Windows 10: System Interrupts at 100%

Recently I've noticed lagging while using my laptop. Mostly while light gaming (It's an Intel iGPU so really light gaming)

The CPU is i5-4200m with Intel HD Graphics 4600
While I am gaming or using the laptop, I feel it suddenly stuttering / lagging
I open Task Manager and see System Interrupts at 100%, but for a very brief moment and then it disappears

What could it be?

Thanks

System Interrupt 100%

Hi Team,

Off late my system briefly hangs or stops responding randomly - I have Acer Aspire laptop purchased 3 months ago with Core i5 1035G1 10th generation with Windows 10. On a couple of occasions; I was able to access task manager and it reflected "system interrupt"
under processes tab marked in Red with value of 100%.

The problem appeared after I encountered BSOD once and following news on the internet, uninstalled cumulative update KB566782. Since the uninstall, I've not encountered BSOD issue again but then noticed this new issue of "system interrupt @100%" which previously
did not occur.

The only other change my system has gone through; is updating system drivers via "Intel Driver Support Assistant". Following is the history of update:

1. Roughly 3 weeks ago - Intel UHD Graphics driver update and Intel Wireless Bluetooth (21.110.0.3)

2. On 16Sep2020 - Intel UHD Graphics driver (27.20.100.8681) and Intel WiFi Driver (21.120.2.1)

Please suggest what can be done to fix "system interrupt" issue.

Thanks in advance

System Interrupts frequently at 100%

Hello, my computer will be functioning normally but at random times everything will lag out and the computer will become sluggish and when I open task manager I will be greeted by system interrupts at 100%. I have searched on the internet for this and have
never seen people asking about system interrupts being 100%. All my drivers are up to date and functioning properly, and I don't seem to have a problem with my hardware. If you need anymore information about my computer just ask. If you have any suggestions
or ideas on how to solve this issue please reply.

Many thanks

 

How to fix system interrupts 100%

Thanks for help
- The task manager does not always show system interrupts 100%, only when my laptop is running slowly.
- I open command prompt and type the code (copy & paste) and nothing happens
