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.

 

System Interrupts using 30 - 100% CPU

Hi Bradley. I'm Greg, an Independent Advisor here to help until this is resolved.

1) See fixes for System Interrupts causing high CPU usage:

2) Update your drivers and BIOS/UEFI firmware from PC or motherboard maker's Support Downloads web page, using the full model number, Serial Number or Dell Service Tag on sticker. Compare the latest drivers available for download with the ones presently installed
in Device Manager reached by right clicking the Start button. Make sure you have the latest Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

Then type System Information in Start Search, compare the latest BIOS/UEFI firmware version with the one showing in System Information, and install it following closely the instructions on the download page, and on any Read Me file included in download.

Updating drivers from the Device Manager or Windows Update is rarely enough. The most basic thing we need to learn to maintain a PC is keep the latest manufacturer's drivers installed from their Support Downloads web page.

3) Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done:

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 17 to test a new Local Admin account. Then if necessary
continue with the other steps to go over your install most thoroughly.

4) If nothing else works then do a Repair Install, by installing Media Creation Tool, open tool and choose to Upgrade Now. This reinstalls Windows while keeping files, programs and most settings in place, is the most stable method to advance to the latest version,
and solves most problems.

I hope this helps. Based on the results you report back I may have other suggestions if necessary. If you will wait to choose whether the problem is resolved, then I will continue to help until the problem is fixed.
