OpenSUSE crashes/freezes when I turn off my monitor

[morfanaion]

Last friday I went home from work and just turned off my monitor, as a program I had written needed to run a durability test over the weekend. Unfortunately it seems that the moment I turned off my monitor, Linux just froze, quite evidently as it said this morning that the time was still Friday 17:13. From the syslog I got the following on that time:

Anyone has any idea what this means and what I can do? It's not the first time it crashes as soon as I turn my monitor off and it's really starting to bug me. I never had this particular problem before.

a little followup, yesterday I went home from work again, this time leaving my monitor on. Alas, I found my monitor on stand-by and again linux has crashed/frozen on me, this time the syslogs show the following:

What version of Suse?

Check you fans and temperatures. This could be a hardware problem.
