svchost.exe k dcomlaunch high cpu

    Question

  • I have an HP Pavilion DV9000. Recently, we have had the system hit a high CPU. I ran and checked for Malware with different vendor products. The system is clean. The system is running Vista Business SP2. I have been an IT Engineer for 13 years. Never seen anything likes this before. I have been on the Internet where many techs of all levels have ran into the same problem, yet the solutions are band-aids at best. Reinstalling the OS is not an option as this laptop belongs to my VP of Military Sales. I have narrowed the problem down to what appears to be an issues with the svchost.exe running high with Dcomlaunch and plug and play services.

    Any help would be greatly appreciated.

  • O/S: Windows Vista Home Basic SP2

    Manufacture: Hewlett-Packard

    Model: Presario V3000 (V3411TU)

    Processor: Intel Celeron M 520@ 1.60GHZ

    Memory: 2GB

    System Type: 32 bit O/S

     

     

     “SVCHOST used high CPU resource” & way to solve this.

     

     

    **This might be one of the issues that lead to your SVCHOST problem**

     

     

    I am a vista user for 3 years now. I always update my windows for the latest update and there is no problems happen before... Until one day... suddenly my laptop is kind of slow... even watching video the video seems hang-up several times.

     

    I try to find the reason for this and when I open the (Window Task Manager), I see the oddest thing ever... my processor is working so damn hard. 1<sup>st</sup> I though the reason maybe my video that I watch might have some virus or what... but there is no virus when I scan...  I try to restart it again and the processor still working hard...

     

    Doing some research to find the reason for CPU high usage, it takes me several hour (I am a noob) to find the resource. I found out that (SVCHOST) is the reason for the processor to work harder and it related to the (DCOM Launch and Plug & Play).

     

    I flash back my previous usage of the laptop and remember that I used the (windows optional update to update some driver). I never used it before and before the problem occur I used it to update the audio driver,  graphic driver, wireless driver and some other that I don’t remember…  its about 7 optional update that I install… I think that is the source of the problem.

     

    I do some digging on the internet and found that some people disable their ENHANCEMENT at their audio setting so solved the problem… so I test it and it still would not stop… so I down grade my audio driver latter, and it solved the problem.. It goes back to normal…

     

    So for people that have this problem, you might try to down grade your audio to a latter audio if you have recently upgrade a new version.

     

    For your information, my original audio driver is:-

     

    Conexant High Definition Audio (2007 driver)    I upgrade to…

    Conexant High Definition Audio 2 (2008 driver) – I upgrade using windows update. (This is when the svchost problem happens.

     

    By downgrade back to Conexant High Definition Audio (2007 driver)... the problem no logger exists...

     

    Don’t burden you mind trying crazy suggestion, just try this... you wont lose a thing down grade you audio driver… Good luck

  • To diagnostic high CPU usage issue, you have to make a xperf trace [1]. Load the symbols to see the name of the causing function.

    If you're unsure, please upload the etl file to your SkyDrive [2] and post a link here.

    I'll take a look at it, maybe I can see more details.

  • I know this topic is a bit old but the problem seems as common as ever.  I have a solution that probably won't help many people but since it's tricky to spot I wanted to post my experience in the hopes it helps someone whose problems result from many USB device drivers.

    We use our laptops as part of a programming process for devices our company sells.  Each device has a unique serial number and as a result we end up with device drivers that are installed with each device programming but never used again.  Our laptops would slowly become unusable and digging in to the cause showed that only disabling the plug and play service would bring the CPU cycles under control.  Since disabling this service results in an unusable laptop, we did more digging and found that our problem was the unused drivers, which aren't normally viewable in the Device Manager.  To view these, you must:

    1. Right click My Computer and Select Properties
    2. Click Advanced tab
    3. Click Environment Variables
    4. Below the bottom Environment Variables window pane (System Variables), click New
    5. For Variable Name, enter devmgr_show_nonpresent_devices
    6. For Variable Value enter 1
    7. Click OK. OK to close My Computer

    Open Device Manager, click on View, select show hidden devices from the menu.  We found large numbers of unused drivers in three sections on Windows 7 machines and two sections on XP machines.  Disk Drive, Storage Volumes, and one other section.  If you see a large number of unused drivers, uninstalling them through this Windows interface is painful to say the least.  You need to click on each one and select 'unistall' after which the computer stays busy and unresponsive for a while.  The better approach is to use this free tool which allows you to view only unused drivers and uninstall all in one pass.

    (the free software is called Device Remover and is the first result if you google those two works.  I can't post a link because my account isn't verified yet)

    Be advised that you may not want to uninstall everything just because it isn't being used at that instant.  Consider what you are uninstalling first.
