bluescreen caused by my audio devices

i am having a dv-4 pavilion, and i am using a creative SB 5.1 x-fi sound card
usb.
i recently had a bluescreen and the report said i have an audio software
problem.
the creative sounds great but i seems it's the root of the problem. i would
to keep it but run nicely without problem. i would to know if it is a
conflict problem, or a device software problem.
i received this report which is a little confusing for me.
i hope somebody will help me to discover something and sort out a solution
for me.
thanks.
