My self-built Win XP Pro MCE machine will not boot. The BioStar splash
screen comes on, but then the machine shuts down before the P.O.S.T. info
displays.

BioStar mobo, P-4 3.0 GB dual core, 2 GB RAM, 80 GB Hitachi IDE HDD, one LG
DVD IDE combo drive. Multi-slot card reader (no cards inserted), no floppy
drive.

I've unplugged all peripherals, including the LAN cable. The machine is part
of a 6 box LAN. All was fine at last shutdown after an update of MS
Defender.

Need more info.
Do you get any bios beeps?
Does your keyboard's LEDs flash? Are you using a wireless keyboard? Check
the battery.
Does the Motherboard's LED light up?
Do the fans spin?

Anything will help.

Shooting in the dark:
As JAD says: check CMOS battery, reset CMOS
Check HDD conectors, make sure they arer seated properly
Sometimes you can reseat RAM - it gets "crusty"
Check the power supply with a multimeter. Are all the voltages good?
Do you have any bulging capacitors on the motherboard?

Where you playing with any USB devices before this behavior happened?
Do you/did you smell an acrid oder? (Burnt plastic).

I found the problem. The CPU cooler socket broke. May have burned out the
CPU. See the pic:

The metal retainer didn't touch any conductors, but the CPU may have
overheated.

Not necessarily, I've had this happen before. I would get hold of a new
plastic retaining assembly, if thats what broke, and fir it to the
motherboard (try ebay or similar) and refit everything - you may be
pleasantly surprised. The CPU should have cut out before it overheated.
