I will try that. This is a different behaviour however as it is not single VMs 
that freezes, it literally is everything. Leaving Xorg and going to a console 
doesn't work, nothing I do has any effect. I am not sure if magic sysrq is 
enabled on qubes, I guess I would have to test it while it is still working, 
but if it is, it also didn't work.

It is not a temperature problem, they are far below the standard temperatures 
even. I will run a memory test and report back if that can be the problem.
