These are the wires that should of came /w your card.
Just like Hex said you need to first hook the video.
You have three options which the third is optional.
1. yellow analog output
2. svideo
Optional
3. Video Component. In which you need the adaptor that goes on the 2nd analog connection to do this.
Next is the audio.
First option is connect directly from the video card to whatever you're hooking it up to.
You would use this cable for doing that.
The next method would be to plug the same output into your sound card.
In which this would be the cable you would use to get the audio out of your sound card.
If you sound card has a digital fiber optic or coax will give you a better quality output.
However, your video card also has a digital output. Which you can pass thru to a receiver/tv or even your sound card.
