I bought a new keyboard for my laptop. And a new DVD drive from you guys. Then I installed it using your directions. Everything went well restarted it and everything seemed ok. My wife started working on a word file while listening to music. All of a sudden the speakers started crackling then the sound failed. the Speakers themselves seem dead. we restarted several times and tried messing with the sound in preferences and nothing happening. Did a rebuild desktop and nothing.

I think my speakers have failed... Can I replace them? do you sell them?

I doubt I did anything cause it was all working went I put it back together. But who knows.

Please advise.
