Screen Went black graphics card problem

Right now I’m running on fail safe. I have install the NVIDIA Repository. And I ready have nvidia-gfxGO2-kmp-pae and x11-video-nvidiaGO2. I have restarted my computer. And my screen go blank or black at the login. Is there anymore think I need to install form the NVIDIA Repository (using GeForce 6100)? Is there something I forgot to do? Like a step I’m not sure of or know about? Running 11.1 kde 4.1.3

I like to see my blank or black screen problem fix.
