My specs are as follows; Cooler Master HAFX case; Corsair H100i cooler; Corasir AX1200i PSU; Intel i7-6700k CPU; Asus maximus VIII Extreme motherboard; GSkill Tridentz DDR-4 3400 PC4-27200 memory; Asus Poseidon Platinum Geforce GTX980Ti-P-6GD5 GPU; Samsung SSD 850 EVO 250 GB for OS Win 10 64 bit; Samsung SSD 840 EVO 1 TB; plus other assorted SSD/HDD; Asus 16X Blu Ray Writer.
Downloaded and upgraded BIOS to 1402X64 Build Date 01/07/2016. First set the GPU in the upper slot nearest the CPU PCIEX16X8_1. On request of ASUS tech I then re-positioned down one slot to PCIEX4_2. I have never touched nor checked any switches for the PCIE slots as I don't even know where to look. I have installed Win 8.1 then upgraded to Win 10. I confirm, I only have the one GPU and no other PCIE slots are occupied. Both power cables are connected to the GPU and the white LEDs at the connection points show when the system is powered on. All drives are showing up in both the BIOS and Win 10.
Chino that's EKWB Predator 360 with 980Ti Poseidon and Maximus VIII Extreme?

Try the card in these slots...1st and 3rd...i.e x16 and x8 slot
I would try a separate PCie power cable to each PCIe power connector...not a ribbon cable that connects to both....and try some different cables your PSU comes with more than one...just in case.
Disconnect monitor from onboard graphics and connect to GPU and clear cmos.
I presume you have 24pin ATX as well as 8pin and 4pin ATX power connected? Do you have the EZ plug connected at the bottom of the board (should not really be needed...just asking)...
