CPU at 100%

Got 3 XP Pro PC's that all of a sudden started CPUing at 100%, which means it
takes 4ever to boot and even then nothing can be accomplished to include
Internet, word processing, etc. I know it has something to do w/processes or
services or at least I think so but do not know how to tell which and what.
I'm not getting any errors just an hour glass that will go away and nothing
is clickable.

Does anyone have a clue as to how I figure out what's going on? All three
PC's started acting up around 8am today and all three have exact same
problem. All are on wireless network.

Any help will be greatly appreciated.

Click to expand...

Safe mode?
Safe mode with networking?
Checked to see what updates they recently installed?
Malware scans on any of them?
Disconnected them from the network?

What AntiVirus solution is installed?
What firewall application protects them and is it enabled?
What antimalware software (if any) protects them?

I would...

1) Give detailed information:

-- OS and exact version?
Start button --> RUN
(no "RUN"? Press the "Windows Key" + R on your keyboard)
--> type in:
winver
--> Click OK.

The picture at the top of the window that opens will give you the general
(Operating System name and flavor) while the line starting with the word
"version" will give you the rest of the story.

Post _both_ in response to this message verbatim. ;-)
(Yes - SP3 Windows XP Professional - this will go a little deeper.)

-- Antivirus application and version in use?

-- AntiMalware (if any) in use/scanned with already?

-- Any patches installed recently? Software? Hardware?

2) Disconnect one of them from the wireless network (turn off/disable the
wireless adapter.)

3) Using another machine (one without the issues) obtain the following three
programs and scan the machine now disconnected from the network with them:

Download, install, run, update and perform a full scan (separately) with the
following two applications (freeware versions are the ones to use for this):

SuperAntiSpyware
http://www.superantispyware.com/

MalwareBytes
http://www.malwarebytes.com/

After performing a full scan with one and then the other and removing
whatever they both find completely, you may uninstall these products,
if you wish.

Download and run the MSRT manually:
http://www.microsoft.com/security/malwareremove/default.mspx

Reboot.

4) Hook it back up/enable the networking.

During any of that - did the lone system run better?
 
I love it when things come together. The problem was the COMODO Firewall.
Apparently we all downloaded updates this am that caused the problem. Thanks
for listening and hopefully this will help someone solve a problem.
 
Turn off your Wireless Access Point and determine if the CPU loading
is normal with no network connection. If performance is normal then
re-enable the access point and only join the PCs to it one at a time and
monitor the CPU loading. You should also log in to the Access Point &
check the log.

It's doubtful a program update or other patch would affect all 3 in the
same way.
 
my suggestion is to initiate a
clean boot.

this would be one method to
eliminate processes that are
starting up and hogging cpu
and memory resources.
