What is System Interrupts in Windows?
System Interruptsis a part of the Windows operating system.

Instead, itrepresents the resource usage of hardware interruptshappening at a lower system level.
These interrupts are a result of processes happening at software or hardware level.
If you dont know about interrupts, let us explain to you.
Interrupts communicate between the hardware + software with your CPU.
If you switch to the mouse, the priorities of processes switch respectively.
Once dealt, the CPU resumes its previous tasks gradually.
The Interrupt process happens blazing fast, and they are almost unnoticeable.
A lot of interrupts happen at the same time.
If the CPU usage is between 0% to 3%, it is considered normal.
Sometimes, the CPU usage can go up to 7% to 10%.
This can still be considered under normalcy depending on your PC setup or the program you are running.
But Why Does System Interrupts use so much CPU?
Most probably, the problem might be related to the hardware or its driver might be working abnormally.
You dont need to panic out at this point.

Press the Start/Play button to start analyzing different drivers on your PC.
Now look for the fidrivers with highest DPC count.
Higher DPC count means the respective driver is causing highest number of interruptions.
Let the software run for at least 10 minutes to get accurate results.
