I have a HP laptop with Windows 7 as the OS. I don't know why but since some time the right side of the display looks black. It looks like this:
And, I think if you zoom on, you can see that the taskbar at the bottom is slightly raised and below it you can see the top of the display!
Whatever I do, whatever application I open it won't occupy that black region.
I don't know how it happened. It wasn't like this before. Maybe somebody (some relative of mine perhaps) decided to try something crazy and screwed up. But here it is..
I want to know how it could''ve happened and, more importantly, how I can fix this. Suggestions?
