Hi. I just built a hole new system with an MSI B85-G41 motherboard and an Intel i5-4670k processor and bought this videocard to go with it. I already tried to see if my old videocard would work and be detected, and it does. When this new one is plugged in with both power connectors and everything, the motherboards will not detect that anything is even in the slot. I've tried it on both my PCI-E slots and neither of them detect anything plugged in. I'm starting to guess that the card might be a dud but would like to see if anyone has any idea about what could be wrong. Thanks in advance for any help.
