It froze after about half an hour, in exactly the same way as before.
If you have something you would like me to run to give you more
information please let me know.  Thanks!

Title:
  regular system freeze - 16.04

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Seems this is common enough to have a few requests on Ask Ubuntu:
  http://askubuntu.com/search?q=16.04+freeze

  I would update my kernel, as suggested, however there are not clear
  instructions and I have had issues doing kernel upgrades in the past.
  The freezes are not Chrome only, as they also occur when Chrome is not
  running, though, from memory, Steam uses some of the same things as
  Chrome.  Once the freeze happens a hard reset (holding down the power
  button) and restarting is the only solution (I can't even open a CLI
  instance).

  Thanks for your time, hope there is a fix soon.  Best regards,

  Taz
