A little more information. I've got an ASUS Rampage IV Extreme motherboard, an Intel Core i7-4930k cpu, a Geforce 980 graphics card and 16gb of G Skill memory.
I've tried to install Windows 7 x32 on a different hard drive but even that OS doesn't seem to recognize the capture card.
Does anyone know if an additional power cable is required for the ATI Theatre 650 Pro PCIe card to be recognized? There is a place where a cable could connect on the card, but I can't find any information on the internet about it. I have used this card several years ago but I don't recall how it was connected. I used it with a different computer.
This is the exact card I have:

Does anyone know anything about this? I would think that even if the card did require additional power, it would still show up in Device Manager.
I'd really appreciate any advice you could give on this matter.
