Rig built, turns on, but no signal to monitor; please help!

[tsld32]

Hi everyone, I just got my parts yesterday and put everything together, but I go to turn it on and the monitor isn't getting a signal.

The GPU has both HDMI and DVI and I've tried both; neither get a signal. GPU is powered (fan runs).

When I turn on the comp I hear a couple beeps, and the fans all work (including the one plugged into the cpu-fan pins, so I assume that means the mobo is getting powered).

Memory is plugged into slots 2 and 4 (as per the mobo manual instructions). Tried putting them in 1 and 3, no change.

Optical and SSD plugged into SATA2's (changed SSD from SATA3, no change). Optical seems to read things, but nothing displays.

The lone jumper is on 1-2, which looks correct (2-3 is CMOS clear).


Here are my parts:

CPU: AMD Phenom II X4 965 Black 3.4GHz Quad-Core Processor
Cooler: Cooler Master Hyper 212 Plus 76.8 CFM Sleeve Bearing CPU Cooler
Mobo: ASRock 970DE3/U3S3 ATX AM3+ Motherboard
Memory: G.Skill Ares Series 8GB (2 x 4GB) DDR3-1866 Memory
Storage: Mushkin Chronos 120GB 2.5" SSD
GPU: Sapphire Radeon HD 6850 1GB Video Card
Case: Cooler Master HAF 912 ATX Mid Tower Case
PSU: Antec Basiq Plus 550W 80 PLUS Certified ATX12V Power Supply
Optical: Sony AD-7280S-0B DVD/CD Writer

Any help is appreciated. Would it help if I uploaded a picture? I'm not sure how revealing it will be but it can't hurt.

Here are some photos I took of the inside, complete with my feeble annotations

Again, I'd appreciate any suggestions you guys have.

Thank you

Okay, never mind, I figured it out. Forgot to plug in the 8-pin cpu power. Ugh -- how embarrassing. I thought they were talking about a different plug-in.
