Hi! Misty
Restar the computer and hit the '''((F8))''' in your keyboard when the computer boot-up. Then when the menu screen appears choose '''Service mode with the up and down arrows and hit Enter''' and wait for the system to finish boot-up. When the system finish search and uninstall the program causing the problem and restar your computer. But if this not working make a test connecting a external monitor if this work maybe your laptop graphics card is bad or your screen is dead and you need computer service.
