PC does not start ...

It started fine in the morning but doesn't work.

The afternoon class was canceled due to the student's convenience and I had free time until the evening class, so I thought I could prepare for next week's study session and festival event ...

For some reason, it does not start with a black screen.
It's a long time, but the outside is awesome!
And when you look at the mountains, it is pure white. I guess it's snowstorm.

I didn't want to go outside, so I switched my mind and started to sort out the shelves.

A4 size papers are piled up on the shelves like a pile, and I thought I had to do something.

This is also a place you can not easily access if you do not have the time, so I think that it was good that the computer did not start now, but I am horrified if I do not start it as it is
