I have a laptop that has Windows Vista and I seem to be having problems with it. My resolution was changed by default when I installed a certain program and when I tried to change the resolution, it would freeze. The problem wasn't the program I installed, I had installed it many times before as well as on another computer. I guess the problem happened before and I only realised it then. It's not just when I open the Display Settings page, every option in the Personalize page when you right-click the Background will freeze the moment I open them. It is getting really anoying because it messes with all the resolution for my games.

Please help
