Topic: PS4 won't work

yesterday i was tired of my PS4 freezing all of the time. I couldn't even play anything cause of how slow my Ps4 was acting. But when i tried most of the options in "safe mode" it made everything worse.
is there something I can do

It's a bit over a year and a half old.
i haven't tried checking the hard drive tho.
I also thought it might be do dust build up.

and it's a slim

ok so i've spent the past few days looking stuff up and experimenting
i don't believe the problem is my ps4 overheating
i'm lead to believe it's either my hard drive or something on my motherboard.
Cause it'll turn on and sometimes stay on for a while
then it'll either freeze or stuff will stop downloading then it'll shut itself off.
