Try to differentiate between youre sound card drivers and the sound card GUI you might whant to remove the GUI and leave the drivers, same as with video drivers and video GUI or keyboard drives and keyboard GIU.
"If you have the installation disk (just in case)"Normally the easiest way to do this is go to add and remove programs and remove the sound card software then restart and let the pc detect the hardware and only the drivers will be installed.
And your prob will go away together with the waisted resourses.
