Svchost.exe using 50% of cpu


Recommended Posts

Posted

I've seen several threads on cases where SVCHOST.EXE was using 100% of CPU.

Has anyone see it use 50% of CPU?? I have a WinXP Pro system, updated using

automatic Windows Update, running ZoneAlarm Internet Security Suite which

checks for both viruses and spyware weekly. Earlier this week I also updated

SpyBot and LavaSoft AdAware Personal, and ran both of them. I'm behind a NAT

router.

 

Yesterday I noticed that 1 of my multiple SVCHOST.EXE processes was using

50% of CPU - I'm sensitive to CPU because I run BOINC for Rosetta@home and I

expect BOINC to be using 95% of CPU.

 

It's still doing this today, and I checked it during boot before Rosetta

started, and it was using 50% CPU then when it had no competition. This is

forcing Rosetta down to 45-50% of CPU and limiting the work I can do for

them. Following a suggestion here, I downloaded and ran ProcessExplorer, but

it just says that copy is:

 

SVCHOST.EXE SVCHOST.EXE 328 50.00 Generic Host Process for Win32

Services Microsoft Corporation

 

Can somebody help here?? I'm hoping I don't have a virus.

There can be several "svchost.exe" programs running. In process

Explorer, hover your cursor over the svchost.exe that is consuming the

CPU. A pop-up window will list the services connected to that item.

Then,

start->run->services.msc

and find the service(s) listed and try to stop them one-by-one by

right-clicking on them and selecting "stop". It shouldn't take too

long to find the one using the resources.

Re: Svchost.exe using 50% of cpu

 

Pardon me while I go stick a couple of pins in my voodoo doll labeled

"Hewlett Packard." The mouse hover trick discloses that this instance is

doing just one thing: HP NETWORK DEVICES SUPPORT.

 

Key fact here: we recently bought an HP Photosmart C7280 all-in-one printer,

at least partly so we could have a networked printer. Guess it's time to go

talk to HP about why their device driver upgrade is eating my CPU. Must be a

recent change because we've had the thing for a month or so and I only

noticed this yesterday.

Re: Svchost.exe using 50% of cpu

 

Download Process Explorer.

 

For further information about Process Explorer see here:

http://www.microsoft.com/technet/sysinternals/SystemInformation/ProcessExplorer.mspx

 

It would be helpful if you could post the Command Line of the svchost

process generating the excessive CPU usage. In Process Explorer place

cursor on Process and select Properties, Image.

Hope this helps.

Re: Svchost.exe using 50% of cpu

 

Gerry,

Certainly, here is the command line call:

 

C:\WINDOWS\system32\svchost.exe -k HPService

 

And by the way, what a wonderful tool is ProcessExplorer!!
