How to fix System Interrupts High CPU Usage

Interrupts are a normal way for computer hardware like mouse and keyboard to communicate with the CPU in Windows Operating System. The system interrupts a process is a Windows component.

Although Interrupts are often seen running in the Task Manager, they should not cause any problems as they are running in the background.

Some Windows 10 users are experiencing CPU usage issues while the system interrupts are running. This should not be the case because interrupts only use a tiny portion of CPU resources. However, if they are causing the CPU to overload, follow the steps below to fix the issue.

Let’s get started!

Method 4: Check for Virus and Malware

Computer viruses and malware can cause instability in your computer system. Scanning for viruses and removing them can fix the problem of high usabe in the CPU.

Step 1: Press Windows key + S and search for “Windows Defender” then run it.

Step 2: Click on scan now and wait for windows defender to finish checking your system for virus and malwares.

Step 3: Reboot your computer after the scan has finished and check if the System Interrupts High CPU Usage has been fixed.

Method 5: Unplug External Devices

A common offender is USB hardware. To prevent external hardware from interrupting the CPU, disconnect all external USB devices or disable your USB Root Hub.

To disconnect external any external devices such as your USB root hubs that may be causing the CPU usage issue, open device manager by following these steps:

Step 1: Press the “Windows” and “R” keys and type in “devmgmt.msc” in the run command line and press enter or click on “OK”.

Step 2: In the list of devices, expand “Universal Serial Bus Controllers”, right-click on your USB Root Hub and click “Disable”

Step 3: Once you are able to disable USB root hubs, try to see if the system interrupts CPU usage issue persists.

Method 6: Update Your Device Drivers

Another reason why you might encounter a CPU usage issue is that you may have an outdated device driver. Getting updated driver software is important to avoid getting system interrupts process issues. Regardless of hardware drivers such, a network adapter, internal devices, playback devices, or any associated driver, all drivers should be kept updated to avoid a hardware or driver issue that can lead to hardware interrupts or system interrupts CPU usage issues.

There are 2 ways that you can update a hardware driver and other important drivers. You can either manually update them through the device manager or use third-party Windows diagnostic tools. Here are some of the steps that you can follow to update your drivers or disable internal devices.

Step 1: Press the “Windows” and “R” keys and type in “devmgmt.msc” in the run command line and press enter or click on “OK”. You may also find the device manager in Control Panel.

Step 2: Look for “Network Adapters” in the list, expand network adapters dialog, right-click on your Network Adapter and click “Update Driver”.

Step 3: Select “Search Automatically for Drivers” and follow the next prompts to completely install the new driver for your Wi-Fi adapter.

Step 4: You may also check the manufacturer’s website for the latest driver of your Wi-Fi adapter to get the latest driver. Once the update is complete. check if the System Interrupt CPU usage issue has been fixed.

If you wish to update hardware drivers aside from your network adapters, just follow the same steps above but select the appropriate device that you wish to update.

Method 7: Disable Any Failing Hardware

If a faulty driver can bring down the entire system, imagine what happens when the hardware itself fails. In that situation, updating your drivers will not help at all. To check for any faultyhardware, you can use third-party applications such as MemTest86, CrystalDiskInfo or HWiNFO.

Here’s a sample of MemTest86 detecting failing hardware:

If there is any failing hardware detected on your computer, then most likely it is the culprit that is causing high CPU usage on your computer. Prevent all hardware interrupts issues by replacing or fixing defective hardware.
