Er, why plug-talk?
Maybe (to test) a different video card (maybe a PCI). For my father's
computer, we ended up going through about a power supply, and 3
motherboards before we figured out that we needed to upgrade the BIOS.
With its on-board video, it worked. When we plugged in a AGP video
card, it wouldn't boot... no video, CPU fan spins, no other signs of
life. Sounds *exactly* like what you are describing.
Eventually, Intel released a BIOS that worked, but the associated
notes gave no clue.
The other problem I had was a bad CPU ... but I got another
unpopulated motherboard out of the deal (sigh).
