No Signal from GPU

So, a couple of weeks ago, I finished building my new computer. I made sure all of the internal stuff was plugged in and seated correctly, plugged everything into the back of the tower and turned it on and my monitor got no signal. I've tried every socket (DVI, HDMI, DisplayPort) and the same thing happens for all of them. It's really driving me up the wall.

The graphics card is a Gigabyte GV-N660OC-2GD and the motherboard is a Gigabyte GA-X79-UD3, which doesn't have on-board graphics.

I have done a bit of research already, but the only solutions I've found have been for people who are replacing or upgrading their GPU and already have an OS installed, but I haven't been able to get that far, since I can't see anything on the screen.

Any help would be really appreciated. Thanks.

Right. I wasn't sure if I'd need the rest of the specs, but here they are:
Intel i7-3820 processor
32GB DDR3 RAM
240GB SSD
3TB HDD
Creative Sound Blaster Recon3D Fatal1ty Champion sound card
D-Link DFE-530TX PCI-Bus network card
Antec EA-650-Platinum PSU
Pioneer BDR-207DBK optical drive
(I think that's everything needed, I don't list specs very often, so let me know if I've missed anything)

I have checked several times that the GPU is seated correctly, I've taken it out, made sure the socket it was in was clean, reinserted it and made sure that the latch on the socket clicked when I pressed the card in. The fans on the card work, so it should be getting power. It had better not be dead, since I haven't actually gotten a chance to use it. I will admit, though, that, since this is my first full build, I'm not too familiar with troubleshooting, so I'm not entirely sure how to test if it's dead.

If it beeped or I had a debug display, I'd be able to figure it out myself. Unfortunately, however, I have neither.

So, I was playing around with my computer today. I was trying to test the graphics card in our other desktop, but it wouldn't fit because the case is too small. I also tested the tiny little graphics card from that in my computer, but the same problem happened, so could it be that the problem isn't being caused by the graphics card. I'm not familiar with the way BIOS generally works, but maybe the BIOS thinks the motherboard has on-board graphics, even though it doesn't, and is causing conflict as a result? (Do correct me if I'm wrong, since I probably am.)

Never mind, it's all sorted. I was searching for solutions on another forum and found instructions on how to fix my problem. It turns out the computer was being temperamental about having more than 16GB of RAM. I'm not sure what would have caused it, but I took two sticks out and it works fine.
