Check your bios settings for the video order
should look something like
PCIE Graphics -> Onboard GPU
PCIE -> PCI -> Intergrated.
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.
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?
