Realtek HD Audio Manager, Buzzing noise in playback

I've got a headset with a mic and In the Audio Manager i've got the playback volume muted. When i un-mute it there is a faint buzzing noise. thats not a big problem but when i want to talk to friends on skype. I'm really quiet and they can hear the buzzing noise. When I try to use the Microphone Boost, the buzzing gets louder. Its a Deep Buzzing noise. I've done many things to try and fix this, messing around with it, going online to find a fix.

I know its not my headset or my mic causeing it; did a test with another headset.

If this problem has been solved already, please link - Thanks

i don't even use/have speakers. i only have my headset with a mic. I unpluged the mic jack and only have the headset jack in and can't hear any buzzing. only when i have my mic active and the playback volume on, there's buzzing.

AC powered device? the only other thing i have is my Hawking Wireless Adapter for connecting to the internet.

having the same problem but the buzzing got louder.

Did some digging and found that my motherboard is a: Ultra Durable 3 Motherboard that has an onboard Accrleration, with Intel core i7 950.

mine looks the same as yours without the two extras.

i'm pretty sure that the right driver is installed, my dad helped me build and install all that i needed.

i was trying to see if i could disconnect the front panel, but i didn't because my dad wasn't around and i don't know what cable is what. instead i want to clean up the dust in my fans. after doing that i started up my PC, for a chance i checked if there was any buzzing. i couldn't hear anything. the next thing i tryed was calling my brother on skype. sure enough he couldn't hear it, even if i turn up my mic booster. before i mark this as solved, i'm going to wait a few days just to make sure what ever i did made it stop buzzing.
