How To Fix System Interrupts High CPU Usage

High CPU usage caused by “System Interrupts” can be a frustrating issue, but don’t worry, there are steps you can take to fix it. Here are some potential solutions:

Before You Begin:

Note the CPU Usage: Before diving into solutions, note the exact percentage of CPU usage “System Interrupts” is consuming. This will help gauge the severity and track progress.
Reboot: Sometimes a simple restart can clear temporary glitches.

Potential Solutions:

1. Update Drivers:

Outdated or faulty device drivers can be major culprits. Update all your drivers, especially for network adapters, USB controllers, and chipset drivers.
You can do this manually through the manufacturer’s websites or use a driver updater tool.

2. Analyze “System Interrupts” in Task Manager:

Open Task Manager (Ctrl + Shift + Esc).
Click the “Details” tab.
Right-click the “System Interrupts” process and select “Analyze wait chain.“
This might reveal the specific driver causing the issue, leading you to the right update.

3. Disable Problematic Devices:

Temporarily disconnect external devices like USB drives or printers. If the CPU usage drops, identify the problematic device and update its driver or consider replacing it.

4. Disable Fast Startup (Windows Only):

Fast Startup can sometimes cause conflicts. Try disabling it:
- Search for “Control Panel” and open it.
- Click “Hardware and Sound,” then “Power Options.”
- Click “Choose what the power buttons do.”
- Click “Change settings that are currently unavailable.”
- Uncheck “Turn on fast startup” and save changes.

5. Update BIOS:

An outdated BIOS can also cause issues. Check your motherboard manufacturer’s website for the latest BIOS version and update instructions. Caution: Updating BIOS can be risky, so proceed with caution and follow the instructions carefully.

6. Check for Malware:

Occasionally, malware can cause high CPU usage. Run a full system scan with your antivirus software.

7. Hardware Issues:

If none of the above solutions work, it’s possible there’s a hardware issue. Consider running hardware diagnostics tools provided by your system manufacturer or consulting a technician.

Additional Tips:

Monitor your CPU usage after each solution to see if the problem persists.
If you’re unsure about any step, it’s best to consult a tech-savvy friend or professional to avoid further complications.

Remember, the best solution depends on the specific cause of the issue. By following these steps systematically and paying attention to the results, you should be able to identify and fix the problem and get your system running smoothly again.
