On a healthy system, system interrupts will hover between 0.1% and 2% of CPU usage, depending on the CPU frequency, running software, and attached hardware. Intel Rapid Storage Technology improves the level of performance and responsiveness for devices using SATA disks for desktop, mobile, and server platforms. It is an application based on Windows OS and enhances the performance of the system by reducing power usage.
- Once this region is reserved, the hardware is informed of its location and incoming data will be written to RAM where it will later be picked up and processed by the networking subsystem.
- Monitoring this file can help you determine if the interrupt coalescing settings you select are actually working.
- In this mode, the processor can execute privileged instructions that define interrupt vectors, enable or disable system interrupts, interact with I/O ports, set timers and manipulate memory mappings.
- Further, using interrupt coalescing will also affect the statistics gathered from this file.
- In order to do this, the device driver must work with the OS to reserve a region of memory that the NIC hardware can use.
If you are using multiple disks, it keeps you on the safer side, as there will not be data loss during disk damages and failures. USB hardware can cause system interruptions in your computer. If such a case happens, you can disable USB Root Hubs from the device manager to resolve the issue.
Also, identify the programs that are associated with that service and if it is bloatware or unwanted program that you don’t use then uninstall them. However, if it is a system process or service then try to identify the real cause for them to consume your CPU because in normal cases, they don’t cause high CPU usage continuously. It provides you with multiple checks for your hardware, software, CPU, network, disk, and memory softwire free download , along with a long list of detailed statistics. You can see the Windows process in your Task Manager which reports the CPU usage of all interrupts happened to your PC. System interrupts is important for the communication between software and hardware with the CPU.
Some sound drivers use enhancement to improve your sound quality. If these properties are incompatible with your computer, some problems such as system interrupts high CPU usage. In this case, disabling Audio Enhancement may help you fix the issue. The network adapter has the privilege to wake up your computer when transmitting data, which may cause high CPU usage as a lot of interrupts are generated during the process. So to stop system interrupts high CPU, you can disable the feature.
To disable the USB root hubs that your keyboard and mouse are not using currently, you have to find out which root hubs they are using. Therefore, your initial step is to find the root hubs the external devices need and then deactivate all the other root hubs. The USB Root Hub is a software driver and not the hardware that you plug into a USB port.

Drivers are programs that control particular devices connected to your motherboard. Updating your drivers may eliminate compatibility issues or bugs that cause increased CPU usage. Do this for one device at a time, check the CPU usage of system interrupts or re-run DPC Latency Checker, then right-click the device and select Enable before moving on to the next device.
As the computer runs, processing switches between user processes and the operating system as hardware and software interrupts are received. If a process is still using too much CPU, try updating your drivers.
To quickly check whether you’re dealing with a driver issue, you can run the DPC Latency Checker. Deferred Procedure Call is a process related to system interrupts. When the interrupt handler needs to defer a lower priority task until later, it calls on the DPC. Interrupts can also tell the CPU that an error occurred and this can cause a spike in the CPU usage of system interrupts.

This software allows you to connect numerous USB peripherals to your system. Almost all devices have numerous USB Root Hubs that help you share the data bus with multiple systems. Even though your device needs System Interrupts, its normal rate is below 3%. If the rate hikes up to 20% or above that, it can cause problems to your PC. If the problem is not a major one, you might be able to solve it by rebooting your system.
