GT710 Passthrough not working but shows up in the device manager.

[MR41211]

I am trying to get a GT 710 for a gpu passthrough to a windows 10 machine. Can someone help me with some of the issues ive had?:

1. When i start the vm, the gpu has code 43 in device manager, but if i disable, then enable it, device manager will say its working. Even though device manager says its working, it doesnt show up in task manager.

1A. When I plug in a monitor to the gpu, nothing happens

1. Code 43, which doesnt go away with disabling and enabling again

I've already tried with the latest drivers from nv and suggested drivers from the windows update, but they don't work.


I have
GT 710
Intel i5-2400
Proxmox 8.2.2
