So, while troubleshooting today I thought I smelled an ominously acrid
odor of burning plastic. I wasn't sure whether it was real or a figment
of my stressed imagination, but when I opened the case, sure enough, the
cable feeding the GPU had burned and broken.

Fortunately, I don't see damage to the system's power cable or to the
GPU itself, just to the 6 pin to 8 pin PCIE adapter cable (the HP PSU
has only 6 pin cables, and the GPU needs an 8 pin connection). I
remember debating at the time (3 years ago) whether to buy the cheapest
one I could find, or to invest a few dollars more to buy a brand name
unit from a reputable company. I rolled the dice on the former, and it
did last three years - and hopefully didn't take out anything else with
it.

I'm going to order another one, from a reputable company this time, and
hope that it was just the cheapo implementation that was flawed, and
not the whole concept of 6 pin to 8 pin adapter cables ...
