Sounds like you have an IRQ conflict, and the sound card is getting beat out for the resource.
Are you maxed out on peripherals that are eating up all your IRQs, possibly due to a recent hardware addition? This was exactly the same problem presentd to me by a customer not long ago. Her problem was resolved by upgrading to a USB mouse, freeing up an IRQ for the resource to use. Of course, you'd have to have USB support for that, and I can't assume that you do.
You can check the IRQs using a utility like Windows System Information (Start, Accesories, System Tools, System Information) and looking under hardware resources/IRQs.
I'm assuming that only the SB16 driver is conflicting... You can try to disable some other devices that you use infrequently, or possibly an empty one can be freed up (Often this is done with the secondary IDE channel, if not used.).
If you absolutely have to have everything you're running, You can also resolve this by going out and picking up a used genuine SB card. Genuine Creatinv products only need one driver, since they do not have to concern themselves with compatibility. Even if your sound is on-board, you can disable it and use the SB card. (NOTE: Make sure you can software disable the sound card BEFORE you go out and buy another card, I don't wanna waste your money).
Good luck,
Tim
