The most obvious one would be "bad hardware".

When you say it "freezes" is the machine still ping'able from another
machine in your network?
You could start a script like "vmstat 1 >> /tmp/vmstat.log" or similar
which runs all the time to get one of the latest log entries.
/var/log/messages is really empty when your box freezes?
Is X running while this is happening?
