Gigabyte GA-Z77X-UD5H-WB shorting when powered on?

[Obit11]

So I just bought a Gigabyte GA-Z77X-UD5H-WB (second-hand yeah so I should have expected it to be dodge). Regardless, plugged it all in. G.Skill Ripjaws X 8gb, i7 3770k, Noctua NH-D14 cooler, Thermaltake gold power 750w PSU and a GTX 560 se. Anyway, when I turn it on, it turns on, the MB and DB light flash one after another, then it just shorts out. After a few seconds it turns on and proceeds to do the same thing. The PSU is fine with my old Mobo and cpu. I have a photo of what looks to be an imperfection https://i.imgur.com/YI5m4CZ.jpg so I dont know whether that is the issue (part of https://i.imgur.com/7YF8M0t.png the bit in that is yellow)? I've tried turning it on with just the CPU power and Mobo power plugged in and it still does the same. (I dont have another PSU with 8 pin cpu power so I can't really test to see if my psu is to blame) Any ideas appreciated. Thanks.

I used to have one of those motherboards. The first one developed problems, under warranty, and it was replaced by Gigabyte. The replacement board developed an intermittent problem and was finally dumped.

I suspect you will have to replace the motherboard. If you can return it, do so. If not you are stuck with an apparent defective board.

The linked pictures don't help. One is blurry and the other is too small.
