I have run into this issue and it happens after the first reboot after Windows 10 updates the Video drivers. The issue is an old BIOS. I let the issue happen on 3 of my machines. After the issue occured, I booted up the BIOS install disk I had, updated the BIOS and it resolved the issue. I had 10 other E550 laptops that I updated the BIOS before it installed the video drivers and the issue never occured. I am 13 for 13, so update the BIOS for the win.
