Can you post your config file or command line?

Squiggly letters, written really fast, with a couple of dots for good measure.

Did you setup the OS with one GPU and add the 3 later? or did you have all 4 GPUs plugged into the motherboard and install the OS?

For me I used to setup the rig with one card, then move it to my mining shelf and hook up the other 3 GPUs.  I used to have your problem all the time.  Sometimes I'd get 4 cards, sometimes 3, sometimes 2.

Now I just hook them all 4 GPUs from the beginning and install the OS.  Never had a missing GPU in device manager this way.
