to help I will need to know a few things

1) do you have a seperate sound card or is the sound system built into the motherboard ?

2) if they are built into the motherboard do you have all the disks that came with the computer ?

if not I will need to know the make and model of the computer (or motherboard) to direct you to the correct drivers

3) if this is a seperate sound card do you have all the disk that came with it ?

and again if not I will need to know what sound card you have to direct you to the correct drivers
