It may be a hardware problem, such as overheating CPU, bad RAM etc. Some
motherboards such as the Intel 7501 chipset have hardware event logging on the
motherboard which allows you to go back and see if there are any hardware
problems at crash time. I found that one of my CPU's was overheating and
locking up my system through this method.
There are also some programs that will test your memory, tax your CPU at 99%
load etc, in order to try and see if it is a hardware issue. These problems
with random lockups without any warning messages in the linux /var/log files
can be very hard to narrow down. Let me know if you need the names of these. I
don't have them at hand at the moment.
