"crash" is a multipurpose term & has a range of meanings. I take it in
this case that the system declines to respond to you, that there's
nothing on the screen.
Since the times you point out (when you're using it, maybe 4:00 am) are
times when it's busy, hardware is one suspicion.
It's also possible you don't have enough RAM & they system's simply
thrashing. How much did you say? What's the disk light doing?
You might edit /etc/sysconfig/syslog so as to make syslogd write "marks"
to the system log every so often: this will give some idea of when thigs
go awry.
If you have another system handy, you could also configure syslogd on
the laptop to log to the other system (doesn't preclude existing logs,
doesn't do bad things if the other system's not listening, but do
specify IP address and not hostname). Make sure the other system is
configured to listen, it's not by default.
Does a quick press of the power switch cause it to shut down properly?
Note, if it's thrashing this might take an hour or more. Be patient.
Note, if the disk light is not hard on, then the system's not thrashing.
