You should check the kernel logs. (/var/log/dmesg.*)

Powering off is unusual. Now, kernel halting due to some hardware issue,
that's a lot more common.

I've seen low-level errors power off machines before. If you have logs
available in your CMOS/BIOS settings that may shine some light on it.

Well, I'm a total outsider here, so I can't speak to exactly what they
are doing. But, they do these experiments where they put you in an
MRI machine (or something) and then ask you to do stuff (listen to
music, answer some questions, etc) and watch what happens in your
brain when you're thinking about it. In addition to the $50 or
whatever, they also give you a picture of your brain. :)

Yeah, I really don't think it's the images themselves... But I don't
know that.
