I am at a standstill on my checking.
Would there be any danger in using a second known good psu and just
plugging in the 24 pin main supply cable and leave the HD power on the
old power supply?
This would show up if there was a break in one of the power wires in the
old power supply without just changing ir all out.

Sam,

IIRC, if you jumper pins 15 and 16, you will do the same thing the m/b's
internal switching logic does to turn the system on. Please do not hold me to
my choice of pins. Others in the collective have much more experience with this
and may offer other choices of pins.
And, in all truth, I have not really seen all that many true internal wiring
problems in modern PC cases since ~1975. I have only seen one m/b whose
internal switching logic went bad or died. I would focus on the m/b ground
logic and/or the psu. Jumpering the 24-pin power connector should really be a
last ditch kind of trial.

Thanks,
Do you have any idea what pin on the 24 pin power connector provides the
connection to turn on the power supply.

Sam,
I have found that this problem involves at least 2 things.
One thing is the m/b itself............
The other thing is that internal case wiring.
For the m/b, what you need to do is make certain that the m/b is tight (?) to its' tray.
Or, make certain that it is screwed down tight, however. It is most probably a
"ground" thing.
Next, case wires and their looms are notorious for problems. Stuff just
happens. Your off/on switch could be fine, but the signal is not making it to
the m/b due to bad wiring. A Look/SEE.
That is the best I can share.
I do not know Gigabyte m/b's. I have never seen an Antec case.

Duncan

I have an Antec case with a Gigabyte mobo that has a strange boot operation.
If I press the start button and it doesn't boot, I turn the case on it's side
and it starts.
I can turn the tower back on it's base and it continues to run fine.
I turn it off for the night and it may start fine in the upright position or I
may have to turn it in it's side to get it to boot.
I have replaced the start switch with no difference in operation.
What voltage should be across the start switch terminals?
Any ideas of what to explore?
I know this is a crazy problem with no obvious exploration paths.
