Ps4 shutting down, doesn’t download or update

Starting at the beginning of this year, my ps4 started shutting down on me randomly. I cleaned it out, moved it to an area with better ventilation and now when I try to download new games it always says that it’s corrupted, and when I try to update it it always fails. (SU-37559-9) is the code it gave me most recently for the failed update. When this started I had recently rearranged, but I always make sure to properly turn the ps4 off when I rearrange to avoid messing with anything, maybe I did something wrong this time? Is there anyone who might know how to fix this that can help me, of if you need more details of what’s happening I can give some.

For example, when I play games the screen suddenly turns black and freezes for a bit, before I can continue. Sometimes it will fully freeze up and I just have to hold the on/off button on the ps4 to get it to work again.

I miss playing my games and having a working ps4, if anyone can help me I’d appreciate it :)
