It is ironic that just a while ago I was going to post here that I couldn't
get my newly built PC to power on. It turned out that I just had the power
switch connected to my motherboard the wrong way.
Now when I press the soft start button on the front of the case it does
start up (case fans and cpu fan start up) but when I press the button again
to shut it down, it doesn't shut down. I have to use the switch in back of
the case connected to the PSU in order to shut down.
Does anyone know the cause of this.
FWIW, the MB is a p4c800-e deluxe and the case is an Antec plus1080AMG
Also I don't have any periphery attached nor have I installed an OS yet if
that means anything.
Thanks in advance for your help.

Look in BIOS settings for Power Switch or similar..
Options are usually something like...
Disabled
Instant On/Off
4 Second Delay (hold power button in for 4 sec.)

If not that, u got me. ;p

Once the OS starts loading (that is, a windows OS) then you'll find that the
ability to simply press the power and have the system go off is disabled.
If your in say grubs boot loader then yes the power button should work. So
there ya go..
 
To shut the machine Down, did you correctly push the power button in and
HOLD it for 4 seconds as required?

This may have nothing to do with your problem but once I had a new build
(windows 2000) that refused to shut down. It turned out to be a driver
(I think is was a modem or NIC) that failed to fully load from the
initial OS install. It showed up as an exclamation mark in the control
panel, devices. Once loaded it shut down fine,

That's the correct procedure for a "soft shutdown". It's normally used
after a hard freeze that can't fixed by closing the offending
application with task manager. It's considered better than a reset.
