Solved... I think.
Bought a new graphics card and when I went to install it the PSU did not
turn back on. It must have been on it's last legs.
Bought a new 500W PSU, installed and... Debian shutdown normally. No
oddities.
Case closed.
Note: if you get similar oddities it might help to run "dmesg" or
"journalctl --since=yesterday" in a terminal and observe anything in bold
for clues.
