Trying to use an external microphone but all I get is fuzz

Trying to use an external microphone but I get nothing

Okay, so I have a Compaq Presario CQ56 (HP) and I am a musical person, therefore wishing to record music. The built-in microphone isn't to my standards, so I have a microphone that I'm trying to use. It's an average karaoke mic plugged into an adapter I guess I could say.. It's a little piece where the mic plugs in on one end and the other end has a piece that I can plug into my computer, it looks like a headphone end. When I try and use it, there's nothing there. I know for a fact that the microphone works, and the adapter piece isn't damaged, so what could be the problem?

I've checked on google and have found no answers. Please help!

Microphones are :
AKG D60S
DIXON Dynamic Microphone DM-1178

Are you using a stereo adapter for a mono mic? Pull the adapter and check the plug. If there are two dark bands, that's a stereo adapter... You need a mono adapter for the mic. It should only have one dark band.

The mic cord has one black band, as does the adapter.
