You can use an Intel Application Accelerator with the Intel Chipsets
listed in this link.
http://www.intel.com/support/chipsets/iaa/sb/cs-009312.htm
An Intel Application Accelerator is not offered by Intel for later
chipsets
Did you disable McAfee and Windows Defender before running Housecall? It
would be helpful to know whether the problem was a fight between
security software or defensive measures being taken by malware? It could
of course be something else.

Tried the housecall link. Looked like it was working ok at first,
but then took FOREVER. There was no data going across the web, so
something hung up, and the CPU was, again, at 100%. Tried to restart
the housecall check, and it kept giving me error messages, so I don't
think I'm going to be able to successfully run that. Any other
ideas???

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:

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

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?
