I've had whole dragons appear purple. That weird unitone purple that everything is rendered in before textures are added. Skyrim will have a patch and it will appear. Then either Skyrim or NVidia will release a patch and it will go away. Cycle repeats.
If I turn down the texture setting that will correct the issue, so try that. When either the game or your graphics card releases another patch turn the texture setting back and see if the problem is fixed.
Thank you for the reply,
I have tried turning down the textures, but it was working fine from the day i bought it until few days ago, my graphics driver updated and wham, un-playable. I can send you a picture, just dont know how
