Try setting the PCI-E slots to GEN 2 or GEN 1 in the Bios. Also make sure the PCI-E 4-pin power connectors are plugged in to the motherboard and see if Windows is installed in UEFI mode.

How to test whether Windows 10 was installed with UEFI?

I changed to gen 2 and all 4 are now appearing. It was in Auto prior.

However, the 4th GPU is coming up with Code 43 in Device Manager. I don't understand what you mean.

I just installed Windows 10 Pro via a USB from boot and installed it on my SSD.
