Re: CPU Pegged at 100%

I know it's the holidays, and that's why responses may be slow, but I'm still
looking for help.
Any idea if Intel's Application Accelerator would be helpful with this kind
of situation? Just been poking along, trying to check on drivers etc, and
stumbled across it.

Your commit charge figures are well below available RAM so in that sense
they are fine. In terms of comparables posted these will have been
posted as a result of requests where the user has complained of slow
performance and excessive use of the pagefile is expected. So any
results posted will more than likely be high. However, it is not easy to
get typical figures. You really need to get results when the user is not
conscious of a performance issue.
Leaving a computer on 24/7 exposes the system to the consequences of
memory leaks. Even when a programme with a memory leak is closed the
memory is not released until the system is shutdown or restarted.
You can check pagefile usage more directly using pagefilemon.
A small utility to monitor pagefile usage:
http://www.dougknox.com/xp/utils/xp_pagefilemon.htm
Note that programs using undo features, particularly those associated
with graphics and photo editing, require large amounts of memory so if
you use this type of programme check these first observing how the page
usage increases when they start and whether the usage decreases when you
close the programme.
You can get clues as to what is generating peak memory demands but this
is not a precise science, more a matter of judgement.
The basis of your complaint is that CPU is pegged at 100%. Are you
counting the System Idle process as part of the 100%. The System Idle
process needs to be disregarded as it represents unused CPU capacity.
Normally if you can match CPU usage to something you are doing then it
is of no concern. It is unexplained CPU usage that needs investigation
as it can indicate malware activity. You can also get a programme
commanding 100% because it has a problem. Windows Automatic Updates has
been known to create this type of problem.

Gerry-
Under normal circumstances, what would average commit charge figures
be? Just curious, because the examples I've seen on line have been
roughly the same as on this machine, so I'm wondering what the metric
is that you use.
Also, I've heard conflicting arguments for shutting down frequently
vs. leaving a computer on for longer. Some involve the strain on the
hardware from frequent power cycles, some involve software stability
over long periods of time. Why do you say it is "not a good idea" to
leave the computer on 24/7?
I'll try the spybot thing. I think that McAfee had said that it
conflicts with their software and that it needed to be removed, but
I'll double check those conversations and give it a try.

Your commit charge figures are high. McAfee is a known cause and two
of the items in your list relate to McAfee. Leaving your computer on
24/7 is not a good idea.
You might look for malware.
I would download and run Spybot S & D (freeware version) and see if
it finds anything like a Trojan. If Spybot S & D finds anything
significant ( other than cookies) you need to be wary. If it removes
something and it returns or another nasty pops up it can be an
indication that there is another hidden nasty not being detected by
McAfee or Spybot.
Spybot S & D. There is a freeware version buried in this link:

Just wanted to make sure my responses were actually getting out
there, since my ability to see them has been very compromised by
using the Microsoft web-based newsreader. Figured I would ping this
one, just to make sure that if the existence of the other replies
had been unobserved there would be another chance for a response.

What version of McAfee is it?
I do not know whether Windows Defender clashes with McAfee but I
doubt that is the problem.
Try Ctrl+Alt+Delete to select Task Manager and click the
Performance Tab. Under Commit Charge what is the Total, the Limit
and the Peak?
You should be able to gather more information from Task Manager.
With the Processes tab open select View, Select, Columns and check
the boxes before Peak Memory Usage and Virtual Memory size. What
are the figures for the 6 processes using the largest amounts?
Do you leave your computer on 24/7?

Sorry, it's actually 1.25 G. System came with 500M (250x2). I
bought 1G and replace 1 module.
In Task Manager, the total physical memory is : 1308656. Total
available hovers around: 583560, and system cache around:
654840.
Any idea if Windows Defender and McAfee clash at all to cause
these kinds of symptoms. It's still strange to me that the
biggest hog I wind up seeing is svchost.exe with 3 identical
threads kernel32.dll!CreateThread+0x22.
While McAfee may be somewhat of a hog, it doesn't "appear" to be
grabbing too much of the CPU (except at certain times).

In terms of system performance McAfee is a poor choice for a home
computer. Replacing it with freeware alternatives would result
in a significant improvement.
Are you sure you have 1.3 gb RAM? You have two slots. What size
stick is each?

On SP3 now...got THAT issue resolved, but performance still the
same, LOUSY. Updated video driver, no effect. You mentioned the
motherboard chipset drivers and that they should be sure to be
updated. If I go into device manager, which devices do I select
in order to update those drivers appropriately? Is there a way
to get the system to do a global driver update of some type,
rather than having to do them piecemeal??
Thanks.

I've seen this issue a number of times, but no firm solution,
and have a few differences with the other presentations. Just
want to try to get at what's going on with this machine.
HP Pavilion 503n, XPSP2, Celeron 1.7GHz, 1.3 GB RAM
Running Process Explorer to try to figure out what's going on.
Launch an Office program - Jumps to 100% CPU, then drops down.
When I then try to open a file and navigate to My Computer,
the flashlight comes up, and it takes forever, with the usage
up to 100%. The primary process in this case appears to be
the Office App (eg - WinWord). In other cases, seems like
it's svchost that has 3 threads of
kernel32.dll!CreateThread+0x22.
These each consume 20+% of the CPU.
When we connect to the web using VZAccessMgr (verizon wireless
connection) the usage jumps from about 20% up to 80% and back
down. Just keeps cycling like that. The heavy users in this
case appear to be the CreateThread+0x22. Then when anything
else runs on top of that, we have absolutely no functionality
at all.
Any help/suggestions appreciated!!!
I tend to see that alot on celeron processors. The lack of
sufficient cache on the processor *really* makes a noticable
difference.
- Are you running the latest VZAccessMgr?
- Latest hardware drivers (motherboard chipset in particular)?
- What AV software?
- Integrated or seperate video card (and is the latest driver
for that installed?)
- What is your virtual memory set at? (I suggest you let
Windows control it.)
- How much free disk space?
- Last time you ran a full CHKDSK?
- Followed by a full defragmentation?
- What version of Office?
- Why SP2 and not SP3 for Windows XP?
- Home Edition, Professional Edition, Media Center Edition or
Tablet PC Edition?
- If you run an application like "HeavyLoad" for a while - does
it crash your system? And how long does it take to completely
peg your processor and use all your memory?
