I recently started my computer over with Windows XP by re-installing it. However, this delted 4 of my drivers. The drivers I need to get are: USB Controller, SM Bus Controller, Multimedia Audio Controller, and Video Controller (VGA compatible). Atleast that is what drivers my computer says I need to get under my device manager. I think this is why I also have no sound. Can anyone help me figure out where to get these drivers at?
