Notice on your GPU pic, you only have one of two required PCIe plugs plugged in. I would check that out along with the checklist in this sticky...http://www.tomshardware.com/forum/261145-31-read-posting-boot-problems
The manual states that its fine using only 1. If you want to overclock, thats when you have to use 2.
And yeah, ive read everything on that sticky four or five times over.
Is there possibly a problem with the memory? It requires 1.65v, and I think DDR3 is defaulted at 1.5v... I tried using one stick to boot instead, but that didn't work either.
I am horrified to ask this, but is there possibly a broken component? Thats the most nerve shattering right now.
