Would like to know the simplest way to reboot a PC

No it keep asking the same thing everyday after I did it just want to know if I am doing something wrong

Use the Start button and select Restart.

I did and still being asked to reboot

What happens when you click Restart?

If you want to reboot a computer
You actually want to restart it
Crashed or not.

Is the problem that it's crashed and
You wan't to get it funtional again?

I think I know your problem. There's a specific virus that does that. You should download a free antivirus program

Reboot is the process of powering off your computer and powering it back on. Because Windows maintains several files as open, if you just press the power button, you could damage these files. You should shut down through Windows by going to start and selecting Shut Down or Restart.

If something is telling you to Reboot we need to know what that something is.
