You can go digging for information in /var/log - I would especially
take a look at /var/log/boot.log, kern.log and dmesg.

That's not good, it could indicate a driver/firmware/hardware problem.
Have you run memtest86? Maybe it would be a good idea to do a few runs
if you can spare the time. It could also be a kernel bug, that an
upgrade would fix, it is impossible to know without more information.
Start with the logs.
