maybe you could specify what the problem exactly is. what was the error/problem message you got?
also, could you tell us which sound card you have? (it's the name that's in the 'multimedia/audio controller' tab. in the Device manager(if you dont know how to get there, see the post above)
. (something like AC'97 audio or anything like that)
a driver reinstall might help, but if we know the name of the card, we can also help you there.
