Can anyone tell me why system idle process is using so 93% of the cpu most of the time.  My computer runs slow and there is definitely something going on.  I have scanned with Norton and Spybot and nothing is found.  I downloaded Process Explorer, and that is now I have the above information, but I am not sure just how to use all the information and what to do to rectify the overuse of the processor. 

I checked the Application Event Utility and the following was noted consistently as an error:

Event Type: Error
Event Source: COM+
Event Category: Unknown
Event ID: 4689
Date:  8/5/2009
Time:  6:11:58 PM
User:  N/A
Computer: DJLD2331
Description:
The run-time environment has detected an inconsistency in its internal state. This indicates a potential instability in the process that could be caused by the custom components running in the COM+ application, the components they make use of, or other factors. Error in f:\xpsp3\com\com1x\src\comsvcs\txprop\dtcinfo.cpp(158), hr = 8000ffff: TransactionManager->GetWhereaboutsSize

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

When I went to the above link, it had no information for this error.

The following was also listed in Application Event Errors regularlyEvent Type: Error
Event Source: MSDTC
Event Category: SVC
Event ID: 4437
Date:  8/5/2009
Time:  5:03:39 PM
User:  N/A
Computer: DJLD2331
Description:
The account that the MS DTC service is running under is invalid.  This can happen if the service account information has been changed using the Services snap-in in Microsoft Management Console (MMC).  MS DTC service will continue to start. Please make sure that the MS DTC service account information is updated using the Component Services Explorer.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
, and I have changed the service to start automatically from manual, but it does not change the error appearing.  I have never made any changes to the MMC as I am a stand-alone computer and don't have a network.  But some of the updates from Microsoft Update may have changed this entry and I cannot find information on just what needs to be done to keep the error from recurring:

 

Under System events the errors were as follows:

Event Type: Error
Event Source: Service Control Manager
Event Category: None
Event ID: 7034
Date:  8/5/2009
Time:  6:14:56 PM
User:  N/A
Computer: DJLD2331
Description:
The COM+ System Application service terminated unexpectedly.  It has done this 5 time(s).

Again there was no help at the site above on this error.

I hope that someone has found the solution to these errors, and maybe that will correct the system idle using so much of the processor.

I have a Inspiron 600m, SP3, Explorer 8, Intel Pentium M Processor, 1300mhz 1.29 Ghz 1.25 GB of Ram
