Annoying noise when playing games

[Tastymond]

Hello I really need some help here i dont know what to do, I get a horrible noise when playing games in my headset, its like a constant buzz I think it could be coil whine, but it only happens when my microphone jack is plugged into the back of the pc, if i take it out the noise is gone, same goes for the front mic jack. Please note i have tried like 3 different headsets with microphones and the problem is still there.

Can anybody help with this problem? I made a detailed video about it and even got a replacement from overclockers and the problems still here.

i had that with an old laptop, it seemed it was bad earthing in the laptop itself, when i touched the jack plug it stopped also had it with my Razor tiamet headphones which have a seperate usb plug for power, so I plugged that into a socket adapotor and it cured the noises
