I have not checked to see if elrepo has kicked out all the new drivers to fix it since then, but apparently RH changed some kernel 'pointers' in 7.3 which kind of messes up some of the kmods:

I am betting that you installed the kmod-nvidia before the upgrade to 7.3 and thus did not get the kind of warning that those folks did.
Perhaps even related to this issue:

which kmod-nvidia do you have?  At the bottom of 693, pperry indicates: "kmod-nvidia-367.57-2.el7.elrepo.x86_64 is for EL7.3".
