Hi! So my problem is that when I talk to others with microphone on Skype then the other person that I am talking to can hear the sound of my computer.

So if I'm like playing a game and shoot with any weapon then the others can hear it. I'm using headset. I've also tryed to turn of the volume in my headset still the other can hear my sounds on the computer and even when i disconnect my microphone from the computer they can still hear sounds from my computer. Please how can i fix this?

I had the same problem by the way! I totally know how you feel!
All you need to do is:
Either stop playing! (Joking!) :P
Or you can just buy a new headsets (That is what i did)
IF that didnt work well, sorry!

With all my love, Reem

Well its not the headset because even when i remove all the contacts my headset is using from the computer it's still same, the others can still hear my sounds.

So there is no problem whit my headset(s).

Check your mixer settings - you'll need to switch to the "Record" settings (Options -> Properties, select Recording, click OK), then check what devices are selected - you only want the microphone.

You should either close the sounds of other applications or you should not play other application while talking.
