do you have windows xp? if so, go to your control panel, click on the icon for printers and other hardware. you should see a little box on the side where there is a link for sounds speech and audio devices. click that and then click on the sound and audio devices. it should tell you what your sound card is, then go to the maker of the sound card's website and they should have drivers for your card to download. Hopefuly this helps, i can't make it any more clear than this
