ABIT MB AS8 - Cannot Boot: PCD=9.6 De-assert CPU Core voltage

[Toto]

Hello there! How is verybody doing in this back-to-school times?

OK so here is the situation I am faced with. If you had a similar one, I
would love to hear how you solved your problem. By the way this is not hte
first time I am assembling a PC form scratch.

I bough a AS8 Abit Mother board and a Pentium 4 CPU (2.66 GHz, 533 MHs FSB,
1 MB L2 Cache). After I have finished connecting everything, power-up, the
boot sequence starts but within seconds, the Speaker makes several unsual
long beeps and then the Motherboard shutsdown.

If I look at the AC2003 PCD (Post Code Display) on the mother board, the
code I see just before shutdown is : 9.6. When the MB is fully shutdown then
the PCD reads : 9.F.

Any clues, suggestions?

Thanks for the help.

Regards,
Manuel

How many beeps? If you're manual doesn't have the info, there are a few
websites that can tell you what the beep codes are for your BIOS.

Check that heatsink is installed properly. Check voltages
with a multimeter if possible. Next remove/disconnect all
devices non-essential to POST, disconnected from both
motherboard and power supply. Remaining connected should be
board, CPU, heatsink/fan, 1 memory module, and video card.
Turn on system by shorting the two power-on pins together
carefully with a screwdriver tip or other conductive metal
object.

With above config, of course you can't boot but see if it
stays turned on. If so, connect keyboard and turn system on
again, this time entering into the bios menus, the hardware
health/monitor (or however it's worded) page and note the
reported voltage and temp readings. If this seems to be a
power supply or component problem, add parts back one at a
time and then note the voltage reading again.

Your post codes may not be revealing, often a board stops at
a code, not shutting down so for the time being I'd focus on
things other than the codes.

Dawg, Kony thank you for helping me out.

Conor, Dave thanks for helping resolve my problem.

I got the solution and this is somewhat embarrasing. My problem was as
simple as a cable not properly connected...

When I installed the new AS8 board with a P4 pentium I was actually
upgrading from an older mother board with a Celeron CPU. This mother board
had only ONE powersupply connector (the 20 pin connector - ATXPWR1). Howver
the AS8 requires 2 feed and thus two connectors: the 20 pin ATXPWR1 AND the
4 pin connector ATX12V1.

As soon as I plugged in the second power cord, my problem disapeared.

My upgrade is now complete and my daughters are using their new PC.

Manuel

Thanks for not bringing a fish in a newspaper.

Thank you for taking that philosophically.

YOU KNOW THIS IS A SIDEWALK. YOU SHOULD CLEAR THE WAY.

What about your mother?

The whole world is my mother.

And you don't even wonder why?

Why is it a problem?

So, is your daughter coming home for Easter?

You don't have any friends you can talk to about these things?

I always get anxiety and panic attacks right after eating.

Neat trick, Toto. Embarrass yourself in front of everyone; that'll teach 'em
not **** with you, eh.
