Guys, help.

In General, a year ago I bought a Blue Yeti microphone were working fine, but a month ago I had a problem with the hard drive, so the computer never used a microphone and stood in one place, I didn't touch it. In the end, when the hard drive began to work properly, I decided to talk to a friend on Skype, and to my surprise the microphone did not work. I at first sinned on fire wood or Windows, but now do not understand anything. When the knock on the buttons on the microphone, it is great to hear that knock, but the voice and stuff doesn't catch. Also, another problem, the microphone works fine even after I turned it off in control panel sound. Those, there is a tab to the dynamics of the recording if I turn off the microphone in the tab record, it still works, maybe in the tab speakers it is also possible to configure, add to it a volume or even mute. What to do? How to be? The microphone is expensive, never dropped, stood like a fossil. Drag hobbits into the realm of repair or is it on the side Windows problem?
