How to Troubleshoot System Interrupts High CPU Usage Problem in Windows PC

  • Computer hardware has to work hard to perform its tasks.
  • Sometimes they have to interrupt other tasks.
  • This is similar to children interrupting their parents, but getting an adult’s attention can be enjoyable or disruptive.
  • If system interruptions are taking up more than 5-10% of the CPU, we have a problem.
  • This could be due to a hardware or driver problem.

Windows System Interrupts 100 Cpu

Here’s how to fix high CPU usage caused by system interrupts and what causes them.

What Is System In Task Manager

By pressing the Ctrl + Shift + Esc keys at the same time to access the Task Manager, you are able to view what CPU, memory, disk, and network usage is causing the System Idle Process process.

What Is A System Interrupt

During Windows startup, you can find the system interrupt process in Task Manager, which displays all hardware interrupts and their CPU usage. It maintains communication between your computer’s hardware and the operating system.

High Cpu Usage By System

Hardware driver issues (bugs, old versions, incompatibilities, etc.) can often cause high CPU usage by the “System” process.

System Using High Cpu

This service hosting container consists of a bundle of system processes, including Windows Auto Update, and a number of system services. It is called a generic service hosting container. In particular, after installing a Windows 10 update, it will likely consume a lot of disk space, memory, RAM, and even network bandwidth, causing it to drain computer resources.

It’s likely that you’re dealing with a hardware issue if system interrupts are constantly eating up more than 5%-10% of your CPU.

A high CPU usage on your PC could also be caused by out-of-date drivers, malware, or even software.

You might not believe it, but computers cannot do multiple things at once. It looks like they are multitasking, but they do one thing at a time. It is hard work for your computer hardware to perform its tasks.

In the same way that children interrupt their parents by requesting attention, hardware system interruptions can be enjoyable or disrupting depending on how the interruption is handled.

What causes ‘system interrupts’ high CPU utilization?

  • An unresolved hardware or driver issue is likely to result in system interruptions requiring more than 5-10% of the CPU.
  • The processor may loop for a long period of time.

Frequently Asked Questions

  1. Unplug or disconnect all external devices.
  2. Check the hardware drivers.
  3. Disconnect internal devices.
  4. Eliminate faulty hardware.
  5. Deactivate the sound effects.
  6. Update the BIOS.

It may seem that way, but interruptions are not a bad thing. They are used to correct errors or for simple actions such as reading keystrokes or mouse movements. Typically, the system interrupt process shows less than 1% CPU usage in the Task Manager. Depending on the situation, it can range from 5 to 10%.

  1. Reboot your computer.
  2. Update drivers, check for Windows updates.
  3. Disable quick startup.
  4. Disable the Magic Bundle.
  5. Disable one hardware device at a time.
  6. Check for hardware errors.
  7. Update the BIOS.

System Process High Cpu

Right-click on this process and choose to open file location. It might be malware disguised as a Windows process if its file location isn’t a System folder.

For the past month, I’ve noticed that the process named “system interrupt” takes up a great deal of CPU power. I have looked on the internet and disabled USB Root HUBs as well as network adapters that I don’t use. Can you help me resolve this problem?
