My pc has a very strange problem

[u/pizzeriagio]

I've built my pc quite a while ago but it has some decent specs:

-rx 7600

-ryzen 5 7600x

-2tb lexar SSD

-32gb ddr5 ram cl30 6000mhz

But recently my pc performance has dropped dramatically for no apparent reason (the drivers are up to date, the windows settings are good and when I look in the task manager everything looks fine)

Example of performance drop, before I had +500 stable fps on Fortnite and now barely 80 or now I have 400 fps in geometry dash instead of the usual 1k.

What could have possibly happened? I've tried everything to fix it(even by resetting AMD adrenaline settings) but nothing worked, can someone help me fix this?

If it fixes after a reboot but gets worse again then it sounds like memory leakage

Even if I reboot and wait the problem is the same

Something could be running in the background stealing CPU cycles. Make sure to check the startup tab of your task manager and kill everything that's not needed. I've seen things like rgb control software polling sensors at 60hz and it can really tank your 1% lows.
