My Lenovo yoga 11s idea pad says connect drive. (File history drive).

My hand started twitching while on the mouse. I was in desktop properties. Then all of a sudden I couldn't connect to WiFi, half my icons were gone and it keeps telling me to connect the drive. Plus alot of error messages . Was trying to learn about the cloud , I believe.
