A storm blew through unexpectedly. It knocked out our DSL modem, our speakers and the DVD player to our TV. I have replaced the modem and it works just fine. Am I going to be able to JUST replace the speakers or am I going to have to replace the card? It doesn't show my speakers as existing on the system. I have unplugged, and relugged and restarted. I have tried to run a trouble shooter. The computer doesn't even "appear" to play a sound. Somebody help me PLEASE!!
