It is unusual for a software issue to cause such a symptom.  Does it
not even respond to Ctrl+Alt+F1 (Ctrl+Alt+F7 to return)?  When you
boot back up is there anything in /var/log/syslog when it crashed?
Are you sure it is not a hardware related problem, possibly
overheating, or a RAM problem?  Did it ever crash like that on 12.04?
Try running the RAM test overnight to give you some confidence.
