Hi,

I recently decided to build a system with a GTX 970 that has been sitting in a box for a couple of years and now doesn't start. The PC wouldn't post and beep when the PCIe power is connected to the GPU (2×6pin), however it will output image if one or both of the pcie power cables are disconnected with the warning - "please power down and connect the PCIe power cable(s) for this graphics card".

I tried two different power supplies with the same result.

Could the GPU core be dead if it still has video output for the missing power warning? Would appreciate any ideas or feedback from similar cases!
