I have a quite new computer so i havent really looked on the taskmanager before. But today when i started the computer i thought it was running slowly so i checked it. Cpu Usage is constantly at around 40%.
there is 2 processes with svchost.exe, one taking around 25% and the other one taking around 12% of cpu usage.

I checked the services on one of the svchost:
Plug and Play
DCOM Server Process Launcher

And i saw in another thread that you could check the threads running under svchost with Process Explorer, the ones consuming cpu power on both the processes had Start Adress:

My system is Windows Vista Ultimate SP1, AMD Phenom 9550 Quad-core 2.20GHz, 4GB RAM, 64 bit operating system.

Unfortunately Vista runs a lot more background services and scheduled tasks than XP. Or put it this way, it keeps your cpu and hd busier than XP did. You can look at this site for ideas which services you may want to disable or set to manual to take off some of the system load.

edit: btw it's a good idea to set a Restore Point to get back where you started if you should
disable something that should not be disabled. :huh:

Proceed with care. On my system after a few of the obvious ones I started keeping a log. I'd try setting one service to Manual Stopped or Disabled, note it in the log, then run it for awhile. If things started seeming weird I had a note of exactly what I did so I could back it off. If you change multiple things at once it's easy to get lost. :huh:

Which of the svchost.exe contained the PnP and DCom stuff - the 25% or the 12%?
What were the services for the other one?

If you notice the svchost.exe in the main Process Explorer window, you may notice that the are several services just below it that are indented - what are they? On my system I've got 3 of them underneath this particular svchost.exe process (in addition to the PnP and DCom that you mentioned).

Also, if you've only got the ntdll.dll file as a thread under that svchost.exe process - then there's a lot of stuff missing (mine has 8 entries in the Threads window).
