About two years ago I built a computer with the AMD A8-3870K APU. I'm now trying to install a discrete graphics card to use the dual graphics feature the APUs have.

I installed a Gigabyte ATI 6670 in the PCI Express slot and have tried connecting it via both HDMI and VGA, but there is no video output. If the graphics card is installed, the motherboard VGA doesn't output any video either. I have installed the card in another computer and it booted fine there, so it isn't DOA. I don't think it is a problem with the power supply output either as the power draw of the 6670 is roughly 65W. I have a 450W PS in right now, but I installed a 500W and got the same result. This graphics card does not require a direct line to the power supply.

Current Build:
MSI A75MA-P35 FM1 AMD A75
AMD A8-3870K APU
Rosewill Stallion 450W PS

Adding:
Gigabyte ATI 6670 GPU

Yeah, it's in there good.
The fan spins, and all the lights and other system fans come on as well, but there's no video. Usually if there's a video problem the system will beep a certain code to indicate that video cannot be output, but it isn't doing that either.

I'll check out the bios version, but I just updated it a few months ago.

I'm not sure what you mean by the pci power connector. This graphics card does not require a direct line from the PS if you are talking about the 6-pin connector that usually runs to a graphics card. I have the 24-pin connector and another 4-pin connector that run from the PS to the MB.
