Is my HDD the reason my PC got slow?

My pc really got slow some months ago just like that. And I am trying to narrow the reason down.

I have downloaded CrystalDisk to try and have information about the disk. But I don’t even know what info it is giving me. So I come here to ask you if you know if any info of the following could tell if the disk is the reason for the slowness or not.

I have also reinstalled windows on the disk and the problems continue.
