I had a similar problem with a machine. It would reboot and go through several
reboots before it would give me a login screen. Then it would crash without
warning. It was a bad memory module; the machine would boot fine with one, but
not with two modules.
If you have more than one memory module test by using one at a time. Maybe
memtest will give some info.
