I need some help here. I have a Zotac GTX 670 4gb and when I set it into the PCI-e slot, and plug in both the six pin connectors, I get no signal from my monitor. I have put the card in both of my mobo's PCI-e slots. I have reseated the card many times. I also have an MSI GTX 670 Power Edition which works just fine on my board. Not to mention with the Zotac, the fans are going at 100%, so it basically sounds like a hair dryer in my pc. Any suggestions before I just go ahead and RMA it?
