    System interrupts 100% CPU usage


    I've been having an intermittent problem for a while now whereby Windows 10 (build 18362.418) will become completely unresponsive for about a couple of minutes. If I'm quick and launch Task Manager after it becomes responsive I can see that the System Interrupts entry is using 100% CPU. I've heard that this can be caused by buggy drivers but I have no idea how I would go about verifying that this is the case or identifying which driver is responsible. Can anyone help?

    :)

    High CPU usage by "System interrupts"

    I tried to solve the problem ky resetting the pc to uts pre-installed form but it didnt solve the problem. I open task manager and see 100%cpu usage by only one process. As soon as task manager opens system interrupts stops using cpu at all. When i close
    the task manager the same process again stars consuming my CPU. What should i do now?

    Windows 10 System Interrupts 100% CPU Usage

    After updating my graphics driver on my Lenovo computer, it started freezing after 1 to 2 minutes after booting. I was able to find out system interrupts is taking up 100% of the CPU.

    System interrupts 100% CPU usage

    atheros ar5005g causes windows 10 to have system interrupts and 100% CPU usage

    Hi,

    I have an ACER Aspire 5100-3357 originally on Vista Home Premium 32 bit. Upgraded to Windows 7 Home Premium 64 bit, then free upgrade to Windows 10. The install took 24 hours and very slow processing after and not full functionality. Task Manager showed
    high CPU usage due to system interrupts. Had BSOD. Started disabling devices and found the Atheros AR5005G wireless network adapter when disabled returned all to normal. Appears to be functioning fully except no wifi. Tried to download "Driver Detective",
    but did not solve problem. There are a bunch of sites out there claiming to have the correct driver. Tried to re-enable driver and CPU usage and system interrupts reoccurred. Tried to update driver, driver most current per windows. Have not contacted Microsoft
    Support yet. Any suggestions on getting the right driver that will not cause CPU usage and system interrupts problems?

    Thanks.

    Tim
