Black Bars on my display when I updated to Windows 10

[AKESSON]

So I updated from windows 7 to windows 10.
First thing I notice is that my display has blackbars all around the screen. I have changed the resolution to 1920x1080 but it doesn't remove the blackbars from my screen. I cant update my graphic driver either, I just get an error saying that something went wrong when i try to update. Anyone knows how to solve this problem so I can enjoy Windows 10 in fullscreen mode?

My PC settings:
Intel Core i5 650 3,20Ghz
8GB RAM
Nvidia Geforce GTX 660

I changed resultion once again then rebooted my pc so now it works.
