Windows is infamous for trashing sound drivers. The good news is that usually a driver install fixes it. Check your motherboard box and see what audio it has or list your audio card.
From your comment I think you have a Realtek, download the driver from here
http://www.realtek.com.tw/DOWNLOADS/
then right click on Computer choose Manage then on the left choose Device Manager. If there is a sound device listed or multiple ones, delete them and reboot. Cancel the Windows automatic install, return to the Device Manager, choose your sound device, update the driver by not allowing Windows to find automatically but instead manually install the driver you downloaded.
