Answers.Body: <p>Yes there can be a common cause. The change in hardware does not necessarily mean that there is no bug in the software (even between different versions), that causes this to happen and that is triggered by some (non-standard) sequence in one of your ebooks. </p>
  
  <p>If you have PDF files, it might even be a bug in the program that is part of the PDF file (it can be causing some infinite loop, or memory/stack overflow).</p>
  
  <p>Sometimes this freezing behaviour is triggered on ebook readers while the (new) files are scanned. This is one of the reasons why I recommend storing the ebooks on an removable medium, which allows you to search for and remove the offending file even if the device doesn't start anymore. </p>
  
  <p>I don't know how many ebooks you are talking but you should consider opening them with some software that actually complains about non-standard/faulty files (e.g. using <code>evince</code> started from the command line in bash scripts, running <code>epub-check</code> on EPUB files)</p>

  (Asked by: username_0 on 2014-03-06)
  
  I used to have a Kindle 3 (keyboard). After almost 3 years of honourable service, it started getting stuck more and more, until reset wasn't solving anything anymore.
  
  The very helpful Amazon customer service replaced it (albeit out-of-warranty) with a Kindle Touch. Happy again, I copied some books I was reading to the new device and started reading.
  
  After less than a month, the Touch got stuck too. Now since I don't believe in cursed ebook users, I'm trying to figure out if there is a common cause. I haven't treated any reader badly, always charged before getting the warning, never let it fall (at least the new one).
  
  I'm starting to suspect it's because of some book I loaded, can it be? I usually use Calibre on Windows 7 to manage ebooks.
