svchost.exe 100% cpu problem

Hi everyone, I'm currently helping some people to get their computer running well. The problem is that right now the task svchost.exe is taking around 100% of the cpu usage according to task manager. Anyways, I followed the instructions according to this blog post, yet the process is still taking 100% of the power. Do you guys have any other suggestions? I'm currently downloading SP3 for them but I'm running out of ideas.
 
Which SVCHost?

Run "tasklist /svc" and post which components are running in the one that's misbehaving Cross reference the PID of the svchost.exe with the on showing 100% in task manager.

From there you can either use perfmon counters for the various components (server service for example) to figure out which service in that particular host is acting up.

If you have the kung fu you can also split off the services into individual SVChosts to see which one is acting up.

 
thanks for taking a stab at this one!

yeah, I just ran that command and am having some difficulty determing exactly which one it is. I have about 10 instances of the program running right now and one of them is responsible for about 15 tasks.

In all honestly, I'm not too sure what exactly you are telling me to do in the rest of your post. I don't know how to set these counters or use kung fu. Is there an easy explanation for this?

Again, thanks a lot ofr your time!
 
just fyi, svchost.exe going into 100% is one of the bugs of norton antivirus. if you have it installed, uninstall it.

Are there any HP services running? I encountered the same problem while troubleshooting a friends computer:


svchost goes 100% with HP Solutions printer software

We'll step by step it a bit. Post the results of this and we'll go from there:
1. In task manager, add a column to the processes display that shows the process ID or PID.
2. You can then see what PID is using 100% cpu.
3. Once you have this, run the tasklist /svc and locate the svchost that has the same PID.
4. You'll then know what components are running in the svchost that is acting up. Post those here.

As an example here are two of the service hosts from my system:

svchost.exe 1384 EventSystem, fdPHost, FDResPub,
LanmanWorkstation, netprofm, nsi, SSDPSRV,
upnphost, W32Time, wcncsvc, WebClient,
WinHttpAutoProxySvc

svchost.exe 1580 CryptSvc, Dnscache, KtmRm, napagent,
NlaSvc, TapiSrv, TermService





 
we had a problem w/ this at our office on a vista machine.
i believe it had to do the print spooler and a post script driver.
