  1. Sounds like your power supply is dying. Best thing to do would be to replace it before it blows and possibly damages your other components.
  2. are you sure its gonna "blow "
  3. No. But with those symptoms, I'd change it. Any sounds other than the "whoosh" of the PSU fan is not a good sign.
