Audio stopped working (all audio) + windowsupdate doesn't work.

Hello,
Im starting te get desperate, i really tried everything to solve this.
My audio stopped working since windows update dusn't work anymore,
i tried to add bits to the windows services. doesn't work.
if i click update @windows update screen. it just freezes.
im not sure about the link between my audio problem & my windows update.
i can't manually download an audio driver, because my soundcar is attached to my motherboard.

Thanks in advance.
