Andrea you are in windows save mode. When you restart your computer do you get the option to start windows normally? When it first starts up in safe mode, can you got to the device manager and check on the systems icon you should see all your installed hardware. If any of them have an exclamation mark or a yellow sign check on those and best bet would be to uninstall those. I suspect you are having an issue with some hardware that windows can either not find or does not have the right driver for. Sometimes it is necessary to either reinstall Windows or repair Windows.
