why did my computer is destroyed ?

twice accidents appear on my computer that make it unable to open.

when i shutdown my computer after work.
next day when i start it , i found it could not open and i simply saw virus info on the screen.

maybe after work , i forgot to make computer do not connect internet.

after one night , the accident appeared that make it destroyed.

i think it 's very terrible for everyone !
