so i have the asus cross-hair v formula-z

and my on board audio just disappeared from the device manager and sound proprieties as well as front panel audio

now i already tried the following
uninstalled realtek HD audio from programs and features tool in control panel
and re installed most updated one

that did not work

so then i figured windows might have gotten corrupted

so i deleted the partition and formatted it and re installed windows 7

and used my motherboard disc audio just to see if it worked

and nope still nothing

Any ideas
or something i haven't tried
and is there a solution without having to buy a new motherboard or case
