I had this issue, auto is designed to only start when the GPU reaches a certain temperature. Can you post more info about your GPU? Is it manufactured by another company like ASUS but with an NVIDIA chipset? Or is it by NVIDIA themselves? In my case, I have a ASUS STRIX 1050ti, so to fix this issue, I installed ASUS GPU Tweak 2 and the ASUS STRIX drivers, as well as getting the NVIDIA drivers.
