Windows 10: System interrupts

My system frequently just slows down completely. I have tried everything I can think of. Updates are all done. Antivirus is working. When I check the task manager, it shows system interrupts using most of the CPU etc. From time to time I get an error message in my browser, saying "a web application is slowing down your browser". It gives me the option to wait or to stop it. The only thing that works is to restart the computer. And then I just get system interrupts again a short while later. I've tried running trouble shooters, but it doesn't even give me the option to choose one. How can I figure out what the problem is?

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2 Do bear in mind that the excessive** system interrupts problem might be caused by a misbehaving driver rather than an outdated driver.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 - Problem or Symptom?

You are right, disabling the network kills the "interrupt" (don't know what to do with it though!).

Edit: this might be the answer networking - High System CPU and interrupts when network I/O - Super User (a feature that downloads and shares updates on network from my PC is enabled)
