Try resit the card again. Make sure to plug in the PCIe (6 or 8 pin) power connector as well.

If your motherboard has another PCIe x16 slot, you can try installing the card there. If the card still isn't detected on both slots, there's a higher chance it's the card that's faulty.

How come you plug in a 4-pin power connector to the card? Your card should be needing 2 6-pin pcie connectors.

I've tried both pcie slots...and the gpu has a 6 and 4 pin power socket..odd but unless they've hidden the other two somewhere i guess its meant to be like that. guess i will have to return the GPU.

Some motherboards have gpu switches which controls what gpu is on or off. Try looking if your motherboard had one of those.
