Uninstalling Audio Drivers

[Freddy]

I was wondering how I uninstall audio drivers, I went
to 'system' in my control pannle but it didn't give me
the option to uninstall them when I right click.

I recently bought a new motherboard and my uncle was
helping me out with it over the net, and I installed the
wrong audio drivers and now when i boot up with audio
enabled it goes really slow and then freezes after a
while. Do I need to have audio enabled on startup to
uninstall them?
