Randomly chosen screensavers were infamous for that sort of thing, with
one or more of them crashing a system.  Picking just one to run can test
whether that's a cause.

That shouldn't be a cause for a crash.  Wake on LAN is a way to make a
powered off PC start booting by sending a trigger sequence to it over
the LAN.  It shouldn't affect anything on a running system.  It's a
function of the LAN card, itself.

It is possible, that a device configured in a certain way may not shut
down as desired when you shut down a PC.  It's also possible that WOL
status is reset as shut down, so a WOL signal never actually wakes up
the NIC.
