Thanks @sunxishan , @nvidiadev1 @WayneWWW.
I was now checking the syslog and I believe something interesting is logged.
First of all this is what was logged before the crash:

Those error messages start 4 minutes before the crash and they are continuously repeated until the crash.
Those errors are continuosly repeated in the syslog. You see here that they have started at 8AM:

Another error that i see is the following:
Aug 14 08:45:57 jnano-desktop compiz[6986]: Error: Can't initialize nvrm channel
Also this last one is continuosly repeated in the syslog.
I hope you could give me some suggestions.
Thanks!!
