Windows 10: Computer won’t turn on but power source has been checked

My Dell computer won’t turn start. The power source for computer, monitor, mouse and keyboard have all been checked. I saw others advise doing Windows Logo + R to run a command, but my system is not responding to anything and screen is black. Any suggestions to force the turn on?

Asus Transformer t100ta won´t turn on Win10

Yesterday was reading on it. All of a sudden turned off and now it won´t turn on

 

I unplugged my computer to soon and now it won´t start up again?

Thanks for your answer.

This solution did not solve my problem since my computer won´t power up at all. it is as if the computer is completely dead and I have tried different outlets that work for other computers but it still won´t power up.

Is my motherboard broken?
