100% CPU Power - XP the Culprit, Not all These Different Causes & Fixes?

J

jcp370

I have been experiencing periodic bouts where my pc slows down to a
crawl and becomes virtually useless for at least a year, maybe more
like 2. I open the Task Manager and note that my CPU usage has reached
100%. I have read several hundred posts and tried half as many fixes
without success.

What continues to amaze me, however, is that these posts and proposed
fixes continue to target one particular program or add-on or villain
(spyware or malware, etc.) as the cause. And hundreds & hundreds of
individual offenders have been identified as the cause but the problem
remains unresolved for a lot of people, including me. And although
many posts claim success after implementing the various fixes, I'd be
curious to see how long these fixes lasted because I had temporary
success with a few of them. (And as an aside, spent a ton of money
beefing up my anti-spyware/malware security when this was repeatedly
identified as the culprit, only to experience no improvement at all.)

Has no one had experience similar to mine? When my pc is in its "100%
CPU usage mode", it doesn't matter what's running. As far as programs,
when it's in that mode, whatever is running, that's what's hogging the
power. I can turn off everything but 2 programs, for example, Word and
another small program using 3,808, no internet connection or web pages
open. If I close down Word, the small program will suddenly be using
90,000K. If I close down everything, it can still spike at 100%, this
time with miscellaneous things like msoffice, my anti-virus program,
svchost, etc. using up all the power.

In the posts, the most recent culprit is identified as the automatic
updates but I haven't had these enabled since I purchased the machine.
And the process goes on and on since I've been semi-obsessed with the
problem for a long time. I've tried what I could, read almost every
post but nothing has ridded my pc of the problem.

I had one period of about 4 months where the problem completely
disappeared, where I though my old adage, "wait and hope long enough
and Microsoft may get around to fixing it themselves" (an adage
adopted because I've never known anyone able to influence them as to
what they fix, or even to influence what they identify as needing
fixing). But it must have been a fluke because it came back and I went
right back to the users groups, thinking that surely someone had
identified the real problem in the 4 months I was missing.

Anyway, my point in all this is to say, based on my experience and
completely non-technical background is that I think this is an XP bug,
and that it is not a program or an add-on or spyware or anything else
that is causing the problem. It's just too generalized for that and
happens under too many circumstances. And I'm sorry that we've all had
to waste so much time searching for fixes to a problem serious enough
to disable our machines, a problem I feel Microsoft should've
addressed a long time ago.

In the meantime, I'll go back to the only long-term solution that
works for me. Walk away from it and come back in a few hours - if I'm
lucky, that will work and I can get a few hours out of it before it
starts again. Try my fix.

Unfortunately computers are complicated and the hardware and software permutations are nearly endless.
You need to get a tool such as Process Explorer:

http://www.microsoft.com/technet/sysinternals/utilities/ProcessExplorer.mspx

so that you can readily identify the offending process that is using all your CPU. Once that is identified that
will be a big help in finding a solution.

Have you done a clean install to see if that fixes it? If so then image the
system to an external hard drive using something like Acronis True Image
Home version 10. Then start to build the system, adding programs and
testing. Make images along the way but save some of the images so you have
something to go back to.

So you're saying that what I see under processes isn't correct?

And will this explain the major differences in power when using the
same program from one day to the next. ? For example, tonite Outlook
is using 100% CPU - if I close it down, no problem, I can surf the
web. But if I try to use Word, Word will send it up to 100% CPU and
basically shut me down. This morning, same programs, no problem, moved
right along, never even approached anywhere near 100%.

Yesterday I was using Outlook, surfing the web intermittently, using
word, had 2 excel spreadsheets open and was doing some advanced photo-
editing in Picture-it (am working on a special project). No problem,
never reached 100% CPU, was humming along. Day before that, same
thing. But 3 days ago, wouldn't wash, 100% CPU no matter what I tried
to do, even with a single program only.

Is this indicative of an offending process?

My problem with that is that the 100% CPU power problem is so erratic,
how do I know when it's gone? I went 4 months without it once. Thanks!

When this happens, open Task Manager to the Processes tab and tell us what
process(es) is showing high CPU consumption and what percentage (e.g.,
SVCHOST.EXE).

Not knowing what you've tried, I'd recommend doing the following to rule out
Automatic Updates being the cause of the problem:

Courtesy of MVP Emeritus Ottmar Freudenberger:

1. First install the newly released 'standalone' version of Windows Update
Agent 3.0, v7.0.6000.374
http://support.microsoft.com/kb/932494

Direct Download links:

x86-based versions of Windows (most users)
http://download.windowsupdate.com/v7/windowsupdate/redist/standalone/windowsupdateagent30-x86.exe

x64-based versions of Windows
http://download.windowsupdate.com/v7/windowsupdate/redist/standalone/windowsupdateagent30-x64.exe

Itanium-based versions of Windows
http://download.windowsupdate.com/v7/windowsupdate/redist/standalone/windowsupdateagent30-ia64.exe

2. Now (re)install this (updated) fix:
http://support.microsoft.com/kb/927891

NB: Windows Update/Automatic Updates started offering 927891 on 22 May-07.
If "Update for Windows XP (KB927891)" is listed in Add/Remove Programs (make
sure Show Updates box is checked), it's already installed. cf.
http://www.microsoft.com/technet/security/advisory/927891.mspx

3. Reboot.

The MS update team believes that this solves all three svchost problems that
folks have been experiencing. See

and http://blogs.technet.com/wsus/archive/2007/04/28/update-on.aspx

It’s important to note that with the MSI fix and the new client installed,
the CPU may still go near 100%, but the system should still be responsive
and not lock up. If another task requires CPU cycles they will be shared,
but if the system is idle, MSI will use the full cycles available. If a
task is running at the same time as MSI, the system may be slightly slower,
but should still be responsive during this time. Key to remember the MSI
fix and the new client address unresponsive or locked systems. CPU spikes
during some scans are expected, machine unresponsiveness is not. If your
watching the process monitor, you will still see 100% CPU during some scans
and this is expected behavior.

Understood. On again, off again problems are hard to diagnose. Then again
if there is something buggered on your system, that may be the way to
eliminate it, and with regular imaging while things are running well you
might be able to intercept it when a particular change triggers it, and
allow you to go back a step to when it was working.

There was a starting point for it. Since you have been living with this for
so long, trying to figure out what it is might not be possible, as might
also be the case with figuring out a cure. It's so much easier to find the
cause / eliminate the problem if it's attacked immediately after initial
onset.

Only you can decide if you're at the point where you want to go this route.
PA Bear gave you a variety of things to try based on recent developments.
Good luck.
