If you are installing Nvidia's binary video drivers for linux. You may run into a problem with the installer complaining about differing versions of gcc on your machine and what version the kernel was compiled with. The following should get you past that hurdle
1. First extract the files from the .run file Nvidia offers from here.
[daniel@linuxone][daniel]# sh NVIDIA-Linux-x86-1.0-5356-pkg1.run --extract-only
2. go into the extracted directory and install the drivers
[daniel@linuxone][daniel]# cd NVIDIA-Linux-x86-1.0-5336-pkg1
[daniel@linuxone][NVIDIA-Linux-x86-1.0-5336-pkg1]# make install CC=gcc32
The drivers should install without a hitch.
