Windows 10: System Interrupts 100% CPU Usage

Same problem, new clean installation is not helping and Malwarebytes is not finding anything. When I open task manager it shows System Interrupts 100% CPU Usage and then disappears. If l leave open task manager then System Interrupts does not come up. I noticed this 100% cuz my PC starts to lag a bit like input keyboard or apps slightly lag.Anyone has a solution this problem is from 2019.

100% CPU usage while on AC power - System Interrupts problem

I have been having the same issue that others have been experiencing
here, here, and here.
When you search for this you see
many results.

My symptoms:

- On battery power, computer behaves "normally".

- Immediately after plugging AC charger in, Task manager reports 100% CPU usage and never drops from that. The fan on my laptop runs constantly because of this.

The culprits in the Task Manager appear to be "System", "System Interrupts" and "Desktop Window Manager". See this screenshot:





The CPU usage of these three tasks jumps up and down between 30% and 0%, but the total CPU usage is always reported as 100%.

Steps I have taken:

1. Restart in safe mode (same issue)

2. The steps outlined in this post

3. Restart many other times.

4. Remove peripheral hardware.

I ran performance monitoring as outlined in this post. I can link the results
from a shared OneDrive folder if that would be helpful.

Here is a screenshot from that:





Where my mouse is (around 6 seconds in) is when I plugged in my laptop. There is a small spike in System (4) processes, but those go back down. When looking at task manager during this time, CPU usage is at 100%, but this performance trace does not report
the same thing as seen here:





Any help would be appreciated!!

I am running Windows 10 Version 1903 (OS Build 18362.592)

Dell XPS 15 9570 (Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz[Cores 6] [Logical/Core 2])

 

High CPU usage by "System interrupts"

I tried to solve the problem ky resetting the pc to uts pre-installed form but it didnt solve the problem. I open task manager and see 100%cpu usage by only one process. As soon as task manager opens system interrupts stops using cpu at all. When i close
the task manager the same process again stars consuming my CPU. What should i do now?

 

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.
