Windows 10: Why when I turn on my computer it turns off after 20 seconds?

My computer keeps turning off after I turn him on, It doesn't happen before I log on my user. 20ish seconds after I turn on my computer It keeps being turned off. Can anyone assist me in any way? I tried to format my computer and it still keeps being turned off, I also tried to take out a RAM Stick and nothing works.

• Press and hold the Power Button for 30 seconds
• Connect the Power lead
• Re-insert the Battery
• Turn your System on
