I've been having problem with my Gainward Geforce 4 Ti4200 video card.
I have tried the following video drivers and have had problems with both.

With V42.30(Final) I experienced terrible slow down out of nowhere in Kazham, or when the party is casting spells.
With 53.03 I experienced something a little worse, complete and total lock up of my computer. The graphics would distort and the program would crash.
Dec. 20th, A friend and I build a new computer, and I carried my video card over from my old one. I've never had these problems with my old computer, and unfortunately I'm not positive of what version drivers I was using. In fact, I wasn't haven't problems with my new computer until the 10th of Jan. It was a infrequent problem at first, but now it seems to happen after 10 minutes or so of play.
Someone suggested turning off hyperthreading but I have no idea how to do that, and not sure if that would even do anything.
Here's what I got.
