Access denied in Nvidia control panel

Hi everyone
I have Asus laptop X450LD model and it's been a while that I have a problem with my graphic card
It doesn't let me to switch my graphic anymore and just when I click on Apply button, it says this.
"Access denied
Failed to apply selected settings to your system."
I tried to update my Nvidia graphic card but it didn't work.
Please help me if anyone could.
