Question PC underperforming

[Schieblade]

Hello,
I dont even know where to start.

This PC always underperformed a bit for no good reason.
Since some weeks that underperforming increased quite a lot.
I am now getting around 170 fps in Games like League of Legends or Destiny 2 even less.
I cant get any further with my knowledge so I am asking where to start....

Btw the Installation of Win11 is quite fresh and I already did a DDU and so on

I really hope someone is able to help find a solution.

Thank yall in advance

Specs:
OS: Win 11 (Ver 10.0.22000 Build 22000)
Mobo: Z370 AORUS Ultra Gaming
Cpu: I9-9900k
Graphics Card: Rtx 3080 MSI Gaming X Trio
Ram; 3600 Mhz 2x8 gb

Welcome to the forums, newcomer!

We're going to need a little more information. When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list them like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:

What BIOS version are you currently on for your motherboard? Where did you source the installer for your OS? Include the age of the PSU apart from it's make and model. Lastly, how are you cooling that processor?

If it helps I think my CPU is getting a little hotter than normal. But not that much like 7 C° but still noticeable.
