Download this free program, it will scan your computer and tell you which motherboard you have. After the scan at the bottom it will usually have a link to the motherboards website. It's best to download the correct drivers for your motherboard built-in soundcard xp or vista. Also make sure your built-in soundcard is enabled in the bios.
