Any storms in the area?
If you're comfortable with it, strip the system down. Remove all cards
including video, remove all RAM, unplug all externals (even the mouse,kb
and monitor), unplug all connections from the mb EXCEPT the P1/P2 power
supply connectors and front power switch cable. (Also unplug all power from
all drives, including floppy).
Plug in and attempt to power up to beep codes. If you do get beep codes the
re-install the RAM and video and see if no POST returns. Continue
re-installing components until you identify the source.
IF when stripped down the machine still won't attempt POST or produce
error/beep codes, then you've got a bad power supply, motherboard, or CPU -
or some combination of the three.
The power supply can be tested with a multimeter or voltmeter OR a
simple/cheap "go/no-go" supply tester bought at a local dealer or
CompUSA/Fry's, etc. (Using same the PS can be tested w/o stripping the
system down, obviously).
If the PS checks good, then short of having an extra P4/478-pin 400FSB CPU
lying around, you'll want to take the system to a shop to find out which is
bad: the CPU or motherboard.

*PS - the power supply has standard ATX connectors, but the housing
dimensions may not match with a retail replacement.
