And youll find it as a process in the Task Manager.
But, the finding wont be pleasant if you see the System interrupts alone consuming the entire CPU power.
Why is it causing high CPU usage & how to fix that?
If youre seeking the answer to both, you must read this article till the end.
So, lets begin!
What is the System Interrupts Process?
System interrupts is a communication medium between the hardware and the OS.
Its like a signal that alerts the CPU only when any hardware task requires high priority.
After accomplishing the task, the CPU returns to the previous on-hold instructions.
You might face system interrupts using7%to9%CPU or even 10%.
But, what makes the system interrupt 100% of CPU usage?
What Causes System Interrupts to Use 100% of the CPU?
Additionally, corrupted rig drivers trigger this issue too.
However, any failing hardware in the PC will cause the CPU utilization to be 100% constant.
It handles mostly hardware-related processes in the system.
Thats why anything wrong with the hardware will affect CPU usage by a significant margin.
And this hardware task handler will represent that.
Let me show you the fixes real quick.
Windows Installer Moduler Worker engages and causes high CPU usagewhen Windows installs new programs.
Its a quick and fast fix.
Plus, update all outdated hardware drivers and look for any faulty hardware.
Replace the damaged hardware if you find any plus, updating the BIOS will patch this up too.
Windows OS built-in sound effects or enhancements make this process consume more CPU power.
Thats why disabling all the sound enhancement will reduce CPU usage and solve the problem.
Now, lets move into how to fix System Interrupts that cause 100% CPU usage.
Here are the methods to fix system interrupts causing high CPU usage:
1.
Disable USB Root Hubs
Faulty devices cause trouble in the system when you connect one to the PC.
As a result, youll face the system interrupt process consuming 100% of the CPU power.
To know the mouse and keyboard is connected to which USB, simply right-select theUSB Root Huband chooseProperties.
Go to thePowertab and check the attached devices.
Youll find the mouse and keyboard are in the list if connected.
After disabling the USB Root Hub, restart the PC and check the system interrupt CPU usage.
I bet youll find the system interrupts CPU usage is normal now.
Sometimes thesvchost process can increase CPU usage.
If thats happening to your PC, read our troubleshooting guide and fix it in an instant.
Update Hardware Drivers
Outdated hardware drivers are another reason behind system interrupts 100% CPU usage problem.
To patch this up, check for backdated hardware drivers and update those as early as possible.
After the download is complete, Windows will roll out the latest driver automatically.
Repeat the same procedure to update other rig drivers too.
Restart the PC if required.
If the backdated drivers are the real culprit, updating those already solved the issue.
Updating the Windows will update the unit drivers too.
you’re free to also read our separate guide on how toupdate drivers on Windows 11.
We have listed all the possible ways you’re able to do that.
To do so, follow the below steps.
If not, then the web link adapter is the main culprit.
Otherwise, switch on the data pipe adapter again and disable other internal devices too.
Then verify if the issue exists.
If you are not getting the desiredInternet speeds on Windows 10, check our separate article.
There we have written an extensive guide on the troubleshooting steps.
So, look for any damaged hardware in the system.
Like a faulty hard drive, the RAM could get damaged too.
you’re free to use someprograms to check for faulty RAM.
Faulty RAM increases CPU usage by system interrupts.
So, change the RAM to solve this issue.
System interrupts might max out the CPU utilization when the sound enhancement is enabled.
Disabling it will solve the problem for sure.
So, follow underneath steps to do that.
Here are the steps to disable sound effects:
Now, restart the PC.
After a restart, you wont find CPU utilization maxed out by the system interrupts anymore.
Windows 11 comes with many changes and optimization.
You wont find the old sound prefs in Win 11, as you find them easily in Windows 10.
That is where our guide comes in.
Turn Off Fast Startup
Is Fast Startup feature good or bad?
Some find their PC performance improves after they enable fast startup.
But according to my test, disabling the Windows fast startup solves the system interrupts high CPU usage problem.
To turn off Windows fast startup, simply follow the steps.
You have fixed the 100% CPU usage issue by the system interrupting process.
Update BIOS
If the above methods didnt solve the problem, then its time to sneak into the BIOS.
Because backdated BIOS could trigger the system interrupts process to consume massive CPU power.
For this, you must check the BIOS version and update it.
Executing this command line will show you the current BIOS version of the system.
Now, go to the manufacturers website and look for the latest BIOS version.
If the systems current BIOS is outdated, download the latest one.
Then follow the manufacturers instructions to update the BIOS.
Note:Updating the BIOS is a very complicated & risky process.
So, take expert help if needed.
This hardware task manager process isnt the only factor that can make CPU utilization high.
But dont worry its possible to fix high CPU usage by applying some methods no matter what causes it.
FAQs
Is system interrupts a virus?
No, System interrupts isnt a virus.
Its a process that helps to maintain communication between the hardware and the OS.
Can I end System interrupts task?
Thats why you cant disable this process.
How can I fix System interrupts using high CPU?
Moreover, disabling the corrupted internal devices also fixes the high CPU usage by this hardware task prioritize process.
Wrapping Up
System interrupts help to speed up top-priority hardware-level instructions to be executed first.
But, this process shouldnt exceed CPU usage of more than 10%.
In this article, I have shown the main reasons behind this issue and the solving methods.
I believe you read till the end and already solved the issue.
