I would suggest reseating the CPU module and removing any PCI cards present.
(I have an Alphaserver 800 which became a complete brick while a combination
of PCI cards were present that it didn't like.) If there are any EISA cards
present, I would leave them in place because there may be issues with the
config utility that has to be run when the EISA bus configuration is
modified. Other than that, I suggest trying the system with just the bare
essentials present and seeing what happens.
I think that I tried reseating the CPU card a while ago, and it didn't
fix the problem. I also tried removing all the PCI cards, and that also
did nothing. I'll try removing all of the RAM and PCI cards, and
reseating the CPU card again, and see if that does anything.
It would be useful to know if the fans start. Fan
problems on some alphas
cause the whole thing to shut down. Also, there is an interlock microswitch
to prevent power up when the cover is open. This is probably not the problem
here though as the symptoms are as if the front panel power switch is off.
Yes, all of the fans start. If one of the case fans is disconnected, the
system powers up for a second and then completely shuts off.

there is)?

It has an extra power supply installed, so the only way it could be a
power supply problem is if both have failed. I can disconnect either
power supply, and nothing changes.
