Somehow i have no audio/sound device?

that's sad...

to reinstall go to control panel , add hardware ,
click next then let it search for connected software ,
then select yes i have already connected the
hardware , then it will bring up a list .
Then scroll to the bottom and select add a
new hardware device , then select install hardware
that i manually select from a list , scroll down to
sound / video / game controller , then on the left
scroller box search for the software manufacturer
that created your sound device i.e. [ Microsoft , Lg , Cyber Acoustics ]
on the right scroller box after selecting your
manufacturer it should show the disabled hardware.
Click it and install it , then restart your computer.
