Question : Problem: no sound!

Ok,good luck on this one. Got a Dell 8400 that came with a sound blaster live  24-bit sound card,Iv'e been working with Dell  but no solution.  They replaced the motherboard twice and soundcard,what is happing is that my commuter does not see the sound card. I have a internal sound device that works,but want my soundcard back. disabled internal sound,but everytime i try to install software for soundcard the computer says there is no hardwareto be found. ANY IDEAS?
