What sound is it your looking for?? Are you getting video on the screen?
If the board has been on the shelf for a while it may need a bios update.
At this point, any sound. Without the memory I get three beeps. With any of the 4 memory modules installed, I get nothing. The board I just got from Newegg, and to get the system to at least POST I can't imagine I need a BIOS update yet.
