about a month ago i turned on my computer and an image of lake quill, new zealand, appeared instead of my normal logon screen. as i recall, i pressed enter, and a message box with a password entry field appeared telling me that my account needed to be re-set. i booted my computer instead, and it went away
i turned on my computer this morning and the image appeared again:

i put the computer to sleep, and when i woke it up again, my computer password entry field with my microsoft account image was superimposed over the lake. i turned the computer off, and when i re-started it this error message appeared:

i turned the computer off again, and it started normally and appears to be running normally.
what is this?
