When you have a problem you are probably offline and cannot access anything on the web which means you will pickup the phone. But, if you rely on VoIP then that will also not be an option, so you make a cellphone call at considerable expense to you and us when we call you back. That's why we recommend you take the time now to search, decide, download software that will keep your computer clean and provide problem management tools. If your computer should fail to start or run in the future and you have not pre-organised a support person for that then do so now, before the event.
