Question High End PC suddenly having low performance and stuttering while gaming

[Preacher_Code]

Hello, I've tried looking at possible ways to solve this issue and I don't know what to do

PC specs (slightly built off of a prebuilt I've had for over a year):
CPU: Intel i7-11700KF (came with prebuilt)
Motherboard: MSI Z590 PRO WIFI (replacement for prebuilt)
GPU: Gigabyte GeForce RTX 3070ti (came with prebuilt)
Power supply: EVGA 850 Bq (replacement for prebuilt)
Ram: T-Force Delta RGB 16Gb (2 x 8Gb) (came with prebuilt)

Recently after playing a game with a friend, the next morning I tried playing a game when the framerate dipped drastically and stayed low consistently. After a while, I shut down my pc then turned it back on and my framerate for games got better but wasn't running at the same framerate as before these issues arose, the framerate for my games dipped yet again after a few days.

What I've done so far:
Reinstalled graphics card drivers
Verified the integrity of game caches for various games
Downloaded software the amount of standby memory being used (did this the day of this post)

What are some other things I should do?
Could it be hardware issues? (I've seen people saying it could be ram)
Should I just bring it to an expert to solve the issue? (I'm contemplating because I'm tired of having pc issues as of late)

Thank you to whoever can help

Sorry I forgot to include some more info and other solutions I've tried:

Info:
The parts that I have replaced from my prebuilt were done around a month ago
I have corsair RGBs
I have MSI afterburner and the temperatures have been fine (around 40 Celcius when idle and 50 Celsius when playing a game)
I've turned off Gamebar and Capture on Windows 11

Did you ever fix or still trying?

I was able to resolve the issue, I ended up reinstalling windows and installed new motherboard drivers

Thanks for responding anyway!
