The post beep sequences are not common between different MOBOs.

One sequence can mean no graphics card detected and another sequence can
mean no CPU available.
I double that there is any problem with the MOBO itself.
You need to find out what the beep sequence you are hearing means for your
MOBO,

"Clark" - the person you actually replied to, not the person you
THOUGHT you replied to - provided the proper link for determining the
meaning of the beep sequences on HP computers with a Phoenix BIOS.

Everything was working fine until the post error began. The POST error:
one short beep followed by one long beep, looping until
I turn the computer off. I tried replacing the RAM, pulling out all of
the PCI cards etc.

The computer runs a Phoenix BIOS modified by HP. The mobo is an Asus
built HP board:M2N68-LA (Narra2). I researched the error a bit and came
to the conclusion that the motherboard went bad. There have been no
surges & no visible damage to the board. I want to know why a mobo does
this for no apparent reason.



I suppose you have gone through the steps at the following site:

What did you change originally just prior to the failure?

Have you tried unplugging the power supply? Have you checked all the
motherboard connections, especially things like CPU fans? Did you loose a
screw or some type of hardware, maybe something is shorting out a
connection.

Does this motherboard have built in Video, and if so can you add a video
card?
