new P4R800 will not boot-up

[Jason]

I recently decided to beefed up my CPU and motherboard, so I
purchased:
- an Intel P4 2.6c w/ hyperthreading
- an ASUS P4R800
- Transcend(TS256MRTD400) 256MB PC3200 DDR400 (times 2, 512MB total)

The motherboard has on board everything (video, sound, LAN). I put
the CPU in, the memory in both blue sockets A1 and B1 (as instructed
in the manual), plugged in the 300watt ATX power supply, ATX switch,
and PC speaker.

When I plug in the power supply the power LED comes on, on the
motherboard. When I push the ATX switch the CPU cooling fan comes on,
and the power supply fan comes on, and that's it. No video, no beeps,
no drives turning (when I plug them into the board). Then if I hold
the switch nothing happens (fans don't shut down).

I contacted ASUS tech support and they suggested I isolated the board
from the case to prevent "EMI (Electromagnetic Interference)" --
nothing. I ask them again and got a detailed definition of EMI, but
no suggestions. I've exchanged the motherboard for a new one, put my
old components (ASUS P2B with Intel p2 400Mhz) back in and the
computer booted up, no problem.

Any suggestion would be greatly appriciated. I don't know if the CPU
is bad, one of the memory modules. I've tried everything I can think
of. Please help.
Thanks.

Do you have the correct power supply ie as shown on page 1-19 of the manual.
You need the ATX12V1 connector as well as the normal one.

DUH. I can't believe I missed that. Thank you Geoff.
