You may do the same with Windows resource manager to get deeper insight. Is there a consistent way to determine what EXACTLY is causing the system interrupts? Lots of posts in lots of places just say "update your drivers" but never what drivers, and seriously? Corrupt device drivers often lead to a very high DPC latency, which can also cause Systems Interrupts.

If high CPU load is the issue then you might try first Windows task manager, eventually followed by its Windows resource monitor. If you sort that display on CPU load, you should get an idea which process is taking most of CPU load if the load isn’t distributed over a couple of processes.

  • Swapping is the act of running each whole process in main memory for a time then placing back onto disk and vice versa.
  • When the hardware accelerator is known, the analysis tends to focus on how best to drive it, trying different variants of drivers within the complete system context.
  • There might be various system interrupts causing high CPU usage.
  • It is used when the system does not have enough main memory to hold all the currently active processes.
  • If a process dies and the parent exits without detecting the child’s death via a wait call, that child process is inherited by init.

Use Device Manager to disable some USB root hubs to check whether the issue has been resolved. Press CTRL + ALT + ESC to start Windows Task Manager and end processes not needed under Processes tab. "System interrupts" isn’t really a process, even though it appears in the "Details" tab lists of processes.

You could run the DPC Latency Checker to confirm whether the driver issues are culprits. If there are corrupted device drivers, you need to repair them and download and install correct drivers, such as chipset drivers. It is well-known that USB devices can result in System Interrupts and high CPU usage.

Task Manager just displays it that way to give it a label. In case you find red bars that indicate drop-outs due to high latency, then there are some troubles. To resolve it, update your drivers with the standard version or access control over the driver updates and block future updates.

High interrupts means some hardware is either faulty or the driver is flakey. Yes, automatic update of drivers by Windows is better to disable.
