CPU in the 4090 PC is a 13900KF, it doesn't have integrated graphics. The PC which it works fine on has a 14900K which does have integrated graphics.
It doesn't matter about swapping the GPUs over because I need it working in the PC with the 20x USB ports and not the PC with the 10x USB ports.
can you disable uninstall the onboard graphics just to confirm this is the fault on the one that's working?
