PS4 randomly turns off

Hi everyone , so pretty much my brother ended up dropping my PS4 (3 feet off the floor) ever since then the PS4 would just randomly shut off every time I try to start or sign in into a user . I have done safe mode and pretty much did the option where I just restarted and deleted everything and still nothing worked. I’m not sure if it’s a hard drive thing that needs to be replaced or do I have to buy a new one or so. Please help ! Thank you for your time on reading this!
