Windows is very slow after clean install from USB

Hi Folks,

I don't know what to do. I reinstalled my system as it started to work slow after two years.

For some reason my pc feels like it is a laptop from 2000. It is taking ages to instal something, open internet site or listen to the music while doing something.

These are my specs:

Processor 13th Gen Intel(R) Core(TM) i5-13600K (3.50 GHz)

Installed RAM 32.0 GB (31.8 GB usable)

NVIDIA GeForce GTX 980 Ti

System type 64-bit operating system, x64-based processor

I have installed all drivers. Reinstalled system 3 times. Tried with updates and without. 

I have up to date bios.

I feel stuck and do not know what to do.

System repair also did not help.
