Laptop touch screen stopped working. Any suggestions?

I have a Lenovo Ideapad U530. Earlier I was playing a computer game when the computer froze and an error message came up. It said something was wrong with the intel graphics driver and it would have to restart.
So it restarted and now the touch screen is completely unresponsive. In fact, according to my control panel, there's "No pen or touch input available for this display."
I'm not bad with computers but I can't seem to figure this out. There seems to not be any useful drivers or updates on the windows or lenovo sites either.

Anyone with suggestions?

Go to intel site.

You probably need to disconnect the battery to reboot it from scratch.
