Hi to all . I managed yo install 10.8.2 on Gigabyte GA-EP35C DS3R First start was ok with network but no sound (i did check Realtek ALC889A codec at the installation process) All apps worked ok and i tried to manually update to 10.8.5 . The updates showed ok and after i got a message that the update failed . On next restart update dosent work (appstore fails to start) and i have no network (cable is disconnected) Although the network card is flashing. Also when the monitor shuts off (screensaver) it dosent come back again. Does anyone have a sollution to this?
