How To Fix High CPU Usage Caused By System Interrupts

Are you experiencing sluggish performance on your computer? High CPU usage caused by system interrupts could be the culprit. System interrupts occur when hardware devices signal the CPU for attention, but excessive interrupts can lead to a significant drain on system resources. If you're tired of your computer running at a snail's pace, it's time to tackle this issue head-on and get your CPU usage back to normal.

System interrupts have been a long-standing issue for computer users. In fact, studies show that system interrupts can account for up to 60% of CPU usage, depriving other processes of the resources they need. To resolve this problem, start by updating your drivers. Outdated or incompatible drivers can cause excessive interrupts. Additionally, check for any hardware issues or conflicts, as they can also contribute to high CPU usage. By addressing these underlying causes, you can alleviate the strain on your system and enjoy improved performance.

Understanding System Interrupts and High CPU Usage

System interrupts are a vital part of the computer's operation, responsible for handling various hardware events and signals that require immediate attention from the CPU. These interrupts can include tasks like receiving input from a keyboard, transferring data between devices, or managing power states. While system interrupts are necessary for the proper functioning of the computer, sometimes they can cause high CPU usage, leading to system slowdowns and decreased performance.

When your CPU is experiencing high usage due to system interrupts, it means that the processor is spending a significant amount of time handling interrupt requests, leaving fewer resources available for executing other processes. This can result in lagging applications, unresponsive system behavior, and overall frustration.

Several factors can contribute to high CPU usage caused by system interrupts. It could be due to incompatible or outdated device drivers, malfunctioning hardware, software conflicts, or even external factors like faulty peripherals or faulty cables. In this article, we will explore various solutions to fix high CPU usage caused by system interrupts and improve your system's performance.

Identify the Cause of High CPU Usage Caused by System Interrupts

Before jumping into the solutions, it's essential to identify the underlying cause of high CPU usage caused by system interrupts. This will help you narrow down the potential solutions and address the specific issue more effectively. Here are some steps you can take to identify the cause:

• Check Task Manager: Open the Task Manager on your Windows computer and go to the "Processes" or "Details" tab. Look for processes consuming a high percentage of CPU resources. If a process called "System Interrupts" or a specific device driver is using a significant portion of the CPU, it indicates a problem.
• Update Device Drivers: Outdated or incompatible device drivers can cause conflicts with the CPU, leading to high interrupt usage. Make sure all your device drivers are up to date by visiting the manufacturer's website or using a driver updating software.
• Disconnect External Devices: Faulty peripherals or faulty cables connected to your computer can trigger excessive interrupts. Try disconnecting any external devices such as USB devices, printers, or external hard drives and observe if the CPU usage decreases.
• Run Hardware Diagnostics: Use built-in hardware diagnostic tools or third-party software to check for any hardware issues. This can help identify if a malfunctioning hardware component is causing the high interrupt usage.

By following these steps, you can gain valuable insights into the root cause of high CPU usage caused by system interrupts. This information will guide you in selecting the appropriate solutions to fix the issue.

Outdated or incompatible drivers can often cause high CPU usage due to system interrupts. Updating your system drivers can resolve compatibility issues and improve overall system performance. Here's how to update your drivers:

• Open the Device Manager by pressing the Windows key + X and selecting "Device Manager" from the menu.
• Expand the categories to find the devices with outdated drivers.
• Right-click on the device and select "Update driver."
• Choose the option to search for updated drivers automatically. If you have downloaded the latest drivers from the manufacturer's website, select the option to browse and install the driver manually.
• Follow the on-screen instructions to complete the driver update process.

Repeat these steps for each device with outdated drivers. After updating all the necessary drivers, restart your computer and check if the high CPU usage caused by system interrupts persists.

Solution 2: Disable Unused Devices

Disabling unused devices can help eliminate any potential conflicts or issues that might be causing high CPU usage due to system interrupts. Here's how to disable unused devices:

• Open the Device Manager (Windows key + X and select "Device Manager").
• Identify the devices that you do not use or currently need.
• Right-click on the device and select "Disable device."
• Click "Yes" to confirm the disabling of the device.

Repeat these steps for any other unused devices listed in the Device Manager. Disabling these devices will prevent them from generating interrupts and reduce the CPU usage caused by system interrupts.

Solution 3: Adjust Power Settings

Incorrect power settings can sometimes lead to high CPU usage caused by system interrupts. Adjusting the power settings to control the CPU's performance level can help alleviate the issue. Here's how to adjust power settings:

• Open the Control Panel on your Windows computer.
• Select "Power Options."
• Click on the power plan you are currently using to expand the options.
• Click on "Change advanced power settings."
• In the Power Options dialog box, navigate to the "Processor Power Management" section and expand it.
• Adjust the minimum and maximum processor state to a lower percentage. For example, setting both values to 80% can help reduce CPU usage.
• Click "Apply" and then "OK" to save the changes.

After adjusting the power settings, monitor your CPU usage to see if the high interrupt usage decreases. If necessary, experiment with different processor state percentages to find the optimal balance between performance and CPU usage.

Solution 4: Update BIOS

An outdated or corrupt BIOS can sometimes cause high CPU usage caused by system interrupts. Updating your computer's BIOS can help resolve any underlying compatibility issues and improve system stability. Here's how to update your BIOS:
