Intel z77ga-70k Motherboard with i7-3770k cpu

I have recently installed Mountain Lion on the intel z77ga-70k motherboard with i7-3770k cpu.

everything work well except the following:
Audio - can't find audio even though system information detects the device.
Wifi - can't find airport (wifi)
when I play a youtube video, it pauses after a few seconds (no sound)

I followed the post
"Hit a wall, (Can't restart System)"
but there was no solution for the above.
Can anyone help.
