dz77ga-70k installed and USB 3.0 ports do not work. Also the Realteck audio is not working properly. Any ideas? Thanks-

I have checked bios settings and updated drivers.

desinstala los controladores y vuelve a instalarlos.

prueba también descargando las actualizaciones del windows.

en dado caso que funcionen restaura tu pc aun estado donde si funcionaba o formatea el equipo y vuelve a instalar todo.

KnottWright,

VILCHIS posted the following "uninstall all drivers and reinstall the drivers again. Try running windows updates. In case it does not work, try restoring your system to a previous point or try reinstalling the Operating System and install everything again"

These are excellent steps; I would just like to add to try updating the BIOS to latest version and checking for Firmware for the USB 3.0 Updates.
