I have the same gfx card as you do and had the same problem... at one time. Grab the newest gfx driver from nvidia (they just released a new one a few days ago), I'll give you a link: http://www.nvidia.com/object/winxp_2k_77.77.html
Glide64 v.0.8 is the fix for this problem you are getting though... in Paper Mario I mean...

I'm not having the problem i'm just testing other graphics plugins to see which one solves the first poster's problem. Glide 64 flickers and freezes on my system though. I already have the newest driver.
EDIT: I think the problem is that you have some cheats on.
