microphone just dont want to work

Try disabling stereo mix and see if the mic reads then. Is your logitech headset usb? If so what model number is it.

logitech is my headset and other thing that you said i did everything that you said but it still showing me that my microphone is not plugged in

And i usb the thing what it should be in >>> device manager >> disc drives >> there should be an usb device or something like that i think

It should show under device manager.sound, video, and game controllers

Try another usb port for the headset

Scroll down and show me the rest of your device manager with a screenshot

If the headset doesn't work in another usb port, it may be bad. Also check for a mute button on the logitech headset. It should be the inline version

Try the new version just released

Firefox

Apologies, that was a suggestion for another thread with a memory issue.
