Windows 10: 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.

hey!

after using this software, my cpu usage went from idling at 80-100% and now sits comfortably at 30-45%!

 

Windows 10 100% Disk Problem on Task Manager

"However I believe 100% disk usage on task manager is not normal. "

It's definitely not normal. When your system is idle (not working on anything), the CPU usage should be 1% or less.

Now sometimes there is background work that happens -- there's thousands of things the computer does on-schedule. So sometimes it's not going to be completely idle. I explain what those things are in my post about High CPU Usage in Windows 10:
PSA: Windows 10 High CPU Usage

But outside of those things (or when those things are done working), the CPU should go back down. If not, that page will show you how to tell what background process is hogging the CPU and

 

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

 

Hi,

Downloadand install Windows Performance Toolkit (Just install Windows PerformanceToolkit, not the whole package)
Download and install the Windows ADK

Then runWindows Performance Recorder (just open Windows menu and type WPR)
