Need Help With 6670

So I just put an amd radeon hd 6670 in my computer. When using the hdmi output from the card my monitor never receives an input signal, when using the mobo's hdmi, my system (bios or windows) don't find the card. There are no comparability issues as far as I know, the power supply is more than large enough for it, it's fan turns on with the system so the card is being powered by the pci(e) port, the drivers are installed and up to date, and the bios is set to use the pcie graphics.

Can anyone please help me? I can't troubleshoot this any further myself. Here's the full system:

Sapphire AMD Radeon HD 6670,
8gb G.Skill Sniper 1866MHz (2x 4gb),
MSI FM2-A85XA-G43,
Corsair CX600,
WD 1tb HDD
