I have tried reimaging the computer, no change. When windows does start I have run all the windows and Lenovo updates, as well as turning off quick start. Sometimes it will run fine all day, sometimes it will run fine for a couple hours and then close all the programs, flash the screen, and I can't open anything so my only option is to hard shut down.

Every once in a while after resetting it 50 or so times it will start windows and everything will work fine. I have tried to start up with it unplugged and with just the external battery, just the internal battery, just plugged in and on the docking station, no change. I have reset the computer and changed the bios boot order, no impact. I have run the lenovo diagnostics (took about 10 hours) and everything passed.

When I select windows boot manager the screen refreshes. Then it will go to the boot menu (blue and gray screen with two tabs, boot menu and app menu, under boot menu my options are windows boot manager and PCI Lan, under app menu my options are Diagnostic Splash Screen and Lenovo Diagnosics). Now when I start it up I see the lenovo splash screen that says to interupt normal startup, press enter.
