As I write this to you I do it with my head tilted on it’s side. I don’t know how I did it. I was playing video games and I guess I must have pushed a button or two I shouldn’t have then boom! My display is on it’s side. I’ve tried to restart a couple of times to no avail.
I notice when I restart the computer the regular start up in dos is right side up but when it goes to windows it’s on its side.
