I wasn't watching this thread, so pardon me if this is irrelevant...
but a coworker was building a new system, and thought the PSU
was bad. The fan would jump a little but not power on all the way, nor
did anything else (LED's, hard drive, etc.) Turned out it was just
that the PII wasn't seated in its socket all the way. So it seems ATX
boards will not power up without a processor. The motherboard is in control
of the powerup sequence.
