Mic Problem

I got a mic for my cpu and it worked fine for a few weeks. Then out of the blue when I would turn on my cpu, or mic for that matter, it makes this deep hummy noise, as if there's interference with it....what should a brother do?

 

Maybe the mic is too close to the speakers. Check your volume controls, and make sure the volumes aren't set too high. Also, what kind of microphone is it?

 

My first thought was a loose ground, but other than checking all the plugs I couldn't tell you how to check for a loose ground.
I guess it's possible the power supply ground could have gotten loose, but I dought it. It could be RF noise from any thing like a loose plug to a worn out brush on a fan. (then the solder would be hitting the contacts. Lots of spark, lots of RF.)

 

my speaker plug-ins were touching the mic plug-ins because they are all bunched together by the back.....it works fine now.
