Dear John,

Thanks for the reply. Unfortunately, reinstalling the graphics driver
didn't help me to solve the issue. I have following driver installed,

$ rpm -qa | grep nvidia
xorg-x11-drv-nvidia-352.93-1.el7.x86_64
nvidia-uvm-kmod-352.93-3.el7.x86_64
yum-plugin-nvidia-1.0.2-1.el7.elrepo.noarch
xorg-x11-drv-nvidia-gl-352.93-1.el7.x86_64
xorg-x11-drv-nvidia-libs-352.93-1.el7.x86_64
xorg-x11-drv-nvidia-devel-352.93-1.el7.x86_64
nvidia-detect-367.27-1.el7.elrepo.x86_64
nvidia-kmod-352.93-2.el7.x86_64

Any help would be highly appreciated

Many thanks
Aneesh
