that's not at all unusual.  many crashes don't result in any useful info
in the logs because either a) the machine locked up and wasn't able to
log anything or b) the log file(s) weren't flushed to disk.

unless your machine is on a good UPS, the most likely culprit is
power.  i.e. temporary power loss or low voltage fluctuation.

a UPS is good for more than just backup power and shutting down cleanly,
it's great for regulating the power supply to your computer so you get
steady clean power without any spikes or dips.
