System time wont update P4C800-E, seconds wont tick

[Ian]

I have a new p4c800-e mobo installed for a friends pc, but I cannot
set the system time in the bios. I can tab over it and alter the
numeric values, but it remains static even after a save and reboot. If
I adjust the windows clock (xp sp2) it will change the mobos time, but
the mobos time remains static and will not "tick on", hence a shut
down for a few hours looses a few hours on the bios clock which then
affects the windows clock,.I have changed the battery to no avail and
flashed the bios. Please help its driving me mad.
I have one of these boards in my pc and you can see the seconds tick
on in the bios display screen, so why wont this do it?
Every thing else works fine

I have never heard of this happening, but it very much looks like a
defective CMOS clock. I'd return the board.

To the right of the Southbridge, you'll see a silver colored
cylinder. That cylinder is a 32.678 KHz watch crystal, similar
to ones used in wrist watches. That is used by the Southbridge
for timekeeping. Perhaps the crystal is missing ? Or one of
the two tiny capacitors used to compensate it.

Page 67 of this document shows the essential components.

If the cylinder is there, tap the cylinder and see if the clock
starts to run. The crystal itself could have a bad connection
(sometimes caused by a shock received during shipping).

HTH,
