Newly Built Computer (Asus P4PE) Will Not Turn On HELP!

[BMW330ci]

Hi guys,

I helped out my friend build his new rig - Asus P4PE, P4 2.66GHz, 512MB Kingston, new case, hard drive, and videocard together however the computer will not turn on. The fans don't spin, no beeping noise, just nothing.
I've tripled check the power switch pin and ensured it is in the correct location of the motherboard (I have the same mainboard with no problems). Is this a defective motherboard? I've encountered this problem before but that was due to the power switch pin being upside down but I'm positive it's inserted correctly this time. Is there other things I've missed? It's not the case either since we plugged in the power switch pin on another motherboard and it turned on.

Thanks alot for your help!

Can you try another powersuppy?

Check that the cpu is properly installed and seated correctly

Thanks. I just checked the CPU and it appears to be seated properly.

The power supply (350W) appears to be providing power to the motherboard because the green light is on when I turn on the power supply. But I will try another power supply.

Thanks for your help.

Any other possible causes?

People here often recommend trying the mobo out of the case. It is surprising how often people put an extra spacer or something behind the mobo which shorts it out.

A lot of people pull out all the cards including the video, and unplug all the drives, to eliminate as many possiblities as they can. The mobo should still beep when powered on.

It is possible that some mobos may not boot up if the CPU fan is not plugged into a certain header.

Resetting the CMOS is always worth a shot.

Thanks. I will try those procedures. I did try clearing the CMOS and double-checking the CPU fan.

One thing and the only thing that will work to fix the problem is to take everything out.

Leave only the cpu, heatsink, RAM, and videocard. unplug everything else!

the typical things people forget are:

1) plugging in the power switch from your case to the motherboard
2) plugging in the cards half way in - take out all your card and reinsert them one at a time until your ocmputer no longe robots. that card is either not seated right or has something wrong with it.
3) memory not seated right
4) switch on the power supply is off - flip the switch on the back to on if it's off.
5) plug the computer in the power outlet
6) make sure the cpufan is plugged in the appropriate fan header. Some motherboards list what fan header must be used for your computer to turn on. Typically it's labeled on your motherboard as "cpu fan" around the header.
7) NOT reading your manual! Please read your motherboard manual!
8) Make sure the proper jumpers are set ebfore turning on your computer
9) When it starts to boot - make sure you enter your bios and make sure your settings are correct for your hardware

Tons more people forget but i'll be here forever!

Thanks. I will try some of those procedures although I've eliminated some of them already.

i had the same problem with my p4pe. i had installed an extra stand-off behind the board ,shorting it out. im lucky i didnt kill it. it wasn't my first build either. just a thought.

Thanks for your suggestions guys. Looks like the 350W power supply was the culprit! I swapped my Antec 430W and the system finally turned on!

Thanks again for your all your help!
