Re: Services running high and CPU usage high

I have no idea why the RPC should be consuming so much CPU time.
There are a couple of thoughts that went through my mind:
- When you invoke the command "services.msc" then you can
see all your current services, including RPC. After double-clicking
it and checking the "Dependencies" tab, you can see the many
services that depend on it. By disabling some of them selectively
from the main Services screen, you may be able to rack down
the culprit.
- WMI (Windows Management Instrumentation) is a known hog
of CPU time. You can turn it off from the Command Prompt like
so: net stop "Windows Management Instrumentation" without
any ill effect. If it is the culprit then the excessive CPU loading
will stop immediately.
- Virus scanners and background indexing tools (e.g. Copernic)
can also cause a lot of background activity. I would temporarily
uninstall my virus scanner and third-party firewall.

Thank you Pegasus for your help.
I have downloaded the Sysinternals Suite, it is a great tool.
I hope that I am using it correctly.
I see in Services properties and under the Threads tab that most of
Services
usage goes through RPC (Remote Procedure Call).
I studied it and learned that it is a necessary service and can not be
disabled or stopped because other services depend on it.
Do you have any idea why RPC is using so much CPU?
I have another older computer (Pentium 3) and on that one everything is
fine.
I just opened for services the lower pane and under Handles there I can
see
that there are many items: for example many emply "Mutant" and "Semaphore"
handles. Would that make any problem?
I am using this tool for the first time and I don't know how to interpret
all data that I see.
Do you have any idea why my RPC is using so much CPU?
Your help will be greatly apreciated.
Thank you in advance.

Hello everybody,
Lately my HD is spinning like crazy and fans too.
I looked in Task Manager and I can see that services are running very
high
and CPU usage is high also even when I do not perform any tasks.
I scanned my computer for viruses and it seams that it is clean.
A few weeks ago I installed Spybot and BitDefender but I uninstalled
them
soon because I thought that they may interfere with eachother.
I ended unnecessary processes - now running 30.
I have also unticked non essential Start Up programs and Services -
that
did
not help.
To me it looks like there is something running in the background but
how
can
I detect it ??? It must be hidden somewhere.

My computer parameters:
IBM ThinkCentre
CPU 3 Ghz
RAM 2 GB
HD 233 GB (194 GB free space)
WIN2000 Pro with SP 4.
AV software- Avast.

I have this problem for the last few weeks and it is driving me crazy.
I
spent countless hours trying to find the cause.
Please provide any suggestions.
Thank you in advance.
John

I would run procexp.exe (www.sysinternals.com) to identify the service
that's hogging the CPU.
