Well, all my stuff arrived from NewEgg on Friday. Went to work putting it all together. Had it set up, sides were still off the case and wires everywhere, but I figured why bother with cable management until I know it works. Well, I hook up my monitor, keyboard, mouse and fire it up. Blue LED lights all working, fans all humming. From the monitor, "no signal." I check my cables, make sure the vid card is seated properly, retry. NOTHING

And I'm thinking, Oh my god. I just bought nearly a thousand dollars worth of computer equipment, put it together the best I knew how following manuals and online tutorials and I don't even get the proverbial screen of death. I mean, I don't even know where to start looking for my problem.
I pack everything up and stick it in the computer room. We go to pool and I run into a guy I know who builds computers. I've had a few and I'm really upset about the thing not working, I'm panicking because I don't even know where to start looking for my screw up and I tell him I'll give him a hundred bucks if he'll just come over and get it going.
Next day, this morning. Wife is going for her hair appointment and I tell her, well I'm gonna work on it a little more, see if I missed something. Yesterday, when I start unpacking all this crap and there's boxes, screws wires, etc. everywhere, she and her freind say, "Are you sure you know what you're doing? You know you're not mechanically inclined." So she just kind of looks at me and says "OK" which means I told you so.
So I bring it back into the living room on the coffey table. Flip it on the side and start looking at the mobo for any missing connections, specifically power connects. I see one on the corner close to the heat sink. An 8 pin connector. I look at my PSU. Have no 8 pin connectors, but a line with two 4 pin connectors that are obviously supposed to be coupled. I look at the mobo manual. Sure enough, there is supposed to be an 8 pin power connection that powers the cpu. I plug it in, make sure everything else is right and fire it up. Thing starts loading and a minute later I'm installing my OS

Yes, I am the man!
However, I'm the man that knows nothing about ocing, will appreciate any advice on how to go about with evga 780i mobo and e8400 cpu and 4g of ocz reaper ram(DDR2).
