I recently set out to finally buy and build myself my very own PC. Something I've wanted to do for a while, but I've hit a wall here. After hooking up everything, my motherboard, my GPU, Power supply, all of it, the computer absolutely refuses outright to display on any screen it's hooked to, in any basic way, shape, or form. I was looking to see if it may be something to do with my GPU, but After looking into it, the way I have it wired up should be fine. I have no idea what I'm doing wrong and am absolutely confounded. Components are an EVGA X79 Classified motherboard, MSI GTX 760 TwinFrozr, And My Power supply is a Corsair CX600 M. I've seen some people say that when wiring a 760, you need two separate cables going from the PSU to the GPU, but I've also seen that if you have one cable with two ends, you can use that and it will work just fine, which is how I have it wired. 8 pin out of the PSU, and 2 6+2pins going into the GPU. Any ideas?

Yes. I also don't seem to notice an onboard port anywhere on this, although I could be overlooking it. I was thinking about looking into the CPU since that was the one part I didn't directly install myself. A friend wanted to do it and he assured me he knew what he was doing/had done this stuff before. Worried I opened a box of regret when I let him do it.

Edit: I forgot to mention it, but I have followed every step on http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems twice, broke down and breadboarded the PC two times and still nothing. And while I do have a Case speaker, it's not doing anything. I'd hate to find out I spent all this money just to find out something in this is DOA. I'm going to check the CPU pins one more time to be positive none of the pins are bent up, but otherwise, I have no idea what to do.

Okay, Oversight on my part, but I've made progress. the default Bios for the mobo doesn't support my processor, but I'm reading that I can update the bios via a flash drive to add full support. My only problem is, I have no idea how to do this without a screen prompt or something to see.
