svchost CPU spikes

Installed a machine at work with Vista business.
From the moment I log on I have a svchost.exe using 70% on core1 and 30% on
core2 for 2 seconds and then going idle for 4 seconds.
And it keeps doing that even if I don't have anything open or am doing
anything.
In resource monitor it says that the process is: svchost.exe
(LocalSystemNetworkRestricted).

Screenshot: http://resource.mezelf.com/taskmanager-vista.jpg
(The updatespeed was set at high.)

Machine : Intel C2D 1,8 with 3 GB memory
Mainboard: Asus P5B-E

What could be causing this?
This problem started right after install even. :S

If you right-click that process svchost.exe in Task Manager, and choose 'Go
to service', you can see which services it is hosting, which will help you
to pin down which particular service(s) is/are causing the 'spikes'

I found that the service runs:
AudioEndpointBuild
CscService (offline files)
hidserv
Netman
PcaSvc (prg comp. ass. serv.)
SysMain (superfetch)
TabletInputService
TrkWks (Distr. Link track client)
UmRdpService
UxSms
WdiSystemHost
WPDBusEnum (Portable Dev. Enu. serv.)
wudfsvc (Wind. Drv Foundation)


I could stop all of them except wudfsvc (windows doesn't allow stopping that
one)
All didn't help.

A fear haunts me that perhaps only a reinstall of the machine might.
As the service tab doesn't show activity as a help to nail down the specific
process.

msconfig (Start > msconfig) is a good tool for trouble-shooting that kind
of issue.

You could experiment by disabling some of the potential culprits in your
list (unchecking them via the Services tab), and see if the problem
disappears with a reboot. If it does then you have your culprit.

After 2,5 hours and lots of reboots I got it down to 'Plug and Play'.
Which makes that I will have to life with it unless I reinstall.

Good job in pinning it down. Might be a particular device that you've got
attached to your system that's causing the problems.

Nothing special in the machine:
Asus P5B (with onboard LAN and audio)
ATI radeon 550
and the usual HDD/DVD

Make sure you have the latest BIOS. Many Asus boards need a BIOS update to
work properly with Vista.

Checked the BIOS and it's on the latest version for it.

Hi,

I'm struggling with a similar problem, exept with me it seems to be
the "sysmain" or "superfetch" service. Stopping this service (or
disabling it in services.mcs) stops the CPU spikes.

I just want to know whether or not this service is critical for my PC
and of there is some kind of update available to fix this problem.

Thanking you in advance...
