Gigabyte 8KNXP motherboard makes the built-in speaker continuously buzz

I have just built a PC with the following new hardwa

Gigabyte GA-8KNXP Motherboard
Kingston 1GB 400MHZ DDR RAM
Intel Pentium 4 2.8GHz 800FSB SKT478 512K cache CPU
Maxtor 120GB SATA Hard Drive
GeForce FX5200 AGP8x 256MB Graphics
LITEON 52x24x52 CD-R
LG 16x48 IDe DVD-ROM
Sony floppy

The PC has Windows XP Professional installed on it, everything works
fine and the system boots up with no problems. The only problem I have
is a constant buzzing sound coming from the built-in speaker that is
inside the PC's case.

The buzzing sound starts as soon as the PC is switched on and does not
stop. I have removed each piece of hardware that is possible to try
and diagnose why this is happening but cannot cure the problem.

Can anyone give any reason why the problem should occur accept for
that the motherboard is faulty which is what I have already been told.

Thanks.

Phil.

Have you tried to flip the connecting wire around, the one that leads
from the speaker to the motherboard to the motherboard? Maybe the
polarity is switched.

I've already tried that but it did't change the output.

Try disabling the onboard speaker in the BIOS.

There is a very good chance that the regulation and / or filtering in the
power supply is either failing or below industry standards.

In this situation I would try replacing the power supply with a unit from a
good manufacturer. Antec is a good choice; others in this newsgroup have
also spoken highly of 'Sparkle' brand power supplies.
