If you see it in the BIOS then it is not an operating system artifact.
It sounds like the screen is gone - perhaps not refreshing itself. I
have seen not unsimilar before (caused by external power spike? -

Do you think this could cause Linux to spontaneously lower screen res
and change refresh rate from 60 to 61 Hz?
