Need some help with a fresh build!

Okay, so. I'll get straight to the point, me and a mate have been scratching our heads at this for the past like 2 or 3 days. Now before I continue with the problem at hand I'll reel of the parts I have.

Mobo - Asrock x79 Extreme 9
CPU - Intel i7 3820
RAM - 2 modules of 4gb Corsair DDR3 at 1600mhz
GFX - Nvidia GTX 560 TI
PSU - Antec 750 Wat High Current Gamer
And of course the other peripherals, but that's not really important at this current time.

We have put together this fresh new beast and the problem is, SHE WON'T BOOT. Dr Debug is displaying the error code 0x67 - "CPU DXE initialization (CPU module specific)". Now I have NO idea what this means. But I've determined that the processor is definitely getting at least some sort of power. We've thoroughly checked out all the other components to the best of our abilitiy (even threw in the GFX card in another computer and booted fine) so I think it's either the Mother Board or possible the CPU or possible the PSU. Any help would be GREATLY appreciated.
 
OK I think it could be your RAM. That CPU uses either tri- or quad-channel RAM (I forget which now), and it may not work with only two sticks installed. Try reseating or swapping the sticks around, putting them into different bays etc and see if she boots. Look in your motherboard manual and see if it tells you which bays to install the DIMMs in.

You could also try some of these too:

(try to boot the PC after you've done each one)

Firstly check to see the motherboard if power by looking for LEDs on the board, they should be on if the PC is plugged into power, even if the PC is not actually running. If no LEDs show when the PC is plugged into power and turned on at the wall on PSU, chances are the motherboard is dead.

1 - Check to see if the switch on the back of the power supply is switched OFF. If it is, turn it ON, hey presto, PC works! (this nearly ALWAYS gets me!!)

2 - Check to see if you have accidentally dislodged or forgotten to plug in your power switch wires into the motherboard! It's the simple things to look for first!

3 - Failing that, check to make sure everything is plugged in. Check 24-pin motherboard power and 4-pin/8-pin (depending on PSU and motherboard) CPU power connector especially. Also check 6-pin PCI express on graphics card if there is one

4 - If there is a floppy drive, remove it or unplug it.

5 - Start removing or reseating any extra PCI expansion cards such as modems, additional USB card, sound cards etc etc. Remove one by one and test to see if the PC will boot after you have removed. Eg - remove sound card, see if the PC boots, if it doesn't, remove modem, see if the PC boot etc etc.

6 - Start reseating or removing RAM sticks or try RAM in different combinations/bays.

7 - Remove or reseat any dedicated graphics cards and see if the PC will boot using the onboard video if the motherboard and CPU support it. If not, remove the graphics card, install it temporarily in a known working PC, and see if the PC boots with it installed. If it doesn't boot with the card installed, there's your problem.

8 - Remove the CMOS battery and reinstall it a minute or two after you have removed it

9 - Try another known working power supply or remove the power supply installed in your system and try it in another known working system and see if you get the same problem.

You must make sure you ground yourself before doing any of this stuff. Plug the PC into power, make sure the power is turned on at the wall, touch a part of the case that is bare metal (a screw usually works) and then you are done. Try not to move around too much as you will build up charge again. To ground yourself again, just touch the same screw or bare metal part of the chassis you touched before.

I know the PC gets power because you said you get an error code, but it may be worth at least trying some of the above.

Good luck.
 
His board is quad-channel, and should still boot fine with two sticks in there.

So I would try to boot it with one stick in the first RAM slot. If that doesn't work, try the other RAM.

Do you have the standoffs between the motherboard and case?

Yeah I wasn't sure, thought if it were quad-channel it'd be OK with the two sticks...

CJ56, I'd consult your motherboard manual and see if you have installed the sticks in the correct banks/bays, and do as claptonman said and check to see if you have installed the standoffs. Don't install more standoffs than you need, because they will short the board and give you problems, you need the right number, not too few, not too many.
