hi, have you tried using the speaker to listen to audio and check if it is work. also try using the head phone on another computer to see if it is functioning. try also going to start then control panel, then sound and speech devices and check click the sound icon. make sure that the volume is not muted. then click the audio tab and make sure that there is a device selected.
go to start then run and type rstrui.exe then go to restore pc to an earlier time when the pc was working.
system restore can also be accessed, from start, all programs, accessories, system tools.
if it still doesn't work then you will need to download the klite sound codec pack from here
