No sound

[Session]

I have just re-installed Windows on my computer (To get rid of all the spyware and free space and stuff). I also re-installed all the video and internet drivers. But my sound doesnt work. I didnt install the drivers for sound, though, because my computer was built by my dad's freind last year for Christmas and he has all the driver cds. So if someone could help me find the drivers online i would reall appreciate it.

Some Stuff you need to now:

- Sound Card is on-board. Mother Board is nForce-CK8S.
- Under my Sound, Video, And Game Controllers tab in the device manager is:
Audio Codecs
Legacy Audio Drivers
Legacy Video Capture Devices
Media Control Devices
Video Codecs
-Under Other Devices (The ones with Questsion Marks) is:
Multimedia Audio Controller

the sound drivers should be in the Nvidia nForce drivers.
