How To Fix ‘System Interrupts High CPU Usage’ Issue

System Interrupts are a critical part of the operating system’s function, responsible for managing hardware interrupts and facilitating communication between hardware components and the CPU. While they are essential for system operation, high CPU usage caused by System Interrupts can significantly impact system performance and responsiveness.

In this detailed guide, we’ll explore the meaning of System Interrupts, investigate the causes of high CPU usage, and provide practical solutions to resolve this issue effectively.


Deciphering System Interrupts

System Interrupts are signals sent by hardware devices to the CPU to request its attention. These interrupts notify the CPU of events such as data transmission completion, hardware errors, or user input. When an interrupt occurs, the CPU temporarily suspends its current tasks to handle the interrupt request, ensuring timely processing of critical hardware events.

Causes of System Interrupts High CPU Usage

Several factors can contribute to high CPU usage caused by System Interrupts:

  1. Hardware Issues: Malfunctioning or incompatible hardware components, such as malfunctioning drivers, faulty peripherals, or damaged hardware, can generate excessive interrupts and lead to high CPU usage.
  2. Interrupt Storms: An interrupt storm occurs when a hardware device generates an excessive number of interrupts within a short period. This can overwhelm the CPU and result in high CPU usage as it struggles to process the flood of interrupt requests.
  3. Driver Issues: Outdated, corrupted, or incompatible device drivers can mismanage hardware interrupts and cause high CPU usage. Improperly configured drivers or conflicts between device drivers can exacerbate the issue.
  4. Hardware Configurations: Certain hardware configurations, such as using incompatible or unsupported hardware components, can lead to compatibility issues and high CPU usage caused by System Interrupts.

How To Fix ‘System Interrupts High CPU Usage’ Issue

Every issue can be solved. So, in order to fix these kinds of system problems, make sure you follow the instructions carefully and make good use of the available tools.

1. USB Root Hubs 

Disabling the USB root hubs is the first step in resolving the problem. To turn off the USB root hubs, follow these instructions:

Step 1: Getting started is as simple as clicking “start” and then “run.” You’ll see a new window come up, so type devmgmt. msc and then press OK. Expanding the USB controllers is the next step.

Step 2: Then, right-click on the USB root hub and select uninstall to delete it. Restart your computer once it has been uninstalled.

As soon as you turn on your computer, Windows will immediately scan for hardware changes and reinstall any USB root hubs that you had previously removed.

2. Turn Off The Audio Enhancements

Disabling your audio improvements is a possible next step in resolving the problem. Disable audio improvements by following the instructions below:

Step 1: You begin by right-clicking on the volume icon in your Windows toolbar. The sound of a click follows. Using the playback tab, choose the current device, and then click the Properties option to access its settings.

Step 2: In the enhancement tab, select or check “disable all sound effects” in the enhancement tab. Once all corrections have been checked, click apply and then ok.

3. Turn Off The Wake on Magic Packet Settings

After deactivating the wake-on-magic packet settings, the system interruption can be fixed. Here are the ways to turn off the wake-up on magic packets:

Step 1: Go to the start menu and then to the settings. The next step is to go to the network and internet section, then click on advanced network options.

Step 2: Click on the More Network Adapters option in Step. Once you’ve selected the network adapter, right-click it and select properties. Disabled is the final option in that section.

4. Implement Intel Rapid Storage Technology 

Installing intel quick storage technology software is a second option for resolving the system disruption. Install the intel quick storage technology and accompanying software by following these instructions:

Step 1: Getting the operating system up and running is the first step. In order to use the intel rapid start technology, you must first enable it in the BIOS. A hibernation section should now be created on the SSD.

Step 2: After creating the hibernation partition, you only need to check it. Then, install Intel’s Rapid Start Technology. Your intel speedy start technology is now being tested.

5. Turning Off The “Fast Startup” Feature

In order to fix the system interruption, you can disable rapid startup as a second option. To stop the interruption, just turn off rapid startup by following the provided instructions:

Step 1: After selecting Windows, type in power options and then press enter; you’re done! Choose what the power buttons do from the left menu, and then press them.

Step 2: Afterwards, under the shutdown button, uncheck or remove the checkbox next to rapid startup.

Step 3: Finally, click the button that says “Save Changes.”

 6. Device and Driver Troubleshooting

Troubleshooting devices and drivers can also be used as an alternative way to fix the system disruption. Troubleshooting devices and drivers should resolve the issue, so follow the provided guidance.

Step 1: Identify the source of the issue with expertise and Windows Task Manager before taking any further action.

Step 2: Once the issue has been identified, use a performance monitor or process explorer to conduct a diagnosis.

Step 3: The troublesome driver can be uninstalled, reinstalled, or disabled to fix the issue.

Some Easy And Short Solutions to Fix System Interrupts High CPU Usage Easily:

Solution 1: Update Device Drivers

  1. Access Device Manager: Press Windows Key + X and select “Device Manager.”
  2. Update Drivers: Right-click on each device category, select “Update driver,” and follow the on-screen instructions to search for and install the latest drivers.

Solution 2: Check for Hardware Issues

  1. Run Hardware Diagnostics: Use built-in hardware diagnostic tools or third-party software to scan for hardware issues, such as faulty peripherals or damaged hardware components.
  2. Disconnect Peripherals: Temporarily disconnect unnecessary peripherals one by one to identify if any specific device is causing the high CPU usage.

Solution 3: Adjust Power Management Settings

  1. Access Power Options: Press Windows Key + X and select “Power Options.”
  2. Change Power Plan Settings: Select the active power plan and click on “Change plan settings.” Adjust the power management settings to optimize system performance and reduce CPU usage caused by unnecessary power-saving features.

Solution 4: Perform System Maintenance

  1. Run System File Checker: Open Command Prompt as administrator and run the command sfc /scannow to scan and repair corrupted system files.
  2. Clean Temporary Files: Use disk cleanup tools to remove temporary files and free up disk space, which can improve system performance and reduce CPU usage.
