System interupts hogging one core of the processor. How can I fix this? RRS feed

  • Question

  • A week or so I noticed that system interrupts was using a significant percentage of my processor all the time. Upon googling the issue I found that it is most likely a hardware driver error. I have done a in place reinstall or upgrade of the following drivers: graphics, chipset, audio, network cards, hard drive, BIOS, and CD/DVD drive. I have also gone through Device Manager and one by one disabled devices that had the option to be disabled, except for the devices under the sub-menu system devices, in order to try to find out what device maybe causing the problem. However, nothing has worked so I am turning to the forums  for help. It seems like after restarting my computer it takes a day or so for the problem to reoccur.

    I have ran both AVG fullscan and malware-bytes full scan, in and out of safe mode.

    Thanks in advance.

  • Hi,

    Could you please explain a bit about how you noticed the issue that system interrupts was using a significant percentage of my processor all the time?

    And have you checked with Event Viewer for any errors?

    In addition, if this is related with a high CPU usage, we could use WPT to generalize a report:

    WPT: WPR/Xperf: Capture high cpu, disk i/o, file, registry, networking, Private bytes, Virtual bytes, Paged Pool/Nonpaged pool and/or application slowness.

    Best regards

  • I noticied it when I noticed that the computer was being uncharacteristically slow.

    I have not checked event viewer, I will get back to you on that one, I don't have access to the computer right now.

    I have used WPT to generate a report, but I don't know what to look for.

    Here is a view of latencyMon:

  • Hi,

    Have you checked the below thread?

    System Interrupts Huge CPU Usage

    I have checked the photo you uploaded. The above thread suggested to change the speaker configuration, which might be considered to give it a try.

    Quoted here:

    1. Right-click on the speaker icon

    2. Select playback devices

    3. Click on the speaker properties

    4. Go to the enhancements Tab

    5. Click Disable All Sound Effects

    6. Click OK. You're done!

    Best regards

  • 1. If you don't mind, could you briefly explain what part of the photo led to this? I always like to learn when possible.

    2. I cant check if that will work right now because at the moment the problem is not occurring. Previously it had seem the problem occurred about 6 hours after I had restarted the computer, and only went away after a restart. Last night the problem was occurring, however this morning it has gone away without any restart. Once the problem reoccurs I will see if this works and get back to you

    3. You had asked if I had checked any event logs. Here is a list of the only errors I could find during a time which I know the problem was occurring.   Thanks.

  • Hi,

    The photo I have checked is the one you uploaded, not saying that led to this issue, just find it similar to the thread I posted above. The picture here tells that USBport.sys is taking a high DPC, so we might give it a try to change the speaker settings.

    The event log you posted here is related with google chome update service(gupdate). For better assistance, please seek help in their offical website.

    Here is a related thread I found for reference:

    Constant gupdate in Event Viewer

    Please note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.

  • I tried disabling all speaker enhancements while system interrupts was using 100% of one core, and nothing changed, disabling speaker enhancements did not work.

  • I still have not come to a resolution on this problem. Here is a link to a Xperf/windows performance analyzer trace file if anyone can offer some assistance it would be much appreciated.
