i rather think that it could be problems like taking it from a warm
place with a lot of humidity to a cold place, where the damp condenses
and thus the weird behaviour. of course it behaves normal again after
the electric circuits are dry again.

this would also explain the "bulks" - it will keep on crashing until
the circuits are dry.
