High CPU and High Physical Memory usage. RRS feed

  • Question

  •          

    I have looked all over many forums and haven't found a solution.

    Lately I have noticed that when I open any application that my CPU usage skyrockets from 30-40% to 98-100% percentage. And Physical memory usage gets pretty high. I went and looked and found that there was a really high percentage of non-paged pool and found that it was being used by a svchost.exe the services associated with it are Application Infomation and Application Experience. I have tried restarting App Exp and it didn't affect anything noticable. Is there a safe way to restart App Info and whould it make a difference. If anyone else has had this or a similar issue please respond cause I have no idea what to do and this is almost making my computer unusable. Also I run both Super antispyware and WEbroot and I only came up with a few advert spyware and webroot has come up empty for the last month. Please help.

  • You're looking for things you don't need in Autoruns. Essentially all windows needs to boot are some disk drivers... so your Intel/via/nvidia/sis/amd storage drivers must load everything else is optional but it may affect sound and screen resolution.

    Disable the other stuff and then reboot, iteratively enabling more things until you find the issue.

  • Hi,

    Try to use process explorer to narrow down the culprit.

    Process Explorer v16.02

    http://technet.microsoft.com/en-in/sysinternals/bb896653.aspx

    In addition, we could perform a Clean Boot to test if it could caused by the third party software or service.

  • 1. Performance Monitor, Process Explorer, Autoruns and Process Monitor are your friends in this case.

    2. Make sure that programs that you are running, namely AV, do not interfere.

  • Yes but what am I looking for and how do I fix what I find?

  • Like Milos says.

    Autoruns (http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx) is your first step. Start disabling services, unneeded drivers and startups.

    Once you identify the culprit for the high usage (you may need Process Explorer), get ProcMon to see why. It could be something simple like a driver infinitely checking for a missing registry entry or missing file.

    RAMMap can also help you properly identify the source: http://technet.microsoft.com/en-us/sysinternals/ff700229.aspx
