What Is ‘System Interrupts’ Process And Why Is It Taking High CPU

System Interrupts are often hardware error notifications that reach the CPU. It appears to be an Operating System process, but it isn’t. System Interrupts can consume a lot of CPU, which might be problematic.

It’s important to clarify that this isn’t a virus or spyware, but rather an alarm to the processing system concerning hardware issues. System Interrupts is a part of Windows that is normally found in the System32 folder.

This article explains what System Interrupts are and how to resolve high CPU and disc use caused by System Interrupts.

System Interrupts

What Exactly Are System Interrupts?

System Interrupts is an official Windows Operating System component that serves as a bridge between hardware and the processor. If there are any problems with the system’s hardware, it sends alarms to the CPU. In the Task Manager, it shows as a process.

System Interrupts reach the CPU as a warning message if a hardware fault occurs. The CPU then stops what it was doing and focuses on the problem. It resumes its work after the job is completed and the error has been resolved.

However, the issue emerges when such disruptions occur frequently and cause your CPU to get overloaded (Central Processing Unit). System Interrupts should never be disabled or turned off. Such an action may cause irreversible damage to your system.

Hardware interrupts are an important part of any system since they allow it to run efficiently and do multiple tasks at the same time. Hundreds of programmes are operating at the same time on a computer system.

Interrupts delivers an alarm to the processor and suspends all other actions if an issue arises in the middle of the procedure. The CPU saves the progress of all actions until that moment, thus there will be no data loss.

The Culprit: System Interrupts Taking High CPU

While System Interrupts are a fundamental part of any computer system, they should operate quietly in the background.

However, there are instances where System Interrupts start consuming an unusually high amount of CPU resources, leading to performance degradation. Several factors can contribute to this issue:

1. Hardware Driver Issues:

  • Outdated or incompatible hardware drivers are a common cause of high CPU usage by System Interrupts. When drivers are not optimized, they may send excessive interrupt requests, leading to resource spikes.

2. Hardware Problems:

  • Malfunctioning hardware components, such as a faulty mouse or keyboard, can send continuous interrupt requests. These requests can overwhelm the CPU and result in high CPU usage.

3. Interrupt Sharing:

  • In some cases, multiple hardware devices may share the same interrupt request. This can lead to conflicts and increased CPU usage as the CPU must manage the shared interrupts.

4. BIOS Settings:

  • Incorrect BIOS settings or outdated BIOS firmware can affect interrupt handling and lead to high CPU usage by System Interrupts.

5. Incompatible Hardware:

  • Plugging in new hardware that is incompatible with your system can trigger high CPU usage by System Interrupts. It’s essential to ensure hardware compatibility before adding new devices.

How To Fix High CPU In Windows 10 Due To System Interrupts

Despite the fact that your device requires System Interrupts, its usual rate is less than 3%. If the rate rises to 20% or more, your computer may experience troubles. The issue could be caused by a hardware or driver malfunction.

If the issue is minor, you may be able to resolve it simply restarting your computer. Another alternative is to restart the computer and see if the System Interrupts High CPU problem reappears.

Sometimes the issue is more complicated, and you’ll notice a lot of CPU consumption. Even in such circumstances, determining which hardware is causing problems is difficult. As a result, resolving the problem may require some time and patience.

Nonetheless, there are a number of approaches to resolving the System Interrupts High CPU error. The methods for resolving System Interrupts are listed below, in order of increasing complexity:

Method 1: Device and Driver Troubleshooting

You must assume that malfunctioning drivers are to blame for the problem. Damaged drivers or devices, with the exception of a few software, are the most typical cause of System Interrupts High CPU.

If none of the above steps work, you’ll need to figure out which driver is causing the problem. It is preferable to unplug your system’s external devices first, followed by the internal components. Also, don’t forget to update each driver at the same time.

Step 1: Disconnect any external devices on your PC, including the keyboard, mouse, Bluetooth, and WiFi. Check the CPU use for a few minutes each time you disconnect a device. Continue to disconnect the devices if the user remains the same. However, if there is a significant decrease in CPU consumption (2-3%), this indicates that the device is the source of the issue.

Step 2: If you haven’t found any damaged external components, use the device manager to start disconnecting your internal devices.

Step 3: Press Windows + R and type “MSC” into the Run box, then press Enter.

Step 4: When the device manager appears, choose sound cards and network adapters one by one and disable them. To identify malfunctioning software, see if the CPU use drops by more than 20%.

Step 5: After you’ve completed the previous steps, you’ll need to update all of your system’s device drivers. Right-click on the device, choose “Update device driver,” then “Browse my computer for driver software.”

Method 2: Disable The Wake On Magic Packet

While transmitting data, Windows has a capability that allows your network adapter to wake up your computer system. “Wake on Magic Packet” is the name given to this data packet.

This data packet can cause problems because it uses a lot of CPU and sends a lot of interrupts, which can cause a lot of problems for the system. By modifying your system’s settings, you can disable Wake on Magic Packet and then enable it again if the problem persists.

Step 1: Start Run by pressing Windows + R. Type “MSC” into the dialogue box that appears and hit the Enter key.

Step 2: When the device manager opens, all of your system’s connected devices will be shown under categories; select Network Adapters from the drop-down list.

Step 3: Right-click on your WiFi device and select Properties from the menu.

Step 4: Select the Advanced option. Look through the options for “Wake on Magic Packet” and select it.

Step 5: Disable the property Wake on Magic Packet by clicking on it. Finally, save your work and exit the page. After you’ve completed this method, restart your computer to see if the problem has been resolved.

Method 3: Install Intel Rapid Storage Technology

Intel Rapid Storage Technology increases the performance and responsiveness of desktop, mobile, and server platforms that use SATA storage. It is a Windows-based application that improves system performance by lowering power consumption.

If you use many drives, you’ll be safer because data will not be lost in the event of disc failure or damage. Users have successfully used Intel Rapid Storage Technology to reduce excessive CPU utilisation in several circumstances.

As a result, installing it is a good idea, at least to see if it solves the problem. Before you install this module, keep in mind that it will change your PC’s SATA controller driver. The installation procedure is simple and may be completed in just a few steps.

You can get the module from Intel’s official website if you are confident enough to perform it without expert assistance.

Method 4: Disable Fast Startup

Fast Startup is a feature in Windows 10 that reduces the time it takes for the system to restart after it has been completely shut down. It prevents the system from shutting down normally, and it may cause compatibility issues with components that don’t support hibernation or sleep mode.

Fast Startup is similar to prior versions of Windows’ cold shutdown and hybrid sleep modes. When you shut down the computer, Windows appears to be in the same state as when it is booted up. The system logs out all users and closes all programmes in each of these situations.

Regardless, the system session will be operating and the kernel will be loaded when you turn on the device. Following that, Windows notifies drivers to prepare for hibernation, stores the current system state to hibernation, and powers down the system.

When you restart your computer, Windows does not require you to reload the kernel, drivers, or system state. It can just load the loaded picture from the hibernation file into your system’s RAM (Random Access Memory) and return you to the startup screen.

Some users have reported that their System Interrupts high CPU problem has gone away after removing this function. As a result, you can disable this functionality and see whether the problem goes away. To disable rapid startup, follow the steps below:

Step 1: To start the Run command, press Window + R. Type “Control Panel” into the dialogue box that appears and hit Enter. This will bring up the control panel for your machine.

Step 2: From the control panel, select Power Options.

Step 3: Tap “Choose what the power buttons do” on the left side of the screen.

Step 4: To enable administrator access, select the option “Change Settings that are currently unavailable.”

Step 5: Uncheck the “Turn on rapid startup” option under Shut down options. Before leaving, remember to save your modifications.

Step 6: Finally, reboot the computer to see whether the System Interrupts High CPU issue persists.

Method 5: Disabling USB Root Hub 

The USB Root Hub is a software driver, not a physical device that plugs into a USB port. You may use this software to connect a variety of USB accessories to your computer. Almost all devices include several USB Root Hubs that allow many systems to share the data channel.

Your computer’s system may be disrupted by USB hardware. If this happens, you can fix the problem by disabling USB Root Hubs in the device manager. To disable the USB root hub that your keyboard and mouse are not currently utilising, you must first determine which root hubs they are currently using.

As a result, your first step should be to identify which root hubs the external devices require, and then deactivate all other root hubs that aren’t required. The following are the steps to follow in order to complete this procedure:

Step 1: Press Windows + R to open the Run dialogue box, then type msc and press Enter.

Step 2: Expand the Universal Bus Controllers dialogue box by searching for it. Then, go through all of the root hubs that have been listed.

Step 3: Select Properties from the context menu of a root hub by right-clicking on it.

Step 4: Select the Power tab under Properties and check to see if your external components are connected. Your keyboard and mouse would appear in the list if they were using this root hub.

This root hub is used by your devices if they are mentioned under “Attached devices.” As a result, simply excluding this will deactivate all remaining root hubs.

Step 5: Next, right-click on all USB Root Hubs except the ones that are used by your keyboard and mouse. Then select Disable.

Step 6: Finally, reboot your computer to see if the problem persists. If the issue persists, it is unlikely that the USB Root Hubs are to blame. In such circumstances, you can undo all of the changes by re-enabling the root hubs.

Method 6: Disabling Audio Enhancements

Intensifiers are used by some sound drivers to improve the system’s sound quality. They use some properties that the system might not adapt to in order to improve the audio system.

As a result, the CPU may be overworked, resulting in System Interrupts. You might try turning off the sound improvements to see if the problem goes away. This isn’t the case with all sound card drivers.

Some have a different name for their Enhancements tab. As a result, it’s best to turn off all audio effects in such situations. Certain audio drivers’ “Exclusive mode” causes issues because it allows other applications to operate your sound card.

Although this may not be the cause of the problem, it is always a good idea to check to see if anything has changed.

Step 1: To start the Run command, press Windows + R.

Step 2: In the pop-up dialogue box, type Control Panel and press Enter.

Step 3: Type sound into the search bar at the top of the screen, which will take you to sound options.

Step 4: Once the sound options have been opened, select the audio device that is connected to your computer. Then right-click and select Properties from the drop-down menu.

Step 5: Go to the Enhancements tab and turn off all of the enhancements.

Step 6: Go to the Advanced tab and uncheck the Exclusive mode, which allows apps to modify audio settings.

Step 7: Finally, save your changes and exit the programme. If the System Interrupts High CPU problem persists, you can go back to step one.
