Hello! I just purchased the GT 610. I installed it into my brand new computer, and it won't register at all. I am running Windows 7 64-bit, with an ASRock z75 Pro 3 Motherboard. I try to install the drivers, but it says there is no hardware recognized. I tried to find it under the device manager, but it isn't there at all. I tried physically removing the card, and reinstalling it, and no luck. I tried to install it in a different slot, and my computer wouldn't start at all. Is there something else I can do, or did I get a dud?
