New Machine won't Post

New Build PC

Asus P5K
E400 intel CPU
2 GB 6400 ram (compatible according to both the manual and Asus' ram checker)
Antec Sontana III case (500w power)

Asus P5K motherboard (1.02 motherboard version so should work with a 45nm processor)
E8400 CPU
BFG 9800 GT video card
Corsair 6400 800mhz ram
Antec Sontana III case (with 500 PSU)


When I have everything connected and power on, nothing happens, the cpu fan goes as if it was about to spin but then just stops without doing anything but slight movement.

If I remove the Ram, same as the above - no Bios Beeps

If I remove the video card then I get the 1 long, 3 short for a fault with the video.

Yes the 2x2 is connected as well as the main supply to the board.

Processor+Ram+Video Card=nothing
Processor+Video Card=Nothing
Processor with no ram/video card=beeps for no video, fan spins
Processor with ram, no video card=beeps for no video, fan spins.

Do you have an old PCI-E video card, even a very old PCI one? It seems that the video card may be causing the problem. Or possibly the mobo's PCIE-16 slot or PCI-E bus.

Only AGP, no PCI unfortunately

It might be the PSU I suppose, do you have another one you could try?

One other possibility. Pushing the video card in is flexing the motherboard and causing a short againt the case. Seems unlikely though. You could try putting it together outside the case on a cardboard box to remove that possibility.

Otherwise did you get motherboard and video card from the same supplier?

I tried taking it out and putting it on cardboard - same outcome.

I don't have a more modern PSU unfortunately, not one with a 24 pin connector.

Everything came from the same supplier.

Ring them up and get an RMA then. I'd return all the main parts (PSU, CPU, RAM, Mobo, Video) just to be sure.
