I don't know why this is happening, but I often find that my CPU usage

goes up to 100% and will not come down until I reboot. If I get the

Task Manager up it says that no applications are running, so it must be

from a background process. I've run full scans with Kapersky

Anti-Virus, Ad-Aware and Spybot and it seems to be all clean. XP is

fully updated too. Is there a way I can find out which program is

causing this? It's annoying to have my system slow to a crawl every

day, and with the CPU temperature going through the roof.

In the task manager, click "processes" tab. In this screen, go to the "title"

bar, click CPU, and it'll give CPU usage by "%", either ascending, or

descending depending order, based on the number of times you click.

 

For instance, I have AOL software I use, and they got these annoying

processes running in the background on bootup, whether I have AOL on or not.

Right now, it's eating up about 50% of CPU usage, which means if I don't turn

it off, anything else I turn on would get CPU up to 50%, meaning, slowwww.

 

After you figure out which of these processes are, and they usually get

there on bootup, then, you'll have to eliminate them in the bootup process.

Download Process Explorer.

 

For further information about Process Explorer see here:

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

 

To ascertain which service is causing the problem select the image

producing the high CPU usage, right click, select Properties,

Services. Note there are the full names and some explanation of what

each service does.

 

You will find further information on Services here:

http://majorgeeks.com/page.php?id=12

 

To trace the particular Service involved you need to turn off each

service in turn and then restore it noting what effect it has on CPU

usage. However, you need to take care and watch what other Services

are dependent on that service. When you click on the Dependencies

tab allow it a little time to display the information.

You have to look at the processes list in Task Manager to see which one is

hogging the CPU cycles. At any given time you will have 30-60 processes, or

more, running in the background. These are typically Windows services,

drivers, software background processes, TSRs etc..

 

If you install Process Explorer or a similar program it will also the

identify handles and DLLs associated with each process, which may help you

further to identify the problem. For example if Explorer.exe is using 90% of

CPU cycles for no apparent reason it is often due to a problem media file or

the CODEC associated with the file type. Process Explorer would show the

active file handle and allow you to close it (thus releasing the CPU). Then

you can correct the problem, one way or another. Alternatively some software

you installed might have placed an obsolete version of a Windows system file

on your computer and that could be the source of the problem.

The most usual cause recently for the 100% svchost usage is

a problem with the Windows Update Service which is fixed by upgrading to the

Windows Update Agent 3.0, v. 7.0.6000.374, for 32 bit machines is available

here:

http://download.windowsupdate.com/v7/windowsupdate/redist/standalone/WindowsUpdateAgent30-x86.exe

and installing the updated KB927891 hotfix, here:

http://support.microsoft.com/?kbid=927891 for a complete fix.

I used Process Explorer when the problem came back, and it was

immediately clear that AdobeUpdater.exe is permanently using between 96%

and 99% of the CPU cycles. I have not long updated to the newest

version of Adobe Reader, so I'm sure that is the problem. As soon as I

come across the need to view any Adobe content, either online or

offline, it appears to be that is when the problem starts. Even exiting

all adobe software does not stop the problem, as AdobeUpdater.exe still

runs in the background until I reboot. Just Googling the file name

brings up multiple similar experiences. Thanks for everyone's advice

and help.

If you only use Adobe to read document you might find Foxit Reader

a more satisfactory programme:
