My Lenovo ideapad 100s shows a blank screen on the desktop? How can I fix it?

I was on Facebook watching a video and the screen turned black all of the sudden and I thought the battery ran out so I plugged in the charger and tried to turn it on with the the power button but only the white screen shows up and I can't acces anything and I can turn off it with the powe button either please someone help

Hold down the power button to force a shutdown. Then restart, if the white screen happens again when you start it up, take it to a tech, you have a hardware problem
