NVIDIA drivers for CentOS 7.3

We have a HP Gen9 server with 2 Tesla M4 GPUs and CentOS installed on top of it. When the NVIDIA drivers are installed (Linux 64-bit or RHEL 7 64-bit) and rebooted, the system UI of the OS hangs.
We have uninstalled the Nouveau open source driver by blacklisting it in grub.conf and even changed the x11org.conf file to select the NVIDIA driver. Even after that its the same issue.
I even tried the EPEL repo way of installation, and still no use.
Can I get the proper NVIDIA driver for CentOS 7.3? Or is it configuration issue? We raised a support request for HP and they want us to check this from NVIDIA side.
