Many varieties of anti-static bags, including all of the ones I've seen motherboards placed in, are actually slightly conductive. They have to be in order to produce their anti-static effect. I would suggest you just use the cardboard box that the motherboard came in.

I figured I'd try this first since it seemed simplest. I turned on the power and nothing happened. I guess its time to send the PSU back.
take the board out of the case, and just run the motherboard & CPU from the power supply

You should get beeps/LED errors for no RAM and or no GPU. Assuming you get that far give it a stick of RAM and then try again. If that works, give it a GPU and it should POST.
This test is foolproof, and it'll take you less than 30 minutes:
Step one narrows it down to a PSU/Motherboard/CPU fault.
Step two identifies faulty RAM.
Step three identifies a faulty card.
If you get it to POST out of the case and it doesn't work when you put it back in the case, you know there's a short in the case somewhere. Viola, problem solved.

When I connect my SATA cable from my hard drive, I got the same problem I had before - the mobo turning off. I tried both of the SATA cables I have and each of the SATA2 and SATA3 ports and no matter where I put the HDD, the mobo quits.
I have a SATA optical drive that doesn't kill the mobo no matter where I put it, as long as the HDD isn't connected. So what do I do about the hard drive?

Chrispy_ wrote:So the SATA hard drive causes a POST failure and a SATA DVD drive on the same port/cable POSTS ok?
It's the first time I've heard of an HDD stopping a machine from POSTing (drive detection is usually not until partway through the POST)
As others have said, a serious short or electrical problem with the drive could be playing havoc with anything it's plugged into. Try another drive!
