ERROR: NVIDIA driver is not loaded

I need help installing the GPU on my Linux Mint machine.
I’m pretty new to Linux but trying my best.
I’ve read through many other posts and have not had much luck yet.

I ran: sudo apt-get install nvidia-driver-550.

ERROR: NVIDIA driver is not loaded

(nvidia-settings:4302): GLib-GObject-CRITICAL **: 16:21:42.663: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

** (nvidia-settings:4302): CRITICAL **: 16:21:42.664: ctk_powermode_new: assertion '(ctrl_target != NULL) && (ctrl_target->h != NULL)' failed

ERROR: nvidia-settings could not find the registry key file or the X server is
       not accessible. This file should have been installed along with this
       driver at
       /usr/share/nvidia/nvidia-application-profiles-key-documentation. The
       application profiles will continue to work, but values cannot be
       prepopulated or validated, and will not be listed in the help text.
       Please see the README for possible values and descriptions.
