Question

My microphone just stopped working, what can i do?Ok hi. i play alot of counter strike and stuff so use ventrilo alot. Last night my mic was working fine. this morning i turned my computer on and while it was loading up i unplugged my headset ( mic on the headset) and mic so untwist the wire. I plugeed it back in and loaded up vent and now my mic doesnt work. When i press test and try testing my microphone, i use press the key to enable speech and i talk. the only sound that comes back is the "beep" of when you press your "push-to-talk" button and some quiet fuzzes. I tested another mic on my computer as well and i get the same thing. I think i had this once before ages ago but cant remember how i fixed. Help would be greatly appreciated. thanks
