processes?

[Guest]

When I go to Task Manager, under the process tab. I show system idle process,
CPU at 90 and above is this normal? CPU Usage jumps around like crazy, but I
can't find anything running in the background. My computr is taking forever
to load on start up. I've done the spybot, ad-ware, and spy doctor scans. and
it comes up clean. What else should I try? Thanks for any help you can give
me.

I, myself, am idle most of the time. :-D

System Idle Process reference...

[[Note The System Idle Process indicates the unused percentage of the CPU.]]
Task Manager may not calculate CPU usage correctly on Windows 2000, Windows
Server 2003, or Windows XP
http://support.microsoft.com/default.aspx?scid=kb;en-us;873289

[[System Idle Process - You cannot end this process from Task Manager.
• This process is a single thread running on each processor, which has the
sole task of accounting for processor time when the system isn't processing
other threads. In Task Manager, expect this process to account for the
majority of processor time. ]]
Default Processes in Windows 2000

[[Description:
the System Idle Process is not a process, more a counter which is displayed
in WinTasks used for measuring how much idle time the CPU is having at any
particular time. This counter will display how much CPU Resources, as a
percentage are 'idle' and available for use. Cannot be killed]]

[[System Idle Process
An option in the Windows XP Task Manager that indicates what percentage of
time the CPU is currently doing nothing but waiting for work. If no
applications are running that the user is aware of (although there may
always be some tasks running in the background), the percentage can be in
the high 90s. ]]

[[System idle process
In computing, The System Idle Process is a process in the Microsoft Windows
operating system that displays, as a percentage, how much CPU resources are
"idle" and available for use at any given time. The name of this "process"
may be a misnomer, however, as the System Idle Process is more of a counter
and less of a process that actually uses the resource percentage that it
displays.]]

Bonjour *jct883* :

When I go to Task Manager, under the process tab. I show system idle process,
CPU at 90 and above is this normal? CPU Usage jumps around like crazy, but I
can't find anything running in the background. My computr is taking forever
to load on start up. I've done the spybot, ad-ware, and spy doctor scans. and
it comes up clean. What else should I try? Thanks for any help you can give
me.

System idle = when your system do "nothings"... absolutly normal

To have a better overview of what's running in your PC I suggest you
Process Explorer from Mark Russinovich :
http://www.sysinternals.com/Utilities/ProcessExplorer.html

Normaly a well maintened XP boot in an average of 30 seconds...
Like this:
http://cjoint.com/?gmt2p0KVni

Check list for maintenance :

A)

1- Set explorer to use à different process (multi-threads):

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
Create this key:

DesktopProcess
Reg_DWord
value 1

2- Change the Windows priority separation :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PriorityControl
Create this key :

Win32PrioritySeparation
Reg_DWord
Value 26 in HEX


B)

A good maintenance of W xp is required from time to time.

Here some hints:

1- Use chkdsk to check the integrity of your hard disk:

Windows explorer | right click on disk icon |
properties | tab "tools" | "check errors" | check both options
ok and restart your computer

or

Start | Run | cmd | chkdsk X: /F /V ,
Where X= disk volume

For the results un applications log:
Souce : Winlogon
ID : 1001

2) Clean the temporary files:

Start | Run | cleanmgr.exe

3) Defrag the volumes of the HD :

Start | Run | Defrag.msc

For multiple volume defrag use this:
http://www.dougknox.com/utility/scripts_desc/defrag_all.htm

4) Check devices and drivers and upgrade them if needed

Start | Run | devmgmt.msc

Devices error codes:
http://support.microsoft.com/Default.aspx?kbid=310123

To find the drivers check the manufacturer links in Everest.
The drivers must comes from the manufacturer and nobody else...

5) Check the errors and warnings messages in the system and applications
logs

and , if needed, fix those problem as soon as possible. Some "errors"
messages are not important and can be ignored. Ask in new groups and
make some seach at Event ID site and with Google...

Start | Run | eventvwr.msc

Hints for Event IDs:
http://www.eventid.net/

6) Check the services configuration:

The mandatories services must be started and in automatic mode
The others in manual...or disabled....

More info on W xp services:
http://www.theeldergeek.com/services_guide.htm
if you understand french:
http://climenole.serendipia.net/archives/3-La-Configuration-des-Services-de-Windows-XP.html
(english version soon...)

7) Check the applications started at boot and keep them
to the minimum.

instead of using msconfig used Starter from CodeStuff...
http://codestuff.mirrorz.com/

Check for applications in your account and All users
(from an admin account...)

8) Control what's running on that PC with those tools:

Autorun
http://www.sysinternals.com/ntw2k/freeware/autoruns.shtml
*Don't delete or disable anythings unless you are absolutly sure of what's
you're doing* [as you know ;-) ]

Process Explorer :
(an enhanced Task Manager!)
http://www.sysinternals.com/ntw2k/freeware/procexp.shtml

9) Defrag the protected files ( Registry , hiberfil.sys, Pagefile.sys etc.)

http://www.sysinternals.com/ntw2k/freeware/pagedefrag.shtml

10) Optimize the prefetching

Run this command :
%windir%\system32\Rundll32.exe advapi32.dll,ProcessIdleTasks
usefull only when the computer is idle...
The service Task Scheduler must be running and in automatic mode.
Check this value:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory
Management\PrefetchParameters
The key EnablePrefetcher REG_DWORD must be set to 3.

11) Safe & Cool ...

A)
Keep your system free of malwares (virus, worms,spywares, etc.)

If you understand french:
http://climenole.serendipia.net/archives/5-Quelques-liens-utiles-pour-la-securite-de-Windows-XP.html
(english version soon...)

Check your firewall configuration and make sure your PC is "stealth":
www.grc.com
Run the "Shields Up" test .Everythings must be "green" ...

Update frequently your anti-virus and your anti-spywares.
( MS Anti-spyware, SpyBot S&D, Ad-Aware, Spyware Blaster and
Spyware Guard... more than one is better since no one are 100% reliable...)

And check if the AV is set to protect your PC "On Access"
(in the so-called "real-time") not only "on demand" ( scan
runned after the problem...)

Used an alternate Internet Browser and keep IE
only for Windows updates and MS specific stuff.
By alternate I mean :
Firefox or Opera (not Maxthon, Avant etc.)

Avoid to surf on the Web from an administrator account.

You have to "feed" your HOSTS file :

What is an Hosts file :
http://www.safer-networking.org/en/dictionary/hostsfile.html

The hosts from MVPs:
http://www.mvps.org/winhelp2002/
Frequent updates and documented...

Tools for Hosts :

HostToggle:
http://www.accs-net.com/hosts/HostsToggle/
and/or
WinPatrolgood also for other insteresting stuff...)
http://www.winpatrol.com/download.htm

Some tools and links:

"Mini- antivirus" to be runned in safe mode:

Stinger :
http://vil.nai.com/vil/stinger/

Avast cleaner :
http://www.avast.com/eng/avast_cleaner.html

MS:
http://www.microsoft.com/downloads/...e0-e72d-4f54-9ab3-75b8eb148356&displaylang=fr

Kaspersky:

Anti Root-Kits
F-Secure (beta)
http://www.f-secure.com/blacklight/

Online scan:

Anti-trojan:
http://www.windowsecurity.com/trojanscan/

Anti-spy:
http://www.spywareguide.com/txt_onlinescan.html
http://store.ca.com/dr/v2/ec_main.e...lient=ComputerAssociates&sid=35715&CID=181432

Anti-virus:
www.trendmicro.com

B)
Keep your PC free of dust and check the temperatures with those tools:

Everest:
http://www.lavalys.com/

Remark:
Very good software but the warnings about the Bios
and the commercial links to that stuff are useless...

Bios upgrades *if needed* must comes from the PC manufacturer
or the Motherboard manufacturer and nobody else.
(Not needed most of the time : don't worry about this..)

SpeedFan
http://www.almico.com/speedfan.php

Remark:
Good software but the temperatures of the hard disk are not
reported correctly and most of the time not related to the disk
reliability.
Better info from Everest...

No more idea....

Let us know.
