Constant 100% Disk Usage, 60-80% CPU usage. Both happen when idle.

So on Saturday of last week my PC started to run slow. I open up task manager to check what was going on and I am greeted with it showing me that I have very high CPU usage, and constant capped-out disk usage.
Over the course of the past few days I have reinstalled Windows 10, updated drivers, completely formatted my previous hard-drive, and just today I received a new SSD. However, my problem STILL persists, and I'm all out of ideas on what I need to in order to solve this.

My Motherboard is an ASUS Z97-P with an Intel i5-4690K processor. If you need more specifications, or a program to be run, then I would be happy to do so.

For further information, the system ran normally when booting from a Windows 8.1 hard-drive, and did have a blip of normal performance on Windows 10, but resumed misbehaving when the computer was re-started.

in Task Manager sort by CPU usage and see what apps are responsible.

The processes using the most CPU and Disk are shown here.

Could you also provide a snapshot of Resource Monitor with selected Disk Activity Tab and checked only System:

i would also suggest running checkdisk and sfc /scannow
