sblive 5.1 and xp driver

I was wondering if anyone has encountered this problem with a SBlive
5.1 drivers and winXP before.

Basically when using the default native drivers supplied with winXP
for the sblive my system is rock solid (810lmr v7.1 m/b & MSI
GF4mx440), after installing the latest sblive drivers from creative
for XP (the uni drv pack) my system keeps rebooting at random times
causing winXP to tell me it has recovered from a serious error
everytime. Remove creative drivers and use native XP drivers back to
rock solid system. I would like the added functions (EAX etc) from the
creative drivers .
