OK, this one is a tricky. My PC f****d up and so I had to reinstall Windows, and so I lost everything. And when I restarted my sound card won't work. It won't play ANYTHING. However whenever one of those annoyign Windows ad's come up it makes this beeping sound (it also does this whenever I am confirming something in another program like the save changes on Word). This is what it says when I go to device manager, a little yellow exclamation mark shows up for some reason. What do I do?
