CPU Usage very high

The CPU usage on my Compaq Presario running at near 100%. It has happened
before I got round it by reformatting and reloading all my software but it
has happened again recentlly. Last known major operation was loading Windows
SP3.

I have done a system restore to an earlier point to no avail.

Process shows 58 processes running with one (there are many files with this
name)
svchost.exe SYSTEM consuming 97-99% of CPU usage. Terminating that process
drops the CPU usage to 20%.

Anyone any suggestions as to how I can fix this seemingly recurring propblem.

Is it something to do with an application loading at Start UP?

How do I see what is set to load at start up?
What application do I need at start up for Windows to run OK.


I feel I have a lot loading that I do not need.
 
There is a know problem and you might be effected by it.
First see the Microsoft KB article:
http://www.microsoft.com/downloads/...CD-A0B9-497E-8A89-404327772E5A&displaylang=en

Then read and follow the instructions posted here:
http://msdn2.microsoft.com/en-us/library/aa387285.aspx

To find out more about Svchost.exe entries try Process Explorer:
http://www.microsoft.com/technet/sysinternals/SystemInformation/ProcessExplorer.mspx

Once you have Process Explorer installed and running:
In the taskbar select View and check 'Show Process Tree' and the
'Show Lower Pane' options.
(This will provide some of the detailed info you may need)

Next expand the Process tree until 'Services.exe' has been expanded.
Next move the mouse cursor over the Svchost.exe process that you are
interested in. (You should now see a pop up with a list of services
associated with the Svchost.exe you selected)
Note: some entries like Explorer, System/Services, and
Svchost entries may need to be expanded to show the detail
(sub processes), in this case click on the + located to the left of the
entry.

Next double click on the Svchost.exe process that you are interested in.
The 'Properties' Window should now be displayed with numerous tabs.
(Two important tabs to look at are: Services and Environment)

Searching for web based information about a process:
Then mouse over the specific process that's you are interested in.
Next click on that process to highlight it,
Now that it's highlighted, right click and from the options listed select:
Search Online
This should display what out there on the web about that process.

As mentioned before: You can also double click on any process
to open up a more detailed 'Properties' window.

Another tool to try is: What's Running

I second the suggestion by JS that you use Process Explorer to identify
the cause of your problem.

Your post does not make clear the command line of svchost.exe giving the
problem. My guess it is either:

C:\WINDOWS\System32\svchost.exe -k netsvcs

or

C:\WINDOWS\System32\svchost.exe -k LocalService

A common problem relates to the wuauserv, which is covered by netsvcs.

Thank you both for taking the time to reply, I gave as much information as I
could at the time. I will look into what has been suggested.

I terminated the svchost.exe showing high usage and things seem to be
running normally today but will do a little more investiagtion when I have
time.

I am currently running without SP3 installed having restored to pre the
installation. Are there any known issues with SP3 which might cause what I
experienced?
