Re: cpu usage 100% then 20% every second

Tech-Archive recommends: Speed Up your PC by fixing your registry



I SPOKE TOOOO SOON!
I rebooted and it is back.
On the first graph (process explorer) cpu usage goes from ~2% to 100%
and back in 3 seconds in a sine wave.

I don't see any processes that I don't recognize and none of them go
above about 2%.
When the SYSTEM process goes to 100, I don't see a corresponding
increase in all the other prosesses combined.

You need to find the specific system process that's taking all (there are
lot of sub-processes tied to the 'System' process) the CPU resources and
slowing down your PC.

To do this 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 'Show Lower
Pane' options.
(This will provide the detailed info you need)
Next click on the CPU column to sort processes by %CPU usage.
Then click on and expand the 'System' process and identify the sub-process
that's using most or all the CPU %.
Click on and Highlight the sub-process of interest, right click and from the
options listed select: google, This should display what out there on the web
about that process.

Note: some entries like Explorer, System process and svchost may need to be
expanded to show the detail, (sub processes), in this case click on the +
located to the left on the entry.

Another tool to look at is named: What's Running

cpu usage is varying from 20% to 100% every second.
process doing it is SYSTEM - the one above SYSTEM IDLE PROCESS.
