swehSo, as I said, my Windows PC died after a power outage, despite being on a UPS.
Today I had a little free time so I removed all the PCI cards, IDE cables, internal USB cables etc etc etc. Still no difference; the CPU fan spins. Bleh.
My voltmeter has too large pins to fit into the power connector to the motherboard, but measuring the voltage on the hard disk power connectors shows 8V on one pin and 1V on the other, relative to the black cable. (And in my idiocy I blew the protective fuse in the voltmeter when I switched it to mA DC... duh). The fact there is some voltage makes me think the machine is trying really really to power up!
I guess the Power Supply is bad :-( The stress of powerdown/up must have just killed it; normally the machine is powered 24/7. It's _possible_ the strain of switching from mains to UPS hurt it, but it was still running happily from battery. Oh well.
Unfortunately the machine machines in my graveyard are a P3-500 and a Ppro-200 and so the PSUs don't have the extra connector that modern motherboards need, so I can't try swapping them out. I guess I'll just have to invest in a new PSU and pray!
