Let's just say that your post lacks the meat and potatoes. Tell you what,
1| Can you please pass on your full system's specs inclusive of your OS and audio equipment?
2| Have you made sure your BIOS is up to date?
3| Are you sure your drivers are in order? If the mic is a USB driven device then make sure it's drivers as well as the chipsets are up to date.
4| If the wire movement causes the buzzing then you may have an improperly connected mic at either end.
