My laptop upgraded to Windows 10 today. It is now just barely this side of bricked. This is a youtube clip I recorded the first time it went to the lock screen. After rebooting, it's now doing the same thing with the login screen.
https://www.youtube.com/watch?v=AQLE1cc5kbgI don't seem to be able to log in (surprise, surprise). I've tried holding F8 down to get a boot option list and go to safe mode on a reboot, but it's just ignoring me. I still have some limited functionality, though. If I hold down the shift key long enough, it pops up the option to enable the access features (and it doesn't flash). If I hit windows+P, I see the four options for connecting a projector pop up on the right of the screen (flashing). And I can navigate from my desktop over the network to access files on the laptop. So, the laptop seems to be alive, but it's having seizures.
Does anyone have any suggestions?
