CPU Usage 100%

[Guest]

Recently (the last month or so) I have been having a problem with CPU
usage. Sometimes when I finished playing Civ III for an extended period of
time I would notice that my entire computer was running extremely slow. I
would bring up the task mananger and check the perfomance tab and the CPU
Usage section would say 100%. To remedy this (temporarily at least) I would
shut down the computer and then turn it back on. This usually fixed the
problem and I just accreditted it to playing Civ III for too long (if any one
has played any Civ games, you can understand how playing for "just an hour"
often turns into more).
This morning however, I logged onto my computer, and it was already
running slow, I checked the task manager, and it said 100%. So I tried my
normal remedy and it didn't work. Now the performance tab says noting but
100% usage, even when I have just logged on and no programs are running. I
don't know a whole lot about computers, but this seems like sometinhg akin to
a car redlining. I have tried shutting the computer off and leting it sit
before turning it back on with no success. Any posts would be greatly
appreciated.

What are your anti-virus and anti-spyware arrangements.

Task Manager is useful but you could look at another freeware utility
Process Explorer, which provides similar information but adds that
little bit extra towards seeing what the running processes represent.

For further information about Process Explorer see here:

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

To ascertain which service is causing the problem select the
image name producing the high CPU usage, right click,
select Properties, Services. Note there are the full names and some
explanation of what each service does.

You will find further information on Services here:
http://www.theeldergeek.com/services_guide.htm

To trace the particular Service involved you need to turn off each
service in turn and then restore it noting what effect it has on CPU
usage. However, you need to take care and watch what other Services are
dependent on that service. When you click on the Dependencies tab allow
it a little time to display the information.


Hope this helps.

First off, thanks for the post. I downloaded and ran the program Process
Explorer, and it showed that the Explorer was using 98.64%-100% of the CPU
(it kept alternating back and forth). I then right clicked and selected
properties for the Explorer, but there was no services tab. Anyway, like I
said previously I do not know a lot about computers, but I know that I can
not simply end the Explorer process.
I am unsure where to go from here, just looking at Process Explorer I
have no clue how to use it, and the Help tab provides anything but. Running
Process Explorer takes alot of patients simply beacuse everything is running
very slowly and navigating the Help contents proves frustrating.
As for my anti-virus and anti-spyware programs I mainly use Microsoft
AntiSpyware and Spybot S&D.
P.S.: Could the CPU usage running at 100% all the time cause any damage to
my computer? Thanks.

I don't see an AV scanner listed in your post, get the stinger and run it to
see if you are infected and or run an online scan, see links..
http://vil.nai.com/vil/stinger/
SB8 will delete infected files, set it to prompt you first so you can keep
track in case system files have been compromised..

I have frequently used the above scanners without problems..

Jaymon, I tried the anti-spyware/anti-virus programs, and they came up clean.
They took forever to run, as everything has slowed down to molasses speed.
I updated all my anti-virus/anti-spyware programs and ran them again,
nothing. All I know is that my CPU usage is at and seems like it will remain
at 100% indefinitely.

I think I have found the problem. I ran process explorer again and right
clicked on Explorer and selected properties. Under the threads tab I noticed
that one thread was consuming anywhere from 40% to 98% of the CPU usage. So,
I suspended it and the CPU usage dropped from 100% to about 3%. The name of
the thread is, “webctrl.dll+0x12df.†I have no clue what the thread does or
if it is legit or faulty. The context switches on the thread are 30000,
which when compared to the other threads is enormous. I do not know if I
need this thread or if I can permanently delete it.
The first time I typed a response after I suspended the thread it didn’t go
through. Now I am wondering if this “webctrl†thread could have had anything
to do with it. I will enable the thread and see if this response will go
through.

I hope you got it to work. I would highly recommend this website:

http://www.answersthatwork.com/

Download their program: The Ultimate Troubleshooter
It is a very good program to tell you exactly what is running, why it
is running, and what options you have as far as what to do with it. The
support is second to none. I've found it very helpful and I've learned a
lot about the different processes by using it. Really helps speed up
boot up and general system performance. Hope this helps.

Could be related to an anti virus program, or was affected by a virus that
might have been removed and left or created a bad thread..You may be

MudBug, I downloaded and ran TUT, and navigated to explorer, webctrl. It
just says that "this version of TUT does not have information for this task."
Thanks for the post, but I don't know what else to do with TUT.
