Geforce 256 nvidias chipset and Athlon

My computer hangs when i try to play games. I think there is some kind og memory problem. Earlier i had a Riva TNT2 64 with nvidias chipset. There was a memoryproblem with it and i had to fix my register with a file from micrsoft. Does Geforce256 with nvidias chipset have the same problem?
If so, how can i fix it??
