According to: ftp://download.nvidia.com/XFree86/Linux-x86/ Such driver (195.27) does not exist... wasn't it a BETA driver? Some drivers may be broken for some cards - this is known fact, on both Windos and Linux, what card do you have? In any case this should be reported to Nvidia ASAP. I am using GF9100M with Nvidia driver 256.35 - everything works perfectly.
