Hibernation and CPU usage

[Guest]

After my computer awakes from hibernation the cpu usage is around 20% and the
system slows slightly. I can't find any process that is using the resources.
What could this be caused by?

Thanks,

R-click in Task Bar, take Task Manager, look on the Processes page.
Make sure View - Select Columns is set to include CPU Usage [%] and CPU
Time [total so far], and probably useful to have Memory use too. Then
see what those tell you

Yes, I do that but it doesn't give me any clue what is using process is using
the cpu resources. Everything shows zeros except System Idle shich bounces
between 99 - 100%.(I know those SI readings are normal) Is there any other
way to see what is using the CPU?

Then what gives you to believe that something *is* using the CPU? If
system idle is using 99% then nothing else is

At the bottom of Task Manager in the status bar the CPU Usage bounces between
18 and 22% (usually) and the performance tab also shows that same usage.

I remember a problem in SP1 when CPU would be slow after return from
Hibernation. There were hotfixes available for that. Or you can try
installling SP2.

Thanks. I am using XP Home SP2

In that case the sum of individual processes (System Idle excluded)
should match. I can envisage a case of malware hiding itself that
resulted in SI being lower, but no process shown to account for the
discrepancy, but not a level in the bottom bar like that with SI up at
99

I'll run a check for spyware. Could this be caused by Norton Internet
Security?
