Well, brand new power supply and the system behaves the same problematic way as before.
So next try is the memory, as another list reply suggested. I've had memtest86 running against both DIMMs for 47+ hours and counting, 70 total passes so far, and 0 errors. Remember I'd already tried removing first one DIMM, then the other, and the problem repro'd either way. So by these measures it'd seem the memory is OK? I know some mem problems take days to show up so I'll just leave this running for a couple more days anyway.
Not much more I can do here, as I've seen repros with most everything else unplugged so I'm now thinking it must be the motherboard. Perhaps I will try reseating the CPU--haven't done that yet.
It could be the motherboard or CPU, but try unplugging all USB devices and removing all the internal cards that you can, first. If it boots okay then, try adding them back, one at a time, until you find the offending device. -- Rich
