When I plug the computer in the computer will turn on without even pressing power as I have previously stated, however when you press the power button to force turn off, it doesn't want to turn off. I have checked the connections for the case and they're placed correctly as stated in the Z270 manual. Another thing that happens, when you go to force turn off the LED blinks brightly four times and doesn't do anything.

I didn't find the right solution from the Internet.
