How to Troubleshoot System Interrupts High CPU Usage Problem in Windows PC

Believe it or not, computers can only do one thing at a time. They just do it really fast, which makes it seem like they’re multitasking. Your computer hardware has to work hard to perform its tasks. Sometimes they have to interrupt other tasks.

This is similar to children interrupting their parents. Children’s needs are also important, but getting an adult’s attention can be enjoyable or disruptive. The same is true of hardware system interruptions.

What causes ‘system interrupts’ high CPU utilization?

  • If system interruptions are taking up more than 5-10% of the CPU, we have a problem. This could be due to a hardware or driver problem.
  • Sometimes it is a huge delay for the processor to loop.
