The utility disc that comes with your PC will have it on there. It's the driver disc for everything attached to your motherboard.
or
you need to find out what kind of sound card you have first.
1. 'Go to control panel'
2. then got to 'administrative tools'
3. then go to 'computer management'
4. then go to 'system tools'
5. then go to 'device manager'
6. this will show all the devices on your computer .... your sound card will be highlighted with a yellow mark. double click this and it will open up. double click again and a window will pop up with the name of the card
7. write the name down and type it in with the word "driver" in google and a site should pop up with your driver program
8. download driver and double click it to install
*if you can't find the name of the sound card and it's built-in the motherboard, you will need the name of the motherboard. That is printed on the actual motherboard
