Sound + Wifi problems

K I have an X-fi extreme music + a D-link PCI wifi card. I changed the mobo from an Epox to the DFI Expert.
Basically there's no sound, although the X-fi is recognised and there's no error message, just no output watsoever. I thought i would just uninstall and reinstall it, but nothing change :|
For the wifi card, although it's connected, there's no data coming in, and im pretty damn sure all the settings is correct.

I thought of reinstalling windows but that's too much hassle, is there a way to fix this ?
