System Interrupts High CPU Usage is a component of the Microsoft Windows Operating System that manages the communication between your computer hardware and system. It works like a system that alerts the CPU. Although it may appear like a process that is running in task manager, that is not true. This means that it is like a manager that supports CPU on a hardware level. System Interrupts signify that some hardware component is not working properly, and therefore, it has sent an interrupt to the processor.

3 Methods to Fix System Interrupts High CPU

The System hardware process mostly does not show CPU usage of more than 1% at the task manager. Although, the range may vary from 5% to 10% sometimes,  depending on the usage. Here are some quick ways to resolve the issue of abnormal CPU usage.

Method 1: Troubleshooting Devices and Drivers

Hardware detection is an important feature available in Windows 10 and other previous versions of Windows available. It is a driver software that makes it possible for your computer hardware to communicate effectively with the operating system. To fix this issue, it is important to diagnose which device or driver is causing the problem. Bad devices or drivers mostly cause these issues. Start by removing all the external devices and move to internal devices.

  1. Our goal is to lower down the CPU usage. Firstly, you should start disconnecting all the external devices like mouse, keyboard, speakers, Bluetooth devices, USB adaptor, etc. Keep on observing the CPU usage for a couple of minutes as you disconnect those devices one by one. If it doesn’t show any variation and remains the same, continue disconnecting the external devices. Still, if the CPU usage lowers down significantly, i.e., around 2-3%, it means we have found the culprit.
  2. If there is no variation in CPU usage on removing external devices, then check the internal devices and check if the problem lies there. Obviously, it is not possible to unplug internal devices like external ones. So, start disabling internal devices one by one using the device manager.

Firstly, press Windows + R and then type “devmgmt. msc” and finally, press the Enter key. You have to target devices like network adaptors, sound cards, and other add-on cards in the device manager. After you have targeted those devices, you need to disable each device and then check the CPU Usage.

If there is still no variation in CPU Usage, this clearly signifies that the device disabled is not the culprit, and you have to move on to the next one. It should be noted that some of the important system devices like disk driver, display adaptor, anything under computer, processor, or system device categories must not be disabled.

  1. After following the above steps, you should update all the devices’ device drivers because updating them will check for newly available drivers on your computer. As automatic device drivers are not reliable, we have to update them manually.

Firstly, you should right-click on the device you want to update and then click “Update Device Driver.”  After that, select the second option, which says, “Browse my computer for driver software.”

Method 2: Run Windows Check Disk

If the issue persists, check the disk for errors. A built-in Windows tool examines the disks and corrects many common errors. Try running the check disc scan using the command prompt.

Step 1: First and foremost, press Windows key + S and then search for the command prompt.

Step 2: Secondly, right-click on the “command prompt” result and select “Run as administrator” from the drop-down menu.

Step 3: You will see a pop-up screen that appears on your computer screen; click Yes.

Step 4: The command prompt window will appear on the screen. In the command prompt window, type “checks” and press Enter on your keyboard.

Step 5: Depending on the hard drive and computer power size, the disk checking process done to remove the errors may take some time. Please wait for it to finish and reboot your computer.

Method 3: Check for Viruses and Malware

Computer viruses and malware are the root cause of several problems that occur in the computer. And this issue may also be due to a virus or malware present on the computer. The viruses may cause instability in the computer system. Therefore, we need to fix the problem of “High CPU usage” by scanning for viruses and removing them.

Step 1: Firstly, press Windows key + S and then search for Windows Defender and finally, run it.

Step 2: As the Windows Defender window opens, you will see Scan’s option now. Click it.

Step 3: The scanning process can take some time. So, be patient and wait for the Windows Defender to finish checking your system for viruses and malware.

Step 4: At last, reboot your system after the scan has finished and check if the issue is fixed.

Conclusion

Many people face this issue, especially in Windows 10. Go through the above article to find the best-suited solution for your problem. They are the most effective methods to solve the issue of “System interrupts high CPU usage.” If one method does not work, then you can always try the other method. Make sure you follow all the steps carefully to attain the desired result.
