You seem to suggest that you have two microphones. Do people hear the buzzing with both or just one of them? If one has the problem and the other doesn't, don't use the one that buzzes, or swap the buzzing one for another one to see if the problem is with your computer or your mic.
Also, make sure you have the mics plugged in securely. Buzzing can definitely come from a loosely plugged mic.
