P4P800 boot problem

[tailgunner82]

Having a boot problem with a new bulid P4P800. After power on I'm getting nothing from the MB. No BIOS messages, no keyboard flashing, no beeps of any kind. Fans run and the green light at the bottom of the MB is on. I do have the 12 volt 4 pin power connecter hooked up to the MB. Any ideas on this? Bad MB, CPU, power supply? Any way to track down which could be bad? Nothing visually wrong as far as I can tell. P4 3.02

I'm having the same problem as you with my P4C800-E, but no one has responded to my post either. My assumption is a dead mobo. If you get it working again, i'd like to know so i can try it on mine.

Do you have speakers plugged in? The ASUS post reporter will give you a vocal message, which while not always correct, will at least give you a starting point.

Hi Dejiko, Have no idea what it is. I'll let you know what I end up doing. Doing to replace the mobo first if I have to.

Hi klc314, I didnt have the speakers plug in. I did have the case speakers plugged in and didn't get any beeps at all. If something other than the mobo was bad, I should have heard some type of beep code?

I had that problem with a p4c800-e and it was a dead motherboard. Luckily the new one works fine.

I was reading here http://www.tech-forums.net/computer/topic/6106.html that it maybe a mounting problem. I re-installed the CPU and mobo into the case, but same problem still. It seems this is a common problem with Asus mobos, cause i did a google search and found several links to the same problem on other boards made by Asus.

Im not at all bashing Asus, I have a CUSL2 P3 Mobo and it has worked without fail for 3+ years now so maybe its just a bad production run or something

he case speaker won't produce the post reporter, it takes speakers plugged into the speaker output. You will hear a voice say something like "system failed memory test". I think there's about 7 or 8 different messages of errors preventing full post.
