While browsing your Task Manager window, you might have come across “System interrupts”
The Task Manager app in Windows 10 comprises a lot of processes and services that even regular users are not aware of. One such process, in Windows, that may be unknown to some users is ‘System Interrupts’.
System Interrupts is an essential part of Windows and is an aggregate placeholder that is used to display the system resources used by all the hardware interrupts present on your PC. In Windows 10, it is listed as a Windows process, but System Interrupts is just a representation to show that some hardware or software component has sent an interrupt signal to the CPU, and resources are being consumed.
Interrupts are like short messages or signals that are sent to the CPU, in case of some hardware or software related issue, that requires the immediate attention of the CPU. After receiving an interrupt, the CPU pauses its ongoing task and fulfills the requirements of the interrupt using a function called ‘Interrupt Handler’. This can be a software-related issue or some stuff related to the hardware.
As soon as the CPU receives the interrupt, the interruption handler pauses the ongoing task and attends to the requirement that caused the interrupt. Once the requirement is fulfilled, it resumes its work.
Interrupts exist to enable the hardware components of your system to inform the CPU that things like “the data you requested are now available”, or “this device would like to send data”. Any time a device or piece of software needs to inform the CPU something about the task it’s performing or needs to instruct the CPU to do something, it raises an Interrupt, which the CPU receives and handles instantly.
Generally, the System Interrupts process shows less than 1% CPU usage in the Task Manager. Depending on the situation, it can even range between 5% to 10% sometimes, but if it’s more than that, then this issue needs to be addressed.
A consistently high CPU usage typically means that a piece of hardware or its associated driver is not functioning properly.
Step 1: Restart- First, you need to restart your computer. Restarting your PC can fix a lot of weird functioning issues.
Step 2: Update- If restarting your computer does not fix the usage problem, the next step is to make sure that your computer is updated. With Windows Update, you can have all the latest Windows and driver updates. All you need to do is- make sure drivers that Windows Update does not manage, are also up to date.
Step 3: Disconnecting Hardware- System interrupts are generally caused by hardware defaulting and cause an increase in the use of system resources. If you can’t figure out which hardware is causing the issue, you need to disconnect your hardware one by one for solving this problem.
After figuring out which device is causing this issue, you can try the next steps.
Step 4: Updating Drivers- If you don’t see any hardware causing this issue, then a device driver might be misbehaving and causing System Interrupts to use high CPU resources.
You can deal with this problem by updating your device drivers.
The steps are:
Please Note: If you have recently updated a driver and any issue comes up, you will need to roll back the driver.
Step 5: Rollback Drivers-
Please Note: If you use Windows 7 and updating your drivers did not work on your system, then there may be some issue with your sound effects.
Step 6: Disable Sound Effects-
If you are on Windows 7, this is the most likely cause for the issue.
Please Note: If this does not fix the issue on your system then you may need to update your BIOS.
Step 7: Updating BIOS- Sometimes, there are bugs within the BIOS that can cause this issue in your system for which you need to update the BIOS.
Please Note: Bios updates can be tricky and dangerous for your system. Make sure that you back up your system and BIOS, just in case something goes wrong.
1. Can the System Interrupts Process be disabled?
Well, no, the System Interrupts process can’t be disabled. It is an important component for your PC’s performance since it’s used to handle and report hardware interrupts.
2. Is this process some kind of virus?
The answer is a big NO. System interrupts is an official component of Windows, hence it is not a virus. In fact, since it is not an actual process System interrupts doesn’t even have an associated. EXE or. DLL file that runs on a system which means that there is no way for it to be hijacked directly by any malware.
Basically, System Interrupts can arise from hardware or driver issues. This was all about why is the ‘System Interrupts’ process running and how to fix the system interrupts high CPU usage issues. We hope you find this article informative.
