Did you reinstall all your drivers?

i dont think so
i only reformat the computer
with the help of Broni :]
because before my audio isnt working
as far as i know many of my
drivers are outdated but i dunno
where i can download those .

What is the make and model of the computer?

The manufacturer will have the drivers on their web site.

You need to load the drivers after reinstalling an Operating System.
