Quite often my new computer running on windows 8; It is a Samsung ATIV Smart PC makes these chiming noises, in fact it is doing it as I type this note. When it is chiming I am prevented from typing. Does anyone know what is causing this? Its seems very frequent and is annoying. I don't know if it is Samsung issue or a Windows issue, I have never come across it before with previous computers so thought it may have something to do with Windows 8 ?? Thank you in advance.
