I received an EVGA GTX 1060 3gb today. All my other parts and fans, also LEDs etc work fine. However, when I attached my gpu and power on, nothing! The fans spin once every few seconds but there is no output! I am using an hdmi cable that is fully plugged in and that I know works fine! I followed package instructions and tried 2 different pcie ports, still the same result. And it's not my PSU either, because I am using the provided 6-pin cable and also because it successfully powers all other parts as well! Please help!
