You need to rebuild the nvidia driver each time you update the kernel.
Your best solution will be to use ELRepo's kmod.

yum install elrepo-release

will set up the repository on your system. Then please see :

http://elrepo.org/tiki/kmod-nvidia

for more details. Make sure you UNinstall the Nvidia driver you have
installed before installing kmod-nvidia (the howto is on that page).
