i think there was an updated bios for that board released in july 2005 to resolve known problems, i am not sure if the problems relates to your issues.
P4P800 SE no go beep
I've got a system sitting here that isn't behaving, and I can't seem to find out why.
Asus P4P800 SE
Nvidia Quadro 750 XGL
*NEW* Allied AL-A400ATX 400W
2gb DDR
40gb maxtor
Win2kpro
etc..
The problem here is that everything has been set up properly as far as I can tell, jumpers are good, connections are good, yet the system won't boot up. We get no beep, no bios.
The computer went from working one day, to not the next. I found out that a big problem was the power supply being horribly underpowered. So I ordered a new one and put it in, we get power and fans spinning, but it wouldn't boot. So then I swap out the processor and the ram and there's no change, so I send the motherboard into Asus for repairs and they return it saying they have fixed it. I just put it together again and the behavior hasn't changed. I must be missing something here.. any ideas?

How do I update the bios when the computer won't even boot to the bios?
i think you should remove the system and put the board on a sheet of cardboard
do a build "out of case"
jump the on/off pins on the motherboard with a paperclip
you need to eliminate the thought of a short
also possible you got a new faulty psu

The power supply worked fine in another computer I tested it with. I'd rather not take it apart again either :sad: let's leave that as a last resort.
Hmm Allied PSU: wonder what the problem could be [email protected]!!

Thanks Whodat / for the link !!
A PSU is not cleared of being a suspect until you try it in another system or equal volatage draw or more !! I have several customers that have brought me P4 systems that were buggy because of PSU problems and told me "it cant be the PSU I tried it in another computer and it worked !!" when I asked what was the specs of the other computer they answered " P3 -733"
thats not a PSU test for a P4 by any means
sounds like you have a weak PSU that doesnt have the amps required by BOTH 12V rails
By Enermax or Antec / they are both quality PSU's for affordable cost / about $100.00 check ebay and newegg.com
cheers

Unfortunately we are required to order all of our hardware through a certain provider. This PSU is pretty much the only p4 400W I could find, crap. I'll see what I can do, thanks for the suggestion.

I can feel your pain dude !! Our office does the same thing !! you request a PC componet and some twit in purchasing gets assingned the job of buying the component ~~ yep you guessed it ~~ they buy the cheapest crap they can find and we just keep swapping it back to them until they finally listen and get what we ask for !!
aint work fun !!

Ok after a decade or so our power supply arrived. I got an Antec True430. Mobo still no go beep. I'm glad I got the supply anyway, though.
well now is time to check for a mobo short / you will need to remove from case and set-up on a piece of cardboard and run the bare bones / no drives at first
how about ram / have you tried to put just one stick in and boot with that ???? check to be sure (see manual) which memory slot needs to be occupoied for single stick config.
let us know / we WILL slay this beast

I read the manual previously and tried to run it using a few different sticks to test if any ram was bad. No matter which combination I tried the motherboard emitted a loud rapid beeping noise at me if I tried to start it up (might this be bad?). I've swapped out every other component as well. And I ASSUMED the mobo would be in working order since Asus just sent it back to us claiming they had fixed it.
I'm going to wait for 1 more reply before I consider taking out the stupid motherboard again. :smile:

Is the stock Intel Heatsink installed on this board?
Some of the ASUS boards have an issue with the stock heatsink being so tight that it crushes solder joints together under the heatsink retainer support bracket on the back side of the mobo. This causes no post/no video on these boards.
This occurs on the P4C800 series boards but I bet the P4P is the same design with a few minor differences.
You might also try connecting a meter on one of the 12V plugs and starting the machine. If the voltage drops allot when the machine starts then your sucking more amps than the PSU can deliver. This could be caused by a short, bad component or weak PSU.
You could unload the PSU some by disconnecting all the drives, removing all the cards except the Video card and see if it posts.

I tried taking the motherboard out and powering it up with nothing but the gfx card and ram just to see if the bios would show up, nothing. The CPU fan spins but it never gets past that. Yes it has the stock heatsync, but as far as I can see there are no solder joints crossing on the back of the motherboard. It appears very unlikely on this model.
Would Asus have sent us the Mobo back broken?

I went ahead and swapped out every bit of hardware with known to work pieces again. I only have the ATX power wire plugged in from the case, and the psu hooked up. Still no go.
Hello:
what is the status of your CPU & fan / when you power the mobo on do you get cpu fan spinning ???? if the video card has a fan does it spin ????
is the mobo little green LED light on when mobo is not powered up ?????

when you say you only have only
I only have the ATX power wire plugged in from the case, and the psu hooked up. Still no go.
you should have three wires connected to mobo or it wont fire up
1) 20 pin main mobo connector / look at end of PSU and mobo connector body ~~~ see any burnt pins ?????
2) 12V power plug from the PSU / with a latch read your PSU manual carefully / the correct 12V (4-pin power) cpu wire has a yellow wire with a black stripe as one of the four wires in the 4 pin power ?????? is this the one you used ??????
3) cpu cooling fan must be connected to cpu fan location on mobo ?????
let us know what you find ??????

I only meant that i left the 'HDD LED' and 'SPEAKER' type wires disconnected, because they don't matter. If I connect them I get no changes anyway.
Cpu fan spins, gpu fan spins, led on the motherboard to indicate power is lit as long as the psu is switched on.

Sounds like its time to RMA your mobo
the power led on the mobo should stay on all the time / even when power supply switch is off / it stills puts enough power to the mobo to maintain the cmos settings
