New Build - No Signal from graphics card. Onboard video works

[seans9]

Gigabyte GA-Z68X-UD3H-B3
Intel Core i5-2500K
Corsair Vengeance 8GB (2 x 4GB) DDR3-1600 Memory
Sapphire Radeon HD 5770 1GB Video Card

This is a brand new build (my first). Everything works great except for the graphics card. I'm able to boot into my OS (Hackintosh 10.6.8) with the onboard video working, but when I plug my display into the DVI port on the graphics card I get "No Signal". Even when I turn the computer on with the display plugged into the DVI port (either port) I get "No Signal" but it still posts.

- I tried both DVI inputs with no luck
- Double checked everything is connected properly (I even assembled it outside of the case)

Not sure if this is relevant or not, but I had to get a new PSU because it wasn't working. When that came in I realized the motherboard wasn't working...what are the chances that the video card is also messed up? Any ideas?

Check your bios settings for the video order

should look something like

PCIE Graphics -> Onboard GPU
or
PCIE -> PCI -> Intergrated.

check you have the aux power plugged into the card.

did you take the propper antistatic measures to ensure you didnt fry every piece u picked up?

Are there drivers for the 6770 in OSX?

I checked that and changed the setting for "Onboard VGA" from Auto to Enable If No Ext PEG. I also changed the setting for "Init Display First" to PCIEx16 (tried PCI and PCIEx8 too) with no luck.

Yes

Yes

Also, I forgot to mention that the card's blue LED light is on so I know it's getting power.
