What do you mean "shutting down"?  Does it simply freeze as though
something is going into a tight loop, or does power get shut off?

Have you probed anything with a 'scope?  If the power supply is
turning off, it must be being commanded to do so, and it would be
interesting to investigate the source of the command.

I once added memory (256 KB to a Microdata 3200 -- big stuff in the
'70s) which turned the computer into a veritable noise detector --
extremely sensitive to static discharge.  Turned out to be a design
flaw in the CDC memory.  I fixed it by rebuilding the refresh circuit.

 To "reverse engineer" something is to come to comprehend it, so what a
EULA really does is to forbid comprehension.  For this they charge money?!
