Windows 10: System interrupts high cpu usage

Recently System interrupts have been using cpu up to 100% and I have tried a lot of what's on the web such as: checking for disk errors, get latest windows update, checking for system files corruption, updating drivers and BIOS, scanning for viruses, restoring power plan to default , disabling services that aren't Microsoft, and nothing helped So could any one please help me solve this problem.

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.

 

System Interrupt High CPU Usage

Hi,

Just realized that that the problem is in Realtek High Defenition Audio.When you disable it in Device Manager system interruptions CPU usage goes to 0.2%-1%.

Every time when I run any heavy applications like pc games,Blender 3D,etc. CPU usage goes up to 99% and the system becomes really slow.

I don't think that it supposed to be like this.

I also spot that when you delete the "Realtek Audio Driver" Windows installs some "Audio Driver" itself so could be that a Driver Conflict?

High CPU usage when idle - System and System interrupts

I've been trying to find a solution for a while and decided to ask here for more help. I've noticed that my CPU usage is pretty high when idle, even after a cold reboot of the computer:

Task Manager View showing "System" and "System interrupts" causing a high CPU load:




I've tried to dig deeper and used Processor Explorer to get more information, which, strangely enough, shows that "System interrupts" uses up more % of the CPU than the "System" process:

Process Explorer showing that "Interrupts" is taking up 20% of the CPU load:




Next I've tried to narrow down the causes of the interrupts by using the Windows Performance Recorder and analyze the graph using the Windows Performance Analyzer (can't post the screenshot due to not having enough rep, but it looks like hal.dll is causing the most interrupts, but less than the 20% seen with Process Explorer)

Any suggestions how to proceed?

Information about my computer:

• Windows 10
  
• Intel Core i5-4790k
  
• AMD R390 GPU
  
• 8 GB Ram
  

I've updated the GPU and sound drivers and Windows is up to date.
