Laptop only displays a blank screen after Lenovo logo?

I have a Lenovo y50-70 laptop that won't start. I downloaded an updated for Windows 10 and then reset so the update would be applied but all I'm getting after it boots up is a black screen and I can see the mouse and nothing else. It shows the Lenovo logo and then nothing. Ctrl+alt+delete won't work and neither will any other button combos.
