None of the speakers in the shystem work.

Hello there!

Well, here we got a few things to check
1) Type os sound card you got, 5.1 , 6.1 7.1??
2) Depending on your system windows Xp or Vista? adjust in control panel , the speaker mode, for above configutarions. example: for 5.1 surroung sound .
3) verify if you on bios disable the on board sound, back conections , and the mixer is enable, and nothing on mute. **
that's it!
