resolution problem

Hello, I have a problem with my resolution setting , it changes every time I shut down the pc. I have it set to1360x768 but when I turn my pc on it will be anything but the above . The only way I can get it to go back is by going in to my controls, reset the res and then say no to the change it will then go back to my setting. Below is what I am running. Any help with this would be great, thanks.
