Audio Weapon System

tried that one too, still not working

2 days ago when i started up my pc my sound driver was gone, so i just tryed to reinstall it. Unforunately, that didn't work. I have been trying all the sound drivers i can find that work for my model and still nothing. I'm using a Km2m Comb-L mobo with realtek audio ac'97 codec650 onboard chip. went to the deceive manager and it doesn't even show that the realtek driver has been installed, even after i just installed it. I'm completely lost, any ideas? This is what my deceive manager looks like, but i can't figure out why.
