Hm, this must be a cliche I haven't heard :D

Perhaps it's the momentary switch that PCs use for power down?


Doubt it. I've tried 3 cases with different switches.

I've tried 3 cases... with and without the power switch connected to the
motherboard... 20+ times.

Yes.

No idea if it will help, but you could try your current setup but

I can :)

If the machine now stays up, perhaps try swapping out

Thanks bb. Basically, since I've done *everything* possible to test this and
spent 40+ hours with this issue (last week) ... I have decided to just use
it, and not force static. So far, I have had no issues... plugged in USB
devices, accidently shocked it a few times... etc. I think it has only shut
down on me once. I'm going to live with it since I've ruled out all possible
variable I can think of (for the most part) ... and no one else (50+ people
not including SGVLUG) knows what's going on. Since I've ruled out all
variable and no advice has solved my problem, I've decided this was the luck
that was thrown upon me from up above - and I must make do. :D
