svchost.exe is the windows host process for system services. I have a new Dell Inspiron E1705 notebook computer (2GB RAM, Core 2 Duo Processor, internal Wi-Fi card). Two svchost processes are showing a rather odd pattern in processor useage. I set the affinity of both processes to Core1. The processor useage graph shows very regular peaks in the processor utilization of Core1. The processes seem to spike to 100% CPU for about 1 second every 10 seconds. They idle at (I'm pretty sure) less than 1%. I read on another forum that the 1 second/10 second spikes could be caused by 3rd party wifi drivers, but I can't find anything obvious. It is a new laptop after all, and I haven't installed any extra wifi drivers. Turning the card off does nothing. tasklist /SVC /FI "IMAGENAME eq svchost.exe" returns the following:
PIDs 900 and 1144 (in this instance) are the offending processes. Either of DcomLaunch and PlugPlay could be the problem; neither are stoppable for diagnostic purposes. Out of the other services, AudioEndpointBuilder, EMDMgmt, Netman, TrkWks, WdiSystemHost, Wlansvc, and WPDBusEnum were stopped to no effect. I could not stop wudfsvc. hidserv and UxSms were not stopped because they looked like they could affect the usability of the computer. Any ideas on what might be causing this odd behavior? Any possible solutions? This is only a problem because it uses 100% of my CPU. A workaround might be to write a script that identifies these processes and drops the priority to background, but I would rather not have to do that.
On my machine it was slightly different, but related.
I had lost sound and every time I re-installed the audio drivers, the sound would last until the next re-boot. Additionally, one process continually grabbed 40-60% of my dual cores (watching a usage monitor, it was all peaks and valleys). I figured I had a worm/virus but I was wrong.
After loading process explorer, I determined that the one process was using DHCP, WSCSVC and Eventlog, although there weren't entries being written to any logs) I tried shutting off all non-Microsoft services but the problem remained. So, I took a look at the Microsoft services. Two services were stopped that I expected to be running (set to disabled), Windows Audio and Windows Audio Endpoint builder. I started them up and, after a quick re-start, I noticed, in Process Manager, that Audiosrv now had joined the 3 problem services all belonging to Audiodg.exe (wasn't displayed before this). Even better my cpu usage has flatlined at about 4%.
My notebook running Windows Vista Home Premium SP1 has the same problem with svchost.exe pointing to the DComLaunch and PlugPlay services, as displayed by the process explorer. This svchost.exe uses up to 60% of my dual-core.
I couldn't stop the DComLaunch and PlugPlay services.
The problem started a few days ago when I installed the HP PhotoSmart All-In-One Printer software.
Somebody told me to disable the "Enhancement" from "Control Panel > Hardware and Sound > Manage audio devices > Speakers under Playback tab > Properties". But there is no "Enhancement" in the Speakers Properties where the controller is SoundMAX Integrated Digital HD inside the Asus A8Jr. I am already using the latest sound driver, according to Asus website.
