How to fix robotic beeping noise in turtle beach x12's when recording with fraps?

I record minecraft videos with fraps and use my turtle beach x12's for a microphone. They always worked well, but now when I play the video, everytime there's a sound, there's also a robotic beeping noise? I use stereo on fraps as it has always worked well. I do NOT have the box for the turtle beach x12s and I just want to know how to fix them without cost.
