Why does my ps4 turn off after I turn it on?

My ps4 randomly turned off and had no reason to. I tried to get back on it on it didn't. it was checking the storage and beeped then the light turned red and shut off. I tried it the next morning and I got it to work. It was rebuilding the database and I think it finished. Right after that, the light went red and it said the overheating message and instantly turned off. I don't know whats wrong.
