NO POST - MO? CPU? DIMM? AGP? KEYBOARD?

THanks to all for their suggestions

I hooked up an earphone to the motherboard and listend as the system
started up --
it said " CPU failed" -- so i replaced with a working CPU but same
message as b4
SO it can't be the CPU... looks like the motherboard is fried .... is
this normal
should it say that the motherboard failed? or this is just a flaw in
the Asus
motherboard .... all across all motherboards?

Thanks

Unplug the power, remove the memory sticks, the video card, keyboard
and mouse. Listen to the Vocal POST. Does it still say "CPU Failed"
with just the processor installed in the motherboard, or does it tell
you there is a memory or video problem. If memory or video, plug in
one memory stick and repeat. If it complains about video, then the
memory must be a bit functional. Now plug in the video and power up
the machine again. Does it complain about the video or do you hear
a message about "No keyboard" about thirty seconds after power up ?

By starting with virtually nothing in the machine, you can use
the Vocal POST responses to suggest what is wrong. In each case,
the Vocal POST will return one of two answers, and that binary
decision helps indicate whether the latest added component could
be the problem or not.

With just the processor and the motherboard, if it is still saying
"CPU Failed", then something on the motherboard must be fried.

The Vocal POST chip cannot honestly say "Motherboard Failed". You
are overestimating the intelligence of the chip. The way that
the "CPU Failed" detection works, relies on a timer inside the
Vocal POST chip. The timer starts running just after the reset pulse
is removed after power up. If the CPU starts running the BIOS
code, early in the POST sequence the BIOS code clears the timer
in the Vocal POST. That would prevent the "CPU Failed" message
from being emitted. If the CPU is unable to execute the BIOS
code, or crashes after only a few instructions of the BIOS code
were executed, the timer inside the Vocal POST chip will expire,
and the "CPU Failed" message is generated when the timer expires.

The timer is used a second time for the memory test. If the CPU
crashes while testing the memory, then the timer is programmed
in the second instance to tell you about a memory problem. The
timer is used twice by the Vocal POST chip, the first time to
detect a failed CPU, and the second time, to detect that the
memory test did not run to completion. The CPU is supposed to
clear the timer a second time, just after memory test is
complete. All other messages in the Vocal POST, are actually
directly commanded by the CPU telling the Vocal POST chip,
which voice message to emit and when. So the missing keyboard
message, is actually detected by the CPU, and the CPU just
tells the Vocal POST chip which message to send to the user.

I interpreted all this, by looking at the source code that comes
with the Vocal POST reprogramming software, downloadable
from Asus. The source is not a high level language, so I
had to use my imagination.

I tried without the memory -- just CPU on the motherboard but still
same VOCAL message
"CPU Failed"
Looks like the motherboard is fried

Thanks

I decided to jump in with both feet and build this year's screamer. I
build a new computer every year or so, but this is the first one to
give me a problem in the POST department.

Here's what I researched and bought:

ASUS P5WD2-E Premium (manual says it supports PCG 05B)
Pentium EE 965 (box says it's an 05B)
1Gx2 OCZ DDR2-800 (OCZ2P8002GK to be specific)
1 ATI Radeon X1900XT PCIE 512MB
4 SATA2 250G drives (for raid10)
Pioneer DVD-RW drive
floppy drive
Antec Sonata II

Anyone see any problems with the above that I might have missed?

After putting it all together and connecting everything up, I switch
on the power supply and see the power led on the mainboard light up.
I then press the power button on the case and all the fans come to
life. Then..... nothing. No beeps.... no nothing. Monitor says no
signal on the DVI-D connector.

I power down, try the other video connector.... no change.
I power down, remove the video card, and.... no change.
I power down, remove the memory, and.... no change.

I built a very similar P5AD2-E Premium with a P4EE last year without
incident. Worked first time. Is there something obvious I'm missing?
I'm kind of at a loss over where to look next. Does the Sonata II
case not have a speaker? Could the BIOS on the mainboard not support
a 965? Could I have gotten a bad processor? A bad mainboard? Where
might I find a step-by-step guide to tracking down a boot/build
problem?

Thanks!
