Question

Answer 1

If the mics worked at your friends house, then they are probably not the problem.  I assume you are plugging them into the sound card on your computer, or maybe an amplifier.  I would suspect either a dirty or corroded connection or a problem in the preamp of the device.  If its an amplifier, make sure you are not applying phantom power to a dynamic microphone.  If you are using your pc sound card, you should be connecting to the red (microphone) input jack.  Without more specifics, thats all I can say.
