Just as an experiment, I would try going in the BIOS and disabling the sound all together, and see what effect that has on the problem... Being an ASUS, you should also have a physical jumper somewhere to disable the sound also, in case the BIOS switch doesn't do anything... I seem to remember SB Live cards messing with several games, though that's just a vague impression. If that solves the problem, then just leave it off and put in an actual sound card. I have successfully run an ATI 8500/64, Catylist drivers, with a Creative Audigy sound card on an ASUS P4T533C, and had no problems with SFC3
