Mac won’t turn on

It looks like you may have a failing hard drive/SSD, what Mac do you have, what year is it?

Or a graphics issue

Most likely, maybe can you post a video of some sort? At the moment it is very unclear about your type of issue

Won’t turn all the way on. Will turn on the the apple updating logo load half way then shut off again.
