Audio card fail to be detected after a short power failure.

[FailUpdate]

So yesterday was pretty windy, and we lost power in a few seconds. My computer was rebooted but after coming up, it could not detect the sound card... It is a Sound Blaster Z. Is there any suggestion that you guys can give me?

Try reseating the card (remove and firmly replace). If still not detected, a power surge when power was restored may have damaged it.
Try the card in another PC if possible and if it doesn't work in that one either, it's definitely been damaged, most likely by power surge assuming your PC isn't plugged in to a surge-protection socket.
