So my PS4 is having problems...

My PS4 Pro had excellent performance before March of 2020. I bought it back in 2018 when a Black Friday sale was happening for red dead redemption 2 bundle with the pro. However after I updated my console to 7.50 back in March, everything started going down hill. It started off kind of minor. Short lags and freezes. They didn’t last long and I didn’t really care. As time went on, my console became worse. I took a break off of the PS4 for about a whole month after March because I was frustrated with it keeping on freezing. When I came back around late April/early May, it was still the same. Freezing. Crashing games. CE-34878 errors. Errors telling me my hardware failed. The console also told me to update the SAME 7.50 update multiple times even though I was up to date. And by June it got worse and worse. I got more errors saying my system was corrupted or something??? And game freeze errors. I would constantly freeze in games and they would freeze for so long to the point where I had to unplug the console from its outlet to turn it off. It froze in games and even when I loaded up the PS4 accounts. I’ve done everything. I cleaned out the PS4 (except the motherboard), initialized it twice, rebuilt database over 7 times, reinstalled the update for 7.50-7.51 over 2 times at least for each. And something has been happening recently. About 1-2 weeks now. I would turn on my console and wait for it to turn on. The logo would show up but then I would wait there for about 2-3 minutes and it would just say “no signal” on my monitor and the PS4 would shut off. Please help?? Is it my hard drive, thermal paste, or is my whole console just messed up?
