Why does the system completely freeze when working in Linux?

Question

linux

I apologize in advance: the topic has been discussed more than once, but I have not been able to identify the problem.
We have
a description: Notebook
product: Portege Z930 (PT234R)
Description: elementary OS Luna
Release: 0.2
Codename: luna
During operation, the system freezes completely: there is no way to restart X, the CAPSLOCK indicator does not light up.
/var/log/syslog doesn't get anything good at the moment of freezing:

I sin on iron, but there is still no memory or hard at hand to check.

Have you tried installing a working Linux? bubuntu for example? or mint?
