Question PC automatically shuts down after one minute ?

[EdselLopez]

When i turned on my pc pc today it booted up and then automatically shutdown after a minute. I then switched off my psu, turned it back on and then same thing happened.
Now my pc isn't even turning off, and when i press the power button the cpu moves a little but doesn't spin and then stops ?

Need help!
