There's one more step: reset the CMOS. There should be a jumper covering
two of three pins near the CMOS battery, hopefully labelled "Reset".
Move the jumper to the other side of the three pins, then power up the
computer. That should clear the CMOS back to default settings. If it
boots then remember to move the jumper back to the original setting
(otherwise the CMOS will be cleared at every boot)

The motherboard on the failing system is a non-UEFI Asus P6T. The CPU
is an Intel i7 950. I have 32GB of Crucial DDR3 RAM in it. The whole
thing dates from 2009/2010 or so. I'm pretty sure I replaced the
motherboard at least once already. There are four or five spinning
disks of various sizes and ages.
A few minor updates.
First, the problem remains the same: I never get through the POST, much
less to the BIOS. No beep codes (or beeps at all), no display, no
nothing; it just remains silent as the fans spin.
Second, there seems to be power to the computer. The internal MB power
indicator lights up, the fans spin up, the hard drives seem to all spin
up, and the graphics card at least lights up.
Third, I tried putting in a fresh CMOS battery. Still nothing.
Fourth, I tried swapping the memory around in various configurations.
Still nothing.
Next up I will see if I can find a graphics card to swap out the current
one for testing. If that makes no difference, then there are only major
components left as suspects -- the motherboard itself and the power
supply (though that seems to be working: see above). I don't have an
extra power supply, but this one seems to pass the smell test. That
leaves the motherboard. I don't really know how to test a bare
motherboard. Is there anything else I should be trying before I give up?
(Where "giving up" means looking for another computer I can migrate
all/most/some of the existing hardware to -- maybe an old tower that has
room for lots of spinning drives.)
Thanks for any advice!
