New build problem, possibly mobo?

[Kyuzo]

So my new build came a few days ago, built it today and it won't work. It boots But it won't display (tested on 3 monitors), also speakers, mouse and keyboard arn't picked up by the comp. The PSU seems fine, all the led's, fans and water colling comes on, you can also hear the drives boot. I thought the reason it wouldn't display was because of the gpu, so i tested my old gtx 440 and still had the same problem. The green power light displays on the mobo, also a Red led light displays underneath the ram, couldn't find anything in the user guide about it, and there's one green (left) and one red(right) led light on the gpu. All parts were ordered from pc case gear.

parts are;

Intel core i7 2600k

Asus sabertooth p67 b3 revision

msi gtx 580 lightning

ocz agility 3 120gb ssd

corsair h70

corsair vengeance ram 3x4gb

Would highly appreciate any help,

Thanks for Reading,

If the red light underneath the ram RAM stays on then there is a problem with the RAM it should light up for a couple of secs on boot then go off. Not sure about the light on the GPU though.

EDIT: try using just two sticks of RAM both in the dark brown slots so you are running in dual channel.

yeah I was like why 3x4Gb sticks on a dual channel board sounds like ram issue to me as well if its failing ram post thats why gpu isnt going becasue with out ram posting it'll hang there. Try reseating the ram and only using 2 sticks as SieB suggested and post back to us.

Maybe you didn't put them in the right slots, my mobo only gives options for 1/2/4 sticks, I don't think 3 is an option, so take one out and put the other two in the right places (for me with 2 sticks I put in slots A2/B2)

Lol i love you =3. Took the third stick out and put the other two in the brown spots and vuala, everything works. Thanks for the help everyone =).

Will try and post some pics up of the new pc tomorrow.
