Choppy voice when recording

I just purchased a Gateway laptop with a built in microphone. I want to use audacity with a external mic(headset) to make songs. Whenever I record my voice it is very choppy and sounds terrible. Could it be my computer settings, audacity settings, sound/audio card, or that I am using a external mic with the built in mic still working? I have used audacity before with my previous laptop and it worked fine. I would appreciate any feedback! Thanks!

The elves hate it when you double post. You might want to kill this message and leave the one under “Windows.” If anybody knows the answer, that’s the one they’re going to post to.
