening
File->Print in any version of Adobe Acrobat Reader) would freeze the
machine hard, every single time at exactly the same point.

I think I would keep the 8500DV but get a new motherboard instead. I
had read before that the AGP support on that particular Iwill board was
spotty, but I didn't care because I had never owned an AGP card. Most
other boards out there don't have the same types of problems and I am
sure that Iwill has improved their AGP support in the past two years as
well.

Excellent.

Thanks for describing the problem. It was kinda neat to see the exact
same problem that I had happening to another user :) I mean, it sucks
that it happened to you, but it keeps me from thinking that I was just
doing something wrong with my configuration. :)
