browser hangs periodically.

[test]

Hi,

I am having Gateway computer with Windows XP OS. I will mostly use mozilla
browser,but this is occuring even for Internet explorer. Actually whenever I
use the browser after I use for 5 seconds it hangs for 3 secs and then comes
alive. This happens every few seconds periodically. So I went into the task
manager and saw what is process that is causing this. I noticed that,when
ever browser hangs ,the System process(not system idle process) is taking up
cpu by 40% and hence the browser hangs.
This is so frustrating that I am not able to do daily regular work properly.
If some one can help in this regard that would be really nice.

Thanks.

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

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 some of the detailed info you need)
Next click on the CPU column to sort processes by %CPU usage.
Then click on and expand the 'System' or 'Explorer' process to expand and
identify the specific sub-process that's using most or all the resources.
Next click on the sub-process or process listed under the System Process
that's using most or all the CPU %,
once it's highlighted, right click and from the options listed select:
Search Online
This should display what out there on the web about that process.

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

Hello,

If you are running Internet Explorer 7, try running it with add-ons
disabled.
Start > Programs > Accessories > System Tools > Internet Explorer (No
Add-Ons)

Try reproducing the problem again. If it doesn't appear again, one of your
add-ons are causing the problem.

To disable add-ons (applies for IE6 too), start Internet Explorer as normal,
Tools, Manage Add-ons, Enable or Disable Add-ons. Disable all the add-ons
and enable them one by one till the problem appears and you get the culprit.

Hi JS,
Thank you for the response. Yes I have donwloaded ,installed and ran the
application and did what ever you have suggested.
I tried to use the browser again and observed the process explorer cpu %
time. What I found then is, System process 25%, firefox process 25% and
system idle process 50%.
However none of the process under the System process node is having any cpu
%. So I am not able to figure out which process is taking up the cpu time
and causing the computer to slow down.

Please advise what I need to do now. Eagerly awaiting your response.

Thanks.

Double click on the System Process, this should open a System Properties
window (the window name will also the Process ID number)
Next click on the 'Threads' tab.
In the Threads display sort by the CPU usage column.
Now in the 'Start Address' column you should see various entries floating up
to the top of the list (A common entry is one named 'ntoskrnl' which can be
ignored), one of these entries is the one that's eating up you CPU time.
If your quick with the mouse highlight it when it is at or near the top of
the list.
Now in the lower right near the bottom of the window click on the 'Module'
button.
This will open another window which has three tabs (General, Version and
Digital Signatures).
Click on the Version and Signatures tab to identify the guilty software.

Hi JS,
Thanks for the quick response again. I did exactly what you have
articulated. I tried many times and for many entries in that and found the
module is "C:\WINDOWS\system32\dllcache" which corresponds to "NT Kernel &
System". Do you think this is one? Some how i am skeptical about this.
Please help. Looking forward eagerly to your response.

Thanks.

If there is a lot of activity associated with the
"C:\WINDOWS\system32\dllcache" folder you could have a virus. This is a
hidden folder so if you are going to look at the contents make sure that you
have Windows Explorer set to show Hidden files and folders.

Have you run an AV scan lately? If not do so, don't panic as I could be
wrong on this!
