I tried installing a new graphics card (gtx 1060 6gb) from intergrated graphics. After the pc not booting with the new graphics card installed I unplugged it and put the cables (believe it’s called a PCIE cable) back into the motherboard and now the motherboard lights will come on for a half a second then turn back off and nothing else will happen. Any help with a possible fix? (I’m new to PC upgrading as may be seen)
