Sound card and modem card not working not.

Ive just moved all my expansion cards to another motherboard with some new RAM and a new processor. Everything works fine, and I get sound out of one sound card, but not the other. Also the modem isnt recognized.
When I go onto the device manager, the cards are listed, but with a yellow question mark. Double clicking this reveals that the computer doesnt recognize the cards. I think its a code 28. What do I need to do?
