Well, those are certainly powerful enough machines.

Do you have a very fast Internet connection? I would assume the fans go
crazy, but unless your room is very hot and the machines full of dust,
they should not crash from overheating.

Let me see...

OK first of all, at least on the version I have
(devuan-jessie-i386-alpha4-netboot.iso) there is no graphical installer.
So it's most likely nothing to do with your graphics chip.

Second of all, there is no top on the installer and the busybox version
of ps that is on the installer is completely striped down.

So you may have to resort to parsing /proc to find the misbehaving
process. That being said, I don't know if I should say that you should
write a shell script to parse that info or if you should pick through it
by hand. It might be simpler to cp top from a compatible installation
and use that to find the misbehaving process.

Once you find that, then you will know basically what is going on.
