Windows 10: System Interrupts?

Hello! I had an issue where when I changed the DNS IP in Network Adapter properties, my Windows suddenly did not respond at all for maybe 20 seconds, then it fell down to 0.1% for the System Interrupts in Task Manager! Is this normal? It seems to be normal 100% of the time now but it's still set to 0.1%, but could the DNS change cause it or do I have failing hardware?

System Interrupts - Problem or Symptom?

1 If your computer is still supported by its maker, are there any BIOS updates available? They can have significant effects on hardware.

2 Do bear in mind that the excessive** system interrupts problem might be caused by a misbehaving driver rather than an outdated driver. Checking for updates will have no effect in such cases but reinstalling existing drivers might. At the very least, I would suggest reinstalling each third-party driver just to eliminate driver faults as a cause.

3 I agree that stating your system specs could help. If other users recognise particular hardware that causes problems they might be able to suggest solutions or workarounds.

4 Do you have any particularly old hardware that might finally have been rendered fully or partially incompatible with the latest Windows updates?

5 Do have a look at the discussions I linked you to because one of them might help in isolating the cause of the problem.

6 What changes preceded the onset of the problem?

[** System interrupts are normal & they are essential. System interrupts that cause slow system performance by loading its resources are 'excessive' and it is those that my comments refer to.]

Receiving errors, System interrupts Deferred procedure calls and interrupt service routines

Hi,

Thank you for posting your query on Microsoft Community.

I appreciate if you could answer a few questions to narrow down to the issue.

• 
  What is the make and model of the computer?
  
• 
  When exactly you received this error?
  
• 
  Did you make any recent changes to the computer?
  
• 
  Which connection are you using to access internet? Wired or wireless connection?
  
• 
  Did you install any third party security application?
  

A deferred procedure call is an interrupt-handling mechanism in the Windows operating system where the drivers can reference when running certain processes. Deferred procedure call allows a task to be activated but not executed, from a highly prioritized
interrupt request level (IRQL).

As an initial troubleshooting step, I suggest you to put the computer in Safe mode and check if you receive this error.

Start your PC in safe mode in Windows 10

Let us know if you need further assistance. We will be happy to help.

Thank you.

 

System Interrupts

So I have a Asus VivoBook x541u with the following specs(initial) specs:

• Intel core i7-7500u 2.7 Ghz (boosted to 3.5 Ghz)
• 1 TB HDD
• 6 GB DDR4 RAM
• Nvidia Geforce GT 920 MX 2 GB
• Windows 10 64 bit Home Edition

Recently I have upgraded my ram from 6 GB to 12 GB and removed the optical drive in favor of an extra bootable SSD 500 GB Western Digital Drive. However, ever since the format I did my CPU runs at 30% all the time with System Interrupts. I have tried everything
since then. From checking the ram, to checking the ssd, the cpu, the drives, all the settings, everything but to no result. I also tried reinstalling windows but again no result its driving me crazy.

Memtest says I am fine, SSD bad sector tests says I am fine, driver scans say I am fine but still the system interrupt runs at 30% changing only if a much heavier application starts running, which by then runs at about 10 %- 15%. After googling I searched
all the common fixes but no result after trying them. Any suggestion would be greatly appreciated.
