Shut down after apple logo MacBook Pro

have a mid 2012 a1278 MacBook Pro 13"

its shutting down shortly after apple logo appears. Here's what I've done

I Believe I have formatted the hdd using a program In Windows. partion wizard or something i say I believe because it almost seemed as if it did not work but im

not sure.

ive changed hdd

i ran apple hardware test. It passed

i ran Apple service diagnostic test and it also passed.

NEither of the scans shut down. In fact it stayed on for hours until I forced it to shut down

Tried taking the battery out.

TRied to to boot to el Capitian usb installer but it shuts down when it tries to boot to that.

ANy other suggestions would be grand. Thank you kindly

MacBook Pro, null

The mac stays on when i try different boot functions. For example when i hold down X it will stay on and even eventually get to my log in but when i let go of the key it will shortly shut down. Also stays on when im at the screen to choose which device i want to load into. but when i click on the hdd/recovery/ or when trying to CD

So it has the ability to not shut down but how to figure out why? 😕
