System Interrupt is a vital process in your operating system that manages hardware-related issues like drivers, clocks, and memory controllers. However, sometimes, System Interrupt can run high, causing your system to slow down, freeze or even crash. This high CPU usage results from certain glitches within the operating system, hardware issues, or outdated drivers. If you are experiencing such issues, this article will guide you on how to fix high CPU usage caused by System Interrupt.

1. Identify the cause of high CPU usage.

Before you can start fixing high CPU usage caused by System Interrupt, it is essential to understand the root cause of the issue. To do this, you need to follow these steps:
a) Open the Task Manager by pressing Ctrl + Shift + Esc or by right-clicking on the taskbar and selecting Task Manager.

b) Go to the Performance tab and click on Resource Monitor.

c) Under Resource Monitor, click on the CPU tab to see the processes taking up the most CPU.

d) Look for “System Interrupts” to see how much CPU it’s using. If it’s using more than 10%, then take note of it as this is what’s causing the high CPU usage.

2. Update your drivers.

Outdated drivers can cause System Interrupt to run high and lead to high CPU usage. To prevent this, regularly update your computer’s drivers to the latest version. You can do this by:

a) Pressing the Windows key + X and selecting Device Manager.

b) On the Device Manager window, right-click on the device you want to update and click Update Driver.

c) Select “Search automatically for updated driver software” and wait for the computer to search for new drivers.

d) If there is an updated driver available, then install it.

3. Disable certain devices.

If updating your drivers didn’t fix the high CPU usage, the issue could be due to a faulty device. To find out which

device is causing the problem and disable it, follow these steps:

a) Press the Windows key + R to open the Run box and type “devmgmt.msc” to open the Device Manager.

b) Expand the section for each of the devices listed and right-click each one individually.

c) Select Properties from the dropdown menu and go to the Driver tab.

d) Click on Disable Device to temporarily disable the device.

e) Monitor the CPU usage to see if disabling the device helped.

4. Adjust your processor’s power management settings.

Your computer’s power management settings can also cause System Interrupt to run high, leading to high CPU

usage. To adjust your processor’s power management settings and prevent this, follow the steps below:

a) Open the Control Panel, then click on Power Options.

b) Under the power plan you are using, click on Change plan settings.

c) Click on Change advanced power settings.

d) Under Processor power management, set both the Minimum processor state and Maximum processor state to 100%.

5. Clean your computer registry.

The registry contains all the settings and configurations of your computer’s hardware and software. If there are corrupted files in the registry, it can cause System Interrupt to run high, leading to high CPU usage. To clean your computer registry, follow the steps below:

a) Download a reliable registry cleaning software like CCleaner.

b) Install and run CCleaner, then click on the Registry tab.

c) Click on Scan for Issues to let CCleaner scan for any issues in the registry.

d) Click on Fix Selected Issues to resolve any registry problems found.
