Crash? Mouse still moves

Question

So my MacBook Pro crashes, mouse still moves but it doesn't respond to other inputs. This occurs on the version installed on my SSD when i startup with the OS on my regular HDD it doesn't seem to have the problem.
Below my console log, but it doesn't seem to have anything to do with the crashes. Anyone an idea how to fix this without reinstalling the complete system and having to install all software again?

Answer 1

I've reinstalled the optical drive and kept the SDD in, on the original HDD position. Same problem occurs, after about an hour, some programs start to freeze, then i get the beach ball and after a couple of seconds it vanishes and the system freezes completely.
