  Can you see all the 4 cards in the device manager or GPUZ. If not, you need to connect A1B17 of the PCIE slot. Just search PCIE card presence pin.

  Buy a USB riser and use that for the PCI 1x card.

  I had problems with my 1x to 16x risers. Ended up having to purchase 16x to 16x risers. Unfortunately, the riser problem is mother board specific and you won't know until you test it with both types. This issue has to do with the lack of specification of how the PCI channel should be implemented on the MB. Different manufacturers choose different designs, leading to some MFG have compatibility with 1x to 16x risers and some only have compatibility with 16x to 16x risers.
  
  I recommend a 16x to 16x riser that comes with an external MOLEX power connector, in addition to a capacitor to clean the power (example from Alibaba)
