Windows 10: High cpu use and ticking hard drive on boot,sleep/wake cycle fixes it round 2

Hello!

The Problem:high cpu use and
some ticky tacky sounding disc access when finished booting

up-shows as follows in task manager:

Service host:diagnostic service host
Service host:diagnostic policy service
and System all run at 9 to 11% cpu each
plus:
Client server runtime process 5%
system interrupts 2%
total 40% cpu use on my I7 4790K! just doing nothing!
You can hear the CPU fan spin up about 1/2 way through booting.
My hard drive also makes a constant ticking
or galloping horse noise-it is in constant
use by 'system' 1% use

Just by putting my computer to a sleep/wake
cycle stops it and then runs normally.
The computer otherwise runs fine.
MB is a Asus Z97-P 16Gb latest bios 19??

I posted about this problem before and got help but
these instructions did not change anything:

Method 1: Perform SFC Scan and Repair Windows Image
-This process will perform scan for any corrupted system files or integrity violation and will attempt to repair it along with the Windows Image.

1. Open command prompt with administrator access
2. Type each command below and wait until scan is completed.

* sfc /scannow
* DISM /Online /Cleanup-Image /CheckHealth
* DISM /Online /Cleanup-Image /ScanHealth
* DISM /Online /Cleanup-Image /RestoreHealth

then oddly the problem stopped for a while when
I changed my ps2 mouse to usb but it came back!
the ps2 mouse was very unresponsive in the bios screen,
needing long presses of the button to sometimes register.
This ps2 mouse worked fine in windows however...

This is a real puzzler!

High CPU usage on waking up

Whenever I wake my laptop from sleep, the CPU usage seems to be tremendously high. I noticed that when Edge was launched, it took too long to respond and task manager was the only way to close it. Is there a way to fix this?

 

High CPU usage - system interrupts - when waking from sleep

I've noticed that the CPU has high usage, due to System Interrupts (ACPI.sys) running high after waking from sleep, and lately getting the BSoD when in this state and then using web browser, Outlook, or Word.

I have the latest Windows updates, have run the Power Troubleshooter
with no results, and I have done a Clean Boot with all startups and services turned off, including MS services. I still get the same high System Interrupts after waking from sleep.

Please advise.

Running Windows 10 64-bit on Asus U36SG.

 

High CPU usage - system interrupts - when waking from sleep

After reverting to an earlier Windows version and then updating the drivers again...

This did not resolve the high CPU usage after waking from sleep, and I notice that it is both System Interrupts (ACPI.sys) and System (ntoskrnl.eve) adding up to about 30% added CPU usage... and constant cooling fan running at moderate to high speed.
