I recently bought a core x to run with my Lenovo Yoga 730 15in, and the first day I plugged it in everything went great. I installed the thunderbolt 3 drivers and it was recognized by the system, so I order a gpu and a week goes by. I got my card, an RX 580, and all of a sudden when I plug my core x in, it says Thunderbolt functionality may be limited. I tried without the gpu and got the same error. I reinstalled thunderbolt drivers and power cycled my core x, but I get the same issue. The core x's fans turn on and work but my graphics card is not working and the fans dont spin. Any solutions?
