The system interrupt process is one of the Windows operating systems most common processes, but what exactly does it do? System interrupts are used by Windows to perform low-level tasks such as disk access. The result of high CPU usage caused by system interrupts can be sluggish performance or even a Blue Screen Of Death (BSOD). Here’s how to fix them and get back your computer life.
System interrupts are a process that is used to handle various system events. When this process becomes high, it can cause a lot of CPU usage and other issues. This article will explain the difference between “System Interrupts” and “High CPU Usage Caused by System Interrupts.” Read more in detail here: what is the difference between.
You may have seen “System Interrupts” in your Task Manager on Windows 10 before or now. Unless you saw it with 100% CPU use, you probably disregarded it. But if you’re wondering what System Interrupts are and why they require so much CPU, we’ve got you covered. This article will also teach you how to resolve the excessive CPU consumption that System Interrupts produce.
In Windows, what are “System Interrupts”?
The Windows operating system has a feature called “System Interrupts.” It’s shown as a process in Task Manager, but it’s not what it seems to be. Rather, it denotes the resource consumption of hardware interrupts at a lower system level. These interruptions occur as a consequence of software or hardware activities.
Let us clarify interrupts to you if you are unfamiliar with them. Interrupts are used to communicate between your CPU and the hardware and software. If you use your mouse, for example, the hardware and motherboard can simply manage it rather than dedicating an entire process to it. When you move to the mouse, the priority of the processes change. If the hardware’s priorities are high, the CPU devotes the whole process to dealing with the interrupt. Once handled, the CPU gradually resumes its prior responsibilities.
The Interrupt process is lightning rapid and practically imperceptible. Several interruptions occur at the same moment. You may check your “System Interrupts” use by opening Task Manager and scrolling down in the Processes tab until System Interrupts appears. It is considered typical if the CPU utilization is between 0% and 3%. The CPU use might spike to as high as 7% to 10% at times. Depending on your PC configuration or the software you’re using, this might still be deemed normal.
But why do System Interrupts use so much processing power?
If the CPU use of “System Interrupts” is continuously over 20%, it’s a warning that your computer is acting strangely. Most likely, the issue is caused by faulty hardware or a driver that isn’t operating properly.
You don’t have to be concerned at this stage. The first and most important step in recovering your PC from excessive CPU utilization is to restart it. We know you’ve heard that a thousand times, but it really works the majority of the time. If that doesn’t solve your issue, we have a few additional options for you to try.
How Do I Fix High CPU Usage Caused By System Interrupts?
If restarting your computer doesn’t solve the issue, try one of these solutions to get rid of your high CPU utilization caused by System Interrupts.

1. Make sure Windows is up to date.
This issue could be resolved by updating your Windows to the most recent version. Windows updates also contain the most recent driver updates. If the excessive CPU utilization was caused by a driver failure, the problem is likely to be resolved. This won’t update all of the drivers, but it will update the ones that the Windows operating system manages.
To do so, go to the “Updates and Security” section of the Settings program on your Windows PC. If there are any updates available, click “Check for updates” and download them. After you’ve finished, you may want to restart your computer to ensure that the updates take effect. This setting may be able to alleviate the excessive CPU utilization.
2. Unplug or disable external devices
If the drivers aren’t the issue, another option is that an external device is malfunctioning. If you’re still noticing excessive CPU consumption, unplugging all of your external devices might be one of the best remedies. If it doesn’t solve the issue, then deactivate external devices using the methods below.
- Hit Enter after clicking Start and typing “Device Manager.”
- Locate the Universal Serial Bus Controllers entry in the Device Manager and double-click it to expand it.
- Under the expansion, disable each USB Root hub one by one. Make careful to do it one at a time and avoid disabling the USB Root hubs on the mouse and keyboard.
Also, if any SATA wires are hanging out while hooked into the motherboard, be sure to disconnect them.
3. Check For Hardware Issues With DPC Latency Checker
If the preceding two methods didn’t address excessive CPU consumption caused by System Interrupts, you may wish to check into driver problems. You may use the DPC Latency Checker tool to do so. DPC stands for Deferred Procedure Call, which is utilized by interrupt handlers to postpone low-priority tasks.
DPC Latency Checker measures kernel-mode device driver latency to determine if your PC can support real-time audio and video streaming. The program needs no further installation and displays driver faults in real time.
There’s something wrong if the DPC Latency Checker shows some high peaks. It demonstrates that a driver’s latency is high. You may either restore your Windows PC to its original state by resetting it, or you can do a full reset.
You may also use LatencyMon to find out which drivers have the greatest DPC count. To begin examining various drivers on your PC, use the Start/Play button. Find the fidrivers with the highest DPC count. A higher DPC count indicates that the driver is producing the most disruptions. To acquire reliable results, run the program for at least 10 minutes.
4. Disconnect the plugs from the internal devices.
Rather of focusing on external devices, it’s advisable to deactivate all of them one by one, including internal ones. It’s recommended to turn off internal drivers for any devices you suspect are the source of the problem. Follow these instructions to do so.
- Hit Enter after clicking Start and typing “Device Manager.”
- Start deactivating the drivers one by one after the Device Manager has opened. Make cautious to go gently and avoid turning off the display adapters, keyboard, or mouse, since this may cause your PC to act strangely.
Keep an eye on the System Interrupts in Task Manager while you’re deactivating the devices. You may also run the DPC Latency Checker again to double-check your decision. Once you’ve determined that the device isn’t the problem, you may re-enable it by right-clicking and selecting Enable.
Always keep in mind not to deactivate system drivers, which may be found under Computer, Processor, and System Devices.
5. Make a BIOS update
The BIOS is the first thing to load when you turn on your computer. Examine your PC’s BIOS version and the BIOS on your manufacturer’s website. It’s time to upgrade your BIOS if they don’t match. Follow these methods to determine your BIOS version.
- Press Enter on your keyboard after clicking Start and typing Command Prompt.
- In Command Prompt, copy and paste the following command and press Enter. wmic bios obtain manufacturer, smbiosbiosversion | systeminfo | findstr /I /c:bios2
- Command Prompt will show the BIOS version after it has finished running.
Before upgrading the BIOS on your computer, make a backup of your data. You may need to hurry to a service facility if the BIOS causes system failure.
6. Turn off the sound effects
If your PC runs Windows 7, you should attempt to turn off the sound effects. This is how you do it.
- In the system tray, right-click the speaker icon.
- Double-click on your Default Device under Playback Devices (Speakers).
- A Properties window will appear as a result of this. Go to the Enhancements tab now.
- Turn off all sound effects. To confirm, click OK.

Most Commonly Asked Questions
Is it possible to turn off System Interrupts?
No, it’s not possible to turn off “System Interrupts,” and there’s no need to do so. It’s a crucial part of Windows, and if you attempt to turn it off, your PC’s performance will suffer. If you’re wondering, Windows won’t allow you terminate the job either.
Is it possible that System Interrupts is a virus?
Technically, System Interrupts isn’t a virus. It’s a built-in feature of the Windows operating system. As a result, it is not a virus. It can’t be accessed by any virus since it doesn’t identify itself with any EXE or DLL file types.
However, there’s a chance that a virus is interfering with your driver, resulting in excessive CPU utilization and System Interrupts. It is recommended that you check your computer with your selected anti-virus software.
