CPU usage 100%


G

Guest

I checked my indexing and it says 507 items and completed. I checked my task
manager and it shows my CPU usage as 90% or greater, average is 93% but
generally hits 100%.

I've done adware searching and had 102 items and removed them. still no help

I've turned off unneeded services like auto updates with no help against my
CPU usage.

I've indiscriminately combed through my task manager processes and nothing
hits the amount of usage that would raise an eye brow as to being the culprit.

is this a common thing? any help would be great. maybe there's something I'm
missing or haven't thought of.

In Windows XP I would recommend Process Explorer. I have not used it
in Vista but the latest version is available for use with Vista.

For further information about Process Explorer see here:
http://www.microsoft.com/technet/sysinternals/SystemInformation/ProcessExplorer.mspx

To ascertain which service is causing the problem select the process
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://majorgeeks.com/page.php?id=12

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.

Thanks first and foremost Gerry, I downloaded that procexp and it says that the 90% CPU usage is due to hardware interrupts. well the battle is half over. so now how do I go about messing to get the interrupts fixed?

that will end the entire war then Gerry.

1,000,000 thanks

You've gone off on a tangent. The idea was to identify the particular
process generating the high CPU usage. Do this and tell us the Command
Line of the Process. If you right click on the Process and select
Services it will name the Services using the Process.

You may need to Add Columns. To do this select View, Select Columns.
Try checking Process, PID, Company Name, Version, Window Status, and
Command Line.

OK Gerry I think I made some progress. this issue I'm having falls under the
system idle process/hardware interrupts tree. there was no 'services on
right-mouseclick menu.

It must be generic as it has no company name listed under company name. this
freaks me out. it is using average 85-95% CPU usage. I'm serious and this is
no tangent.

now, I've checked all my hardware for conflicts, nothing.

I am well aware that this can be driver issue but we need to know the
process first. At least that is the way I see it.

If System Idle is running constantly at approaching 100% you have no
problem. System Idle is 100% less the sum of all the running
processes. Thus if System Idle is 95% your processes are only using 5%
of capacity.

Open the Task Manager and click the "Show processes from all users" button
at the bottom of that dialog. Look in the list and see which process, in the
Image Name column, is using the 90+ in the CPU column.

OK Ronnie, I checked. it appears that the SYSTEM(kernel) and SYSTEM IDLE
Process are tag teaming the CPU time the most. sometimes SYS IDLE is 40% and
SYSTEM 20% but both are rocking.

But something Else I found out;
I have 13 svchost.exe running at the same time.
6 running on SYSTEM
3 running NETWORK
4 running LOCAL
Why so many? I've never had so many svchost.exe files running at one time.
could this be the problem?

The System 20% might be problematic, if this is constant, you might want to
employ the Process Explorer (which has already been discussed here) to track
down what is using this process.

The System Idle Process is not a problem since this simply shows how much of
the CPU resources are idle and available for programs to use. In other words
this process shows how much of the CPU resources are NOT being used.

The svchost processes are normal. This is the Service Host module and it
enables all of the many Vista Services to run. In Process Explorer, look on
the left side module tree for svchost.exe. Hover the mouse over each
instance of svchost.exe and an information box will pop up showing which
services each instance is hosting.

To sum things up, you appear to be running fairly well, except for the 20%
CPU, System process. (If this is running consistently, like I mentioned
earlier)

You might also want to refer to the following article on Vista Services.

Then I offer this probability. My Graphiccard driver. they are ATI "Beta"
RTM drivers.

I've heard of folks here who have issues with their graphiccards.

I called Compaq, my system maker and they told me that for $65 i can get 6
motnhs support to include drivers for my system.

hmm sounds like a fishy thing to me. I'm still under warranty and they can
just as well post the drivers on their website for me to download.

thanks Ron

I'll let you know what happens here when drivers for my PC are released.

That's a good possibility.

You might want to test this by turning off all the advanced graphic features
just to see if the System load is reduced.

Here's something Ronnie, looked at my physical memory
total:2045
Cached:1631
Free:4

kernel memory
Total:105
Paged:72
Nonpaged:32

CPU usage90%
CPU usage history is way up at the top

this advanced graphics you mention, are you reffering to the bells and
whistles? like Aero glass interface?

Ronnie,
As well, I checked my wifes, XP system and she has a system idle of 99%

CPU usage is average 2% during a 15 second time

My Vista Business system is

all over the place but average SYSTEM:bounces from 8% to 21% for a 15 sec test
System Idle:bounces as well, 58, 78 84%

this is strange because my mouse lags(stops shortly then moves) and web
browser takes awhile to load. FireFox 2.0

My wifes Kernel is calm and casual mine is a freakin' crack addict.

Like I said, try turning off the graphic features. Open Control
Panel/Performance Information and Features. On the left menu, click Advanced
Tools and then "Adjust the appearance and Performance of Windows."

Select the "Adjust for best performance" radio button. Apply/OK. Check to
see if this makes a difference in the CPU load.

Some other things you can check are the installed anti-virus program to see
how often it is set to scan. Also, what programs are running in the
background and what programs are set to start at boot time.

Go to Start/Run and type msconfig and click OK. Select the Start Up Tab
to see a list of these programs.

You haven't mentioned exactly what it is your trying to track down here? Are
you having problems running programs or games or???

If so, give us a brief over view of your system like CPU speed, installed
RAM, Graphics memory, etc.

Chris, what is your CPU speed speed and how many mb's on RAM do you have? The
CPU that you have could be the problem.

Hi,

I'm running the 32bit Vista Business edition and also experiencing similar
issues. My CPU doesn't constantly run at 100% though it can run like that for
quite some time (sometimes up to 20 minutes) before settling again. After
installing Process Explorer I've discovered that 3 .exe's are periodically
becoming unstable and start behaving erratically.

The processes are as follows:

SearchIndexer.exe
SearchFilterHost.exe
SearchProtocolHost.exe

My system, nothing OC'd (If it helps)

AMD64 3500+(skt939)
DFI Infinity NF4 SLI
2x512 Corsair XMS DDR400
256MB Asus 7600GT
Creative Audigy SE
250GB Maxtor SataII HDD

And I'm experiencing it too. But its only in some cases it appears.

If I start the fileexplorer on the quickstart, that opens in "My Documents"
folder, it does not use any CPU resources.

BUT if I hit [Winkey] + [E] the explorer opens up, with the focus on
"Computer". And then it hogs the CPU untill I shut down the explorer, OR
untill I dive down into the file system somewhere. Then it no longer uses any
noticeable CPU cycles. If I browse back to the "computer" it does not resume
hogging my precious cpu cycles.

It doesnt matter if I'm running classic file explorer settings, or If im
using "run explorer in a separate process" or not. Turning off the Desktop
management service also has no influence on the issue.

This smells like a bug doesnt it?

I'm running Vista Ultimate on a HP NC8430 laptop with a 2.0 Ghz Core2duo and
2 GB RAM. System has a Vista rating of 4.2.

And it's pretty much a vanilla install of Vista.
