Make sure that the drivers for the MB's chipset and the onboard sound adapter(if applicable) were reinstalled, the onboard sound adapter is enabled in BIOS, and there's no problem with the sound adapter in Device Manager.

If those are ok, then the sound adapter may be bad. Install a PCI sound card. If it works ok, then the onboard sound adapter has died.

Also, if you have future problems with the ethernet port, then the onboard ehternet controller may be bad. install a PCI network card to replace it.
