Unfortunately, these kinds of problems are hard to diagnose, because
they are usually (not always, but most of the time) caused by hardware
problems.  So you can check the usual culprits for hardware failure,
but obviously if it's working okay at the moment, it can be extremely
difficult to figure out where the blame lies.

If you can figure out whether there are any patterns to when the
system freezes, and even what it was doing at the time, you will have
the most important clues for starting with.

Good luck.
