This can happen when your sound card is set to record everything that comes out of your computer speakers.
Click on the Windows "Start" button, select "All Programs" | "Accessories" | "Entertainment" | "Volume Control". This will bring up the windows volume control. Next, in the "Play Control" select "Options" then "Properties". Place a dot in where it says "Recording" (under "Playback"), and click "OK". This will bring up the "Record Control" panel. To remove the check in "select" under "What You Hear" or "Stereo Mix" (varies depending on the manufacturer) you will need to check the appropriate input, most likely "Line In" or "Mic".
This problem can also occur when you are using an analog mixer in your setup. Carefully follow all of your signal paths to ensure that your sound cards audio output is not being looped back into itself. You should also consider the possibility of your microphone picking up the signal from your speakers or headphones.
