100% cpu utilization

P

priyank

hey guys,

I've been having trouble with my dell 700m laptop running windows xp
sp2. After using the Internet my cpu levels go up to 100% and stay
there while i surf. If i stay on one page (ie read an article) they
drop, but peak again as i click more links. I have issues with the
system lagging. My mouse clickings, typing into forms, opening new
tabs, clicking links all take a noticeable lag and i have to wait for
it to complete to see the results. Some sites that are web intensive,
Google Reader, youtube.com, espn.com do cause the 100% utilization.

I can surf youtube.com without problems but if i play a video it
stutters as it plays and i have trouble performing tasks on my
computer. On google reader, i continue to get "oops...there was an
error" after each article and the site takes a good 10-15 seconds to
refresh with new articles/feeds.

I used to use firefox2 and i thought that it was the culprit and
changed to IE7. however, IE7 didn't make much of a difference. My
windows programs don't lag too much, except for WMP11, but i think
that's because it uses an Internet connection, but that's my reasoning.
When i start up the computer fresh, it works great, and everything
performs well. But the triggers (wmp11 ie7) cause it to begin utilizing
100% CPU. I've tried using process exp and i have a screen shot here.
It was taken after a few minutes of my restart and the cpu settled
down.

I am computer competent and have been able to resolve my comp issues
but this one seems to be a hardnut to crack. I've us virus scanners,
spyware removers, sfc /scannow and nothing has shown up. I dont want to
reinstall XP again because i just did it a few months ago. Its a system
lag and not a system crash so i can bear with it and but have restart
often to keep working but (out of laziness) i rather fix the problem
than just reformat.

I am not sure but i think it might be a driver conflict or some process
hogging the cpu. umm, i try to keep my drivers up to date and most of
them are. Or i'm thinking its some program/driver/device using my
internet connection. i cant be certain of them all though. I would
REALLLY appreciate any one's advice and help to fix this issue of mine.
Its been over a month and i want my computer back to normal.

Hi Priyank:
I have been having the same problem and have tracked it down to a probleb
caused by auto updates.

When your cpu usage goes to 100% call up task manager (alt-ctrl-del) and
look at svchost.... is it running 90-100% cpu usage? and is wuauclt.exe
running under it?

wuauclt.exe is the auto update program (dll?) used by XP, windows defender
and Office to check for and upload new updates.

I suspect there is a bug in it and it is causing problems. I have a problem
report into Microsoft and i am trying to convince them this is a real
Problem!
My Microsoft Incident number is SRZ061102000815 You should send in a
problem report too and quote my number as a reference.

If you google or search for "SVCHOST" or "100% CPU" you will find many
others are having this problem too. We all need to complain to get somebodys
attention.

Mark.

you are right! same here. I disabled this service and smooth sailing since
then. I turn it manually every week to update...

wow what a difference, i forgot my computer was this fast...

i googled around and I found this site
(http://episteme.arstechnica.com/eve/forums/a/tpc/f/12009443/m/786004271831)
that has a deeper discussion going on.

Here is one posters (jwnin) advice:
We've encountered this too. The following usually helps, although it's
not a preventative measure, only a corrective one:

Temporarily stop the automatic updates service. (you should see CPU
drop)
Download http://go.microsoft.com/fwlink/?LinkId=43264
Run WindowsUpdateAgent20-x86.exe /wuforce
Rename C:\windows\software distribution to C:\windows\software
distribution.old
Rename C:\windows\windowsupdate.log to c:\windows\windowsupdate.log.old
restart the automatic updates service.

mark, i would like to make an incident report to MS but i want to know
more first. from the symptoms i've been expereincing which of the ones
are common to yours?

other symptons i forgot to mention:
1. slow download rates (50-60kb/s)
2. pandora.com causes very slow cpu levels too

these are before i made the suggested fixes... i will continue to check
my cpu for changes and keep posting here.

As someone else pointed out, disabling "security center" service also works.
Perhaps this keeps the auto-update working.

control panel->administrative tools->services
