So here's my problem. And it's only been on this one computer, I have built about 14 computers from this same wall plug and area in the last 4 months,no issues at all.

I have a Corsair Air 540 case, i3 6100 with an Asus h170 plus board,with a SSD drive, and all the typical things that go into a computer. I'm using a EVGA 600 bronze certified PSU.

I noticed it when I was plugging my portable hard drive into the front panel. There was a slight static discharge and the screen started to wig out and flicker, nothing would do anything so I had to hold down the power button. Tried it again, same thing. Walked by and touched the case, not the USB, and computer turned off completely. Tried it again, same thing. I tried a different power supply thinking the other one had a bad ground, a 500 watt EVGA bronze. Same thing. Moved computer to a different room and different power surge, same thing.

Unplugged the USB 3.0 connection up front, same thing. You should be able to touch the case or plugging a USB device into the machine with no issues.

Would a bad mobo do this? The PSU should provide the ground for this not to happen,but it is on two different PSUs, one with a known good hardware.

I have someone going to verify that I have a good ground in my wall sockets tomorrow.

What do? Any suggestions?

Something isn't grounded somewhere in the case. Start pulling stuff out and disconnecting what you can one by one and see if you have the problem. If it's just touching the metal of the case, it's a ground somewhere with something touching the case. If it's only when you're plugging something in then it could be a defective case and that front panel is getting energized somehow.

Pull out the power supply and keep it away from the case, see if it still does it. Try with the hard drives outside of the case, then try with any other things like CD-Drives, network cards, GPUs, etc.

If it's still doing it then it's definitely the motherboard. Try to take some pictures of the inside of the case and around the case if you can.

Did you use the motherboard standoffs?
It sounds like nothing was grounded and the entire system got shocked.
If the USB device caused it, the power supply wouldn't matter. That shock would have went straight into the motherboard.
If your motherboard wasn't grounded/you didn't use standoffs or something of that manner, then it's likely that the board is fried.
Do you hear any posting or beeping when you hit the power buttons?

The wall power doesn't sound like the issues, just like it's not the PSU. It sounds like the motherboard wasn't installed properly and wasn't grounded.

No I even took the board out, ask the standoffs ate being used and there aren't any in the case that aren't being used, so no shorting on that. The computer restarts every time just fine.

The issue is not the restarting, it restarts into windows and loads no problem. It's fast, responsive, everything on the restarts is fine. It's the static touch issue I'm having. Out of all the builds I have ever done, this is the first time I've ever ran into this issue.

When I reinstalled the motherboard, the screws are nice and tight, and the correct screws.

No, I can make it restart religiously by touching it with a static build up. About 7 times now. I try something new, eg, PSU, and test to set if that was the issue and so on. I'm not wanting to "test" this too much, I know it's running the risk of frying everything.

I'm going to remove the board tonight and inspect for any fractures on the board itself. I have not been happy with this motherboard since I got it. For Asus, it's lacking their normal quality control. The board has a noticeable flex to it if you hold it on each side, the heat sink on the chipset was upside down. Wondering if I have a bum board.

So I can get up, walk to the shelf about 5 feet away, get a thumb drive, go to the computer, plug it in and then it will happen. Sorry should of said this earlier, but if I ground myself before i touch it,then it's fine. I can use everything no problem. Regular walking to it, not trying to build up anything out of normal, will get a static shock enough for it to wig out. I love in Colorado, and yes we have a ton of static here, this computer will be shipping to Oregon where there is not a lot of static. But I can touch any of my other computers in the house, and there is a lot of them, and no problem with then at all.

The only thing that looks remotely close to touching the motherboard, is the back panel cover, it seems very close to the motherboard. It's a steel back plate, and it is secured in he cut out as deep as it can go.

But I'll do just that, and start to take some things out and test it.

Thank you for your speedy responses.

You'll want to be looking for anything that is touching the case that shouldn't be.

EDIT:
Look for charing like this: http://i.imgur.com/wLrHQrY.jpg
Make sure that the screws are tied down flush in these spots: http://www.dragonsteelmods.com/Images/reviews5/nzxthades/resize/Hades35.jpg
Make sure your standoffs are screwed in as such and are between the motherboard and case: http://cdn.overclock.net/1/18/18d7c90f_standoff2.jpeg
Make sure that if you have back plates they are not hitting the case:

Also, when inside the case make sure the PSU power switch is flipped to the off position to make sure you don't take any voltage in case it's being energized and ground yourself
