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.
Best,
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.
