How to Fix System Interrupts High CPU Usage in Windows PC 2022

Computer systems are susceptible to various hardware malfunctions, including CPU spikes. These spikes are often caused by system interrupts. This is because the CPU must process every request that comes it’s way.

It does not have any way of knowing which requests are urgent or less important. The result is that the CPU spends most of its time responding to low-priority interrupts, instead of the high-priority ones that actually need attention.

The good news is, there are fixes for this problem! This article will show you how to fix high CPU usage caused by system interrupts, and get your PC back up and running smoothly without having to spend a lot of money on upgrades or repairs.

What is system interrupts?

System interrupts are an official component that is part of the Windows operating system. It controls the communications between your hardware and your system. It is displayed as a running process in the Task Manager. It’s used to display the system interrupts high CPU usage of all hardware interrupts.

How to Resolve System Interrupts High CPU Usage

If your system is constantly interrupted and consumes up to 5 to 10 percent of your system, then something is not right and you’re likely experiencing an issue with your hardware. We’ll assist you in getting to the root of the issue.

The first thing to try is restarting your computer. If that doesn’t work, begin with this guide:

1. Unplug all external devices.

As we mentioned earlier, the system interrupts high CPU usage, which can be caused by driver or hardware problems. We suggest that you disconnect all external devices individually while Task Manager is running and show the CPU utilization of system interrupts.

Remove external devices and peripherals such as the keyboard, mouse, microphone, webcam, etc. One by one, and see whether you can see if the system interrupts the process behaves normally. If normal behavior is restored when you unplug a particular external device, you’ll determine which device is the culprit. The issue.

2. Restart Your PC

The first step is to start your Windows 10 computer. No kidding! A complete reboot will resolve a myriad of odd problems. So, make sure you test it out first, as it’s simple enough to try.

3. Turn off all sound effects

If you play audio or video files, the system interrupts CPU usage will also increase. Turn off sound enhancement in order to fix the issue.

1.) Right-click the sound icon in the taskbar to select “Playback devices.”

2.) Double-click on the playback device. Choose to open the Enhancements tab to turn off any enhancements.

Select OK to save the settings.

4. Update the Drivers

Because the CPU interruption issue is typically hardware-related, you should try updating the drivers. It’s a straightforward and simple procedure that usually works. It’s also important to ensure that drivers are always up to date.

  1. Click the button to start.
  2. Start typing device and then choose “Device Manager.”
  3. Expand each component until you reach certain devices. Right-click, and select Update Driver.
  4. Choose Search automatically for updated driver software. You may also Browse my computer for driver software. You know where to find it.
  5. If it detects an appropriate driver, then install it. It is also possible to search for updated drivers in Windows Update.
  6. On Windows Update, select Check for updates, even if it says that you’re up-to-date. This might surprise you.

5. Check your disk for errors.

If updating your operating system can reduce the CPU use caused by system interrupts, examine the disk for issues (it is always recommended to check disks regularly for any errors).

The built-in Windows tool is a way to check the integrity of disks; it analyzes them and corrects the most common errors. This tool can be run via the command line or via a graphic interface. This article explains how you can run it using the Command Prompt (running it from the command line).

To launch Command Prompt, type “command prompt” and right-click on the “Command Prompt” result. Choose “Run in administrator mode” from the drop-down menu.

Enter “chkdsk C: /f” command in the Command Prompt window and hit enter on the keyboard. Change the letter “C” with the number of your hard drive, even if it’s not the C drive you’d like to check (or your Windows operating system itself is located on another drive).

This “chkdsk C:”/f” command detects and fixes logical problems that affect your drive. To repair physical issues, also run the “chkdsk C” /r” command.

It is possible to run both commands simultaneously by entering “chkdsk C/f /r” (Windows will need to restart your computer in order for the process to be completed). The process of checking the disk will take some time according to the computer’s power and the size of the drive.

Be patient and wait until the process is completed. Note: If you get an error message that states that Chkdsk cannot be executed due to the fact that it is currently in use by another process, then you’ll be asked if you would prefer to plan the volume for a review at the next time your system starts up.

Hit the “Y” key on your keyboard. It will then be inspected for any errors that occur after the restart.

6. Hardware Disable and Enable

If you are not able to delete them, then you may also opt to remove the hardware from your Device Manager. This is applicable to hardware that is internal as well.

  • Open Device Manager
  • Find the device that you wish to deactivate.
  • Right-click and select the option to disable the device.

Be sure to turn off each device separately. Give the device a couple of minutes and observe if there is an increase in CPU utilization to identify the hardware. If there’s no change, then enable the device that you turned off, and then shift onto the next device. If you observe an improvement, you’ll be able to pinpoint the cause of the system interrupts high CPU usage in Windows.

Here’s a bit of advice: don’t disable any drives essential to keeping your system running.

7. Rollback Hardware Drivers

If an update to the driver has caused this issue, it is possible to restore the driver to the previous version. It is possible to check Windows Update History to identify the latest updates. It’s possible that the latest driver isn’t addressing a problem that has been reported that isn’t compatible with the latest versions of Windows.

8. Disable USB Root Hubs

System interrupts high CPU usage can also be because of a USB hardware issue. The solution is to turn off USB Root Hubs in Device Manager to correct the issue.

Open Device Manager.

Expand and search for Universal Serial Bus controllers dialog.

Right-click on every USB Root Hub except the ones that are for your mouse and keyboard.

Choose “Disable device.”

Right-click on the USB Root Hub to choose Properties.

You can then check the attached devices in the power pane.

After deactivating your USB Root Hubs, check whether your system interrupts high CPU is fixed.

9. Turn off internal devices

Instead of randomly updating drivers, start with disabling individual drivers on your device to determine the cause. If you’ve already identified the culprits, you can remove them first.

Open the Start menu, type in, and then open Device Manager.

Expand the devices listed below. Right-click on a device and choose Disable.

Perform this procedure for just one gadget at a time and then check if the system interrupts high CPU usage is fixed.

These devices are most likely to be the cause:

  • Internal audio devices
  • Network adapters
  • Internal modems
  • Any additional cards, such as TV tuner cards, ISDN and DSL adapters, or modems?

If none of them are to blame, then you can begin by disabling (and enabling) other drivers that aren’t essential.

Don’t disable any driver you require to operate your systems, such as everything listed under Computer, Processors, and System device.

Don’t also try disabling the display adapters as well as the disk drive that powers the system you’re using, IDE controllers, your mouse or keyboard (unless you have an alternative input device like an electronic touchpad), or your display.

10. Update BIOS

A BIOS (Basic Input Output System) is a piece of software that is stored on a memory chip that is located on the motherboard. It is possible that you will need access to the BIOS to alter the way that the device functions or for help in resolving the issue. The update of the BIOS may help you solve the issue if you are unable to discover the root of it.

The device that is responsible for interrupts could have issues, and so updating BIOS may fix the problem. Be aware that changing the BIOS is an option for experienced users, and in the event of improper execution, could result in permanent damage to the hardware.

To upgrade the BIOS, visit the official website of the motherboard manufacturer and download the most current BIOS version for your motherboard. There should be a guide explaining how to update your BIOS. Make sure you carefully read the instructions. If you don’t know how to update your BIOS, consult a professional to ensure that you do not damage your system.

Are system interruptions caused by viruses?

System interrupts aren’t an infection. The system interrupts is an authorized Windows component. You can view it as a Windows procedure in the Task Manager which will report the CPU utilization of all interruptions to your PC. System interrupts are essential to ensure that hardware and software with the CPU.


System interrupts are a common cause of high CPU usage, and this can happen for various reasons. Your system may be faulty or there might be a conflict with the hardware, operating system, or other software. This post will go over some solutions to help you fix high CPU usage caused by system interrupts.
