[WinXp] System error con driver nVidia

Gente:
Tengo el Win XP x64 y se me ocurrió actualizar el driver de la placa de video (nVidia geForce4 MX4000), y ahora todo el tiempo tira errores.

El error es el siguiente:

Alguna pista de que puede ser?
Ya probé de bajarme drivers mas nuevos, certificados y sin certificar, betas, etc, pero siempre tira el mismo error.
Incluso acualicé el DirectX del Windows.

Gracias..
