I don't have a Dell, but was intrigued by the story and checked the
capacitors.  For better or worse, they were fine.

Turns out that my PC isn't booting because one single pin bent & fell
off of the processor.  Since I had to replace that, and also didn't
think the CPU was the issue anyway, I ordered a new CPU, motherboard,
RAM and PSU.  Gotta wait 3 business days for it all to arrive, and
then to assemble it, but at least the issue should be resolved
(assuming it was a hardware problem, which it probably was).

Thanks to everyone for your help and suggestions along the way.  I'll
reply to this if the issue persists with the new hardware, but
otherwise feel free to assume the new parts fixed it.
