My micro SD card issue

I have a micros SD card. When I put it into my windows 7 machine using USB adapter, windows explorer shows that and I also can open it and see the files and folders. But I can't run the files and open the folders. When I double click on either of those, windows hangs. I even can't format it because format fails. I also tried to recover it's data using some tools but couldn't success again. I also tried scan and fix pop-up.
I don't think it's dead but surely there is a problem with it. And also there isn't any switch on the card reader or micro sd card.
Is there any idea how to fix that?
