okay my on board sound is not working help please

[allegedsin]

i have a asus cross-hair v formula z

and i have my blue ray home theater system hookup up to pc through a 3.5 jack it did work until this morning turned PC on
and the hd audio manager is gone from control panel and i looked at device manager not there only my video card audio is there which works no problem but that through HDMI which i do not want

so i also tried installing / uninstalling the oldest to latest drivers from the site as well as the disc
and still no pop up when i plug in the 3.5 mm jack or anything in control panel or device manager

so i tried everything i know well except fresh instatll of windows but do not really want to do that i just re dowloaded and installed all 132 of my games and i would have to re update and re download them that will take another week to do just to long

anyway any suggestions

and would buying a sound card fix this?

No necessary to change one before you ensure that the old sound car and sound driver are excellent without damage.

pretty vague answer thanks for the input tho

and no need for anymore answers i am just going to buy

a new Motherboard Since i just ordered the i7-4770k since it was on sale

so with new board = no sound problems
old board on the other hand i fix it at some other time when needed
