Beep code sound familiar?

Hello,

I just put a Biostar M7NCD Ultra into a "generic" (Acer type, but not Acer)
case. It appears as though everything is plugged in properly, but...

When I go to power the machine on, it does, initially, but very briefly;
then it powers off and lets off this constant beep code, that goes something
like:

beeeeepBEEEEEPbeeeeepBEEEEEPbeeeeepBEEEEEPbeeeeepBEEEEEP...

....the "beeeeeps" and the "BEEEEEPS" being one octave apart. It stops
beeping about 3 seconds after I unplug it.

It's an AMD Athlon processor in a 462 socket. The BIOS is Award Legal
APM1.2.

I checked all of the connections, re-seated the RAM and the processor, no
go. BioStar's manual sucks, and there's a questionaire about 1/2 mile long
that has to be filled out in its entiriety before they offer any email
support.

Anyone know anything about this?

Thanks, in advance,

smackedass

Have you got a video card that needs a power connection?

Could be CPU overheating! What CPU? What cooler? Make sure Cooler is
correct way round on socket, there is a 'step' on the base of heatsink which
has to go against theplain plastic strip beside CPU. Will not make good
contact if wrong.

First, give us a concise but complete description of the
system. All major parts including PSU make, model, and 5V
current rating.

The board uses 5V rail for CPU power, so it may need a
better than average PSU.

Try clearing CMOS.
Does your CPU fan have an RPM signal output, is it running a
least high enough to be discriminated by *most* boards
(typically above roughly 2000 RPM on some boards), and is it
plugged into the correct fan header for CPU?

What's the history of this board? Had it worked for you
previously and if so, what has changed since then?

Remove the motherboard from the case and lay it on it's box or something that is not electric
conductive. Try it now. Are you sure it is grounded properly in the case. I have seen some cases
that motherboards do not ground properly in because of the mounts that the motherboard get screwed
into. Eliminate that possibility by removing the board from the case and give it power. No drives
should be connected. Just board, cpu, mem, use onboard vga if you have it.

Thanks to all who have responded.

I simply removed the mobo, re-tightened all of the screws, this time being a
bit more attentive to how evenly they were screwed, and all was well.

I never realized that mobos were this sensitive..

Thanks, again,

So, I was correct?! Glad you solved the problem.

you may or may not have been right, it might have been
shorting out on something (like an unnecessary standoff),
but "evenly" screwing in all screws is not a valid solution
as it does not address any possible failure mode nor
scientific reasoning.

It could even be something barely related like a cold solder
joint barely making contact if a certain board tension is
maintained, but there is definitely no requirement to torque
all motherboard screws to any particular degree, they merely
have to keep the board isolated from the surrounding parts
so far as funtion goes on an otherwise properly working
board.

The nice thing about intermitant problems is that they always come back
and you can try again.

??? Maybe you're joking but if not I strongly disagree.

If it's not intermittent you can keep looking as problem
persists, or has stopped forever and thus no problem
remaining.
