The search bar goes to the right of screen and any subsequent search goes to right of screen

I enter search and that comes up alright and then almost immediately or even before I get the search screen the whole moves to the middle right of the screen. Google is my homepage but Google chrome works fine. Any web page which is searched for comes in to the middle right of the screen and prevents scrolling down of the web page as the right of the web page is off the screen In order to get out of search, I have to hold down the on/off button until the computer closes.
