GeForce 7950 GTOC - Animation Paging Out of Order

I've got a GeForce 7950 GTOC, and in some games, there's an animation
problem. For example, in Square Enix's PlayOnline application to launch
Final Fantasy XI, after Windows XP Home has been running for a while, the
animation of the PlayOnline viewer is messed up. The paging is all out of
order. Rebooting the computer fixes it, but the longer WinXP is running,
the more screwed up the animation gets. Imagine a couple of seconds of
animation in which the pages play in a random order. That's what it looks
like, jittery and jumping all over the place. Final Fantasy XI, itself,
however, animates normally as do most other games.

Updating the driver has never helped.

What do you think the problem could be?
