Guest

My explorer.exe process goes insane when my pc have been on for a while.
Using 50% of cpu and stealing 200+ MB of RAM. No viruses. Have read about
similar cases on the web, but no one seems to have a fix?! :( The PC can
work fine for hours at a time, but suddently it becomes slow. When i look in
task manager, explorer.exe is throwing a fit, using cpu and ram described
above. The only solution is to kill the process and restart it. Please help
me!!

Check if the indexing service is launched...

In Task Manager :
C:\WINDOWS\system32\cidaemon.exe
and
C:\WINDOWS\system32\cisvc.exe

This service is resource hungry and... useless.

You can disable this service that way:

Start | Run | services.msc

select this service, stop it and select disabled.

Let us know.

Well, something else...

Try this :

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 /R /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

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

b)
To find recent drivers

www.driverfiles.net [In Eng.]


5) 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

6) 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...)

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

Autorun
http://www.sysinternals.com/ntw2k/freeware/autoruns.shtml
*Don't delete anythings unless you are absolutly sure of what's you're doing*

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

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

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

9) 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 keyEnablePrefetcher REG_DWORD must be set to 3.

10) Safe & Cool ...

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

Some tools and links:

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

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