System CPU usage too high RRS feed

  • Question

  • Hi, i've been trying to troubleshoot this problem for some months.. everytime i try to use perfmon or another program to watch for network usage (download and upload) the System process spikes to 13%~ constantly until i close it.. I could "live" without that but now everytime i'm using an application on my second monitor, the same thing happens... started happening just an hour ago, and it's really bothering me because i don't have a clue what driver could possibly cause this.

    I've tried capturing xperf traces on another forum but they keep come as corrupted as the person whose trying to troubleshoot with me tells me, and i can't seem to get a grip of the xperf analyser myself to see what (driver?) is using the cpu so i can try to replace it...

    Anyway, as i type this it jumped up to 20% and i don't know what to do.

    I'll upload two xperf traces here, but at least one is "corrupted" as the other kind member on the other forums told me. (which is the first one below)

    https://dl.dropboxusercontent.com/u/36066558/highCPUUsage.7z

    https://dl.dropboxusercontent.com/u/36066558/highCPUUsage2.7z

    And the one i just recorded, https://dl.dropboxusercontent.com/u/36066558/highCPUUsage3.7z

    Does someone have another way or can help me find what's causing it?

    I used the command xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 512 -FileMode Circular && timeout -1 && xperf -d highCPUUsage.etl

    I took a print of the System process Threads in Process Explorer http://i.imgur.com/vbW36rU.png

    Before the today's change, the function shown there was mostly ntoskml.exe!KeGetCurrentProcessorNumberEx+0x34, i don't know if that means anything...

    Thanks.

    First Xperf has been replaced by Windows performance recorder.  Second there was almost no data recorded in your trace.  Please run a windows performance trace as instructed in the wiki and upload it.  Make sure you run the trace when the problem is happening

    In order to diagnose your problem we need to run Windows performance toolkit the instructions for which can be found in this wiki

    If you have any questions feel free to ask

    Please run the trace when you are experiencing the problem
