Is my mobo DOA?

Hi folks, put my first system build together today and when powering
up for the first time I got nothing but the green led on the mobo.
Nothing else on the computer turned on fans,lights ect.. Here are the
components.
Pentium 4 3.2E 1mb cache
Asus p4p800-E deluxe
Seagate Baracuda 120 gb hard disk 8mb buffer
Plextor px 708A dvd-rw
Crucial pc3200 512mb DDR Ram
Ati Xpert 2000 pro AGP video card
400w power supply that came with my Light-on case "Sun Cheer"
12v=15A/5v =35A/3.3v 22A and it's p4 ready

I unplugged my system piece by piece until it was just the CPU and Ram
and I still could not get any power to the cpu fan. I also reset the
CMOS by moving the jumpers with the battery out but that did not work
either. I also tried to power up with the mobo outside of the case
which did not work as well. I plugged and unplugged the power and fan
connectors too..

As I mentioned the green led on the mobo lights up when I hit the
power switch but thats it.. Is this mobo dead? Any suggestions would
be appreciated.
Thank You,
Martin

Will the PSU turn on if you ground the signal wire?

Not sure how to ground the signal wire but I did search the newsgroups
and found a way to test the power supply by shorting pins 13 and 14 in
the 20pin ATX power plug. The fan on the PSupply finally ran. When I
plug into the Asus Motherboard the green power led goes on but that's
it, the fan in the PS does not move.
Thanks,
Martin

Problem fixed, I learned that you must have the power switch (power
sw) connector plugged into the panel of the mobo. I thought the power
supply on/off switch served the same function. Lesson learned... Once
I connected the the power sw and pressed the button on the front of
the case my My asus p4p800-E deluxe came to life!
Thanks for your advice,
Martin

One last thing, short the power on switch pins on the mobo to rule out a bad
case switch. If nothing happens then, RMA the board.

Hate to say it, but I *really* believe that Asus has a quality control
problem with the latest boards. I got the same one you have, and it came
with two dead fan headers...only the CPU fan header worked. Likewise I
assembled just about everything until I discovered the dead headers...RMA'ed
it and got a different brand. Maybe you will figure this one out, I hope so,
but I'm staying away from Asus for now. Asus will tell you that your board
is grounding out if you call them, as they *do* have that problem with some
erractic large solder joints on the bottom of the board that can be shorted
out.

Good luck, and maybe someone will offer a good suggestion.

Isn't it a good feeling when it comes alive? 🙂
