I had once. I press the computer button and immediately a terrible whisper, knock and crush and crack. I am accustomed to computer breakdowns, but my legs were pulled up so that my legs would not break away from the disc that had broken. I just perceived so. That it was Winchester that started and flew away. Or the SD. It turned out that exactly at the moment when I pressed the switch button, someone behind the wall started drilling something, it seemed. A few seconds came to himself.
