New build does not work. Taking all suggestions!

by Ortraf / November 12, 2013 5:58 AM PST

Hello everyone,
I recently *tried* to upgrade my machine and I have run into a problem (SPEC BELOW). Whenever I turn on the power, the CPU fans and the GPU fans run but there is no display on screen or any USB connection (mouse/keyboard). Also, after a while my computer shuts itself off.
I've tried to run it with a single stick of RAM in different locations (different sticks in different locations) but it still wont run.
I have everything connected (PSU to GPU, HSK, and 8 pin/ 24 pin connections to Mobo) as well as RAM firmly connected.
I did notice that the Motherboard flashes FF code (which doesn't appear in the manual). I've searched online and found an online manual which states that the FF code means "power on and initialize CPU". Does this mean I connected something wrong regarding the CPU/Mobo/HSK? I should mention that I have had the mobo stored in the original wrap for months and only now got the time to install it.
Also, I should note that I did not format the hard drive that I was using before. I don't think this would cause a problem with the computer not POSTing, but you guys would probably know more about that.
I'll go test the PSU by swapping it out for a known good one, but I think it has to do more with my Mobo or CPU. Anyways, I want to know your guys opinions or solutions.

Computer Specs:
Motherboard- MSI 890fxa gd70
Cooler- Corsair H80
PSU: XION AXP-850K14XE Quad 12V, 850W
CPU: Phenom II X6 1090t
GPU: AMD HD 7850 (Single)
RAM: Samsung PC3 10600/ DDR 1333/ 3 2GB sticks + 1 4GB stick

Let's say this is a new board.

Many come with a little piece of paper to remove on the cmos battery. Also, besides that, no HDD is needed or ODD or much else.

We don't need a case either. Keep removing things we don't need to beep or display.

Just for drill have you tried removing the 4GB stick to see if it would run with the 3 2's?
