GPU fans won't spin on first boot

Hi,

So this is my first desktop build, I pressed the power button, the CPU fan start, the PSU fan starts, the LED on the motherboard lights, and all seems well, until I realize my monitor is telling me that there are no signals. And then I realize the GPU fans aren't spinning. I touched the GPU with my finger, and it was warm, but didn't seem to work. All should be working, and I am hoping that it is not a defective GPU.

Specs:
CPU: AMD FX-8350 (with stock CPU Heatsink)
GPU: Radeon HD7950 (Gigabyte)
Mobo: Asus M5A99X Evo R2.0
Memory: G.Skill Ripjaws X 8GB (2x4GB)
PSU: Antec High Current Gamer Modular 750W
HDD: WD Caviar Blue 1TB.

Stupid question first, you connected the 2 six-pin connectors from your PSU to your gpu right?

I connected one 8pin connector and one 6pin connecter from my PSU to my GPU.
I'm trying to uploading some picture now.

So these are all the pictures I took. Clearly, the fans aren't spinning (The computer was "on" and the CPU heatsink fan was spinning fine as well as the PSU fan).

Looks like you have it all hooked up correctly...

If the fans don't even spin, I'm thinking defective card. See if anyone else has a suggestion/idea.

Actually, something that might be worth mentioning, is the fact that when I press the power button, the fans nudge, or budges for a slight second, and then nothing. The exact same thing when the power shuts off after holding down the power button.

Probably defective card. RMA it.

Yeah, that's what I was assuming. I thought I would make sure with you guys just to be sure.
NCIX won't be open until Monday so I'll have to wait a while before I can get my desktop working then :/

Last night, I stole my dad's six-year-old Nvidia Graphics card and put it in my PCI-E slots and tried to boot up my computer. The fans on the GPU were spinning so I'm pretty sure the PSU is not the problem, however, there was still no signal found on my monitor. I had a D-Sub cable plugged into my monitor, and used a DVI converter to plug into the Graphics Card. This really makes me wonder if there could be a problem with the motherboard as well.

Because the fans were spinning on this old Nvidia, I am now sure the PSU is fine, and the Graphics Card was defective. However, there is now a new mystery that the old graphics card did not work with my computer. Did it simply not work because it was an old piece of hardware connected to brand new pieces of hardware?
