So the speakers don't work or what? Whats the problem?
Have you checked to see that the sound isn't muted in windows? Click on the little speaker icon down in the right hand corner and make sure that "mute" isn't checked. Is the sound turned up on the speakers? Are the speakers plugged in? Have you tried a different set of speakers? Are you plugging the speakers into the right place on the back of the pc?
Thats about all I can think of right now......we need more info.
