High CPU usage by Service Host & Services and Controller app RRS feed

  • Question

  • Hi All,

    My CPU is running at a consistent 98-99% within moments after booting my machine. I have uploaded a ~30s ETL capture here:

    hxxps://www.dropbox.com/s/xznhkdyo5p2p7rn/highcpu.07-03-2014.10-46-16.zip

    I've been digging around, but I can't seem to find what the cause of this high CPU usage is. It appears to be affecting the explorer service as well as Chrome. CPU usage does NOT go down if I kill all chrome processes however.

    Any insight would be wonderful.

  • Hi,

    According to your screenshot, it seems this is not related a particular service, it just like a memory leak issue.

    Can you check the event viewer to see if there is some error record?

    Or you can check if this issue happens in Clean Boot mode, this would eliminate software conflict:

  • Hi,

    From your trace, the CPU is consumed by the svchost.exe and explorer.exe, to find the real service name, we can run process explorer to check which process consumes so much CPU resource under svchost.exe:

  • Hi,

    I've looked at process explorer but Im still not sure which process is to blame. One svchost process seems to have high CPU usage while another has a large Private Bytes number (not sure if this is related) . explorer.exe doesn't seem to have anything out of the ordinary.

  • I came to this thread because I had high CPU due to  Services and Controller App. I had just added a USB header and installed it incorrectly on the motherboard. Disconnecting it solved the problem. So check your USB devices and device manager if you can get there. Disconnect USB devices to see if the problem stops.
