I downloaded My NVIDIA update and i found this error :

I reinstalled it agin but same error/problem
Given that your screen shot doesn't much information, I take it that either you've downloaded the wrong drivers, or you've already got the latest version. Assuming you've got the right drivers (otherwise, go get the right ones), try doing a clean install by uninstalling your display drivers and NVIDIA control panel completely, then running the installation.
