Firstly, check if your windows detects a part without a driver by going into device manager. because the gpu takes up a pci lane, it should recognize something there.
The drivers are provided by Nvidia and not by MSI. It's just a generic geforce driver that can be found here https://www.geforce.com/drivers. if this doesn't work, comment below and we can figure something else out.
GPUs are generally soldered onto the mobo so it may just be a driver issue.
