Windows 10: High DPC caused by ndis.sys probably system interrupts Win 10

I have been playing a new multiplayer game recently which is why I never saw this problem before, and at certain times it freezes and the window becomes unresponsive. Every time I look into the task manager when this happens, I see the system interrupts process using a 100% of my CPU. Following some of the guides on the internet I found a way to diagnose this, and ran LatencyMon overnight the screenshot isn't the same analysis but same result. I don't have any problems with the audio at all by the way it may have happened only once. What should I do to fix this?

Wdf01000.sys causing DPC and audio is cracking

Is it possible that my internet provider to be causing the high DPC? Because I switched to a different provider some time around the issue started to occur? NDIS suddenly has high again. https://i.imgur.com/WNMrY4C.png

 

High DPC Latency caused by wdf01000.sys

Hello,

I am posting this regarding a problem that I ran across in my laptop at the beginning of august 2019, the problem is that I am getting high DPC Latency levels that are apparently caused by wdf01000.sys according to the latency checking
program, latencymon.

I really want to know if there is a fix since I have browsed a wide range of sites trying to find a fix, I could not find any. And also my keyboard stopped working for some reason, if its ok I would like to find a fix for that, but
I prioritize fixing the high latency over the keyboard.

Thank you for taking your time to read this.

 

"System Interrupts" process using high CPU

System interrupts appears as a Windows process in your Task Manager, but it’s not really a process. Rather, it sums up the CPU usage of all interrupts that happen on a lower system level.

Interrupts can originate from software or hardware, including the processor itself.

Wikipedia explains:

Once the interrupt handler task is completed, the processor resumes where it was interrupted.

There are two utilities you might be able to use to identify your problem
and check the DPC

DPC Latency Checker

This older utility still mostly works on Windows 10.
DPC stands for Deferred Procedure Call and is related to system interrupts.
When the interrupt handler needs to defer a lower priority task until later,
it calls DPC.

DPC Latency Checker was designed to analyze whether your system can properly
handle real-time audio or video streaming by checking the latency of
kernel-mode device drivers, but it also reveals issues.

This tool requires no installation. Launch it and let it work.
If it shows red bars, this means that you have too high DPC counts.





LatencyMon

This a latency monitor that can count DPC per driver.

To find the driver with the highest DPC count, download, install and launch
LatencyMon.
Press the Start/Play button (green arrow), wait some time, then switch to the
Drivers tab, and click twice on the DPC column to sort the driver files by
DPC count in descending order.
Drivers with a high DPC count potentially cause a high number of interruptions.

This might look like this:





Ignore the first item, which is the tool itself.
You should then examine the other high entries.
You may google for the Driver File name to find out what device it serves.
You may also disconnect such devices (if you can) to verify if they are
really the cause.

You may indicate here which drivers you have or have not managed to identify
which have a high DPC count.
You could look for drivers for these devices on the manufacturer's website.
