High CPU in Windows 7 between 80 to 100% usage

• High CPU use/Slow Performance after you install the updates of Windows

  I run Vista Business 32-bit.

  After you install many Windows updates in the last few days, I've known very slow performance after the system worked for a while. Resource monitor shows 70-100% CPU usage, even when you run all the apps (that I know of). This makes everyhting grind to a halt, same trip that the mouse jerky movements. I ran several complete system with McAfee anti virus scans and not found problems (using the latest software). The detail showed the so-called ", PID4 NT kernel and system" using 18% avialable CPU capacity, but this process is not always shown to use much more capacity when the slow performance occurs. Nothing else don't use much capacity CPU, I see.

  More recently, the capacity of the CPU became crazy, jumping from zero to 100% usage in a back a suite oscillation. When I shut down and restart, performance improves, but erodes little by little over time.

  Is this a sign of a virus, or is it a problem with the recent Windows updates or some kind of conflict with my software such as McAfee? How do I tell me what to do? Anyone else have this problem with the recent Windows updates?

  Help!  Thank you!!

  McAfee applications (and Norton) are known for not not upgrade (or uninstalling) itself.

  1. download the McAfee Consumer Product Removal, save it to your desktop tool: http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe

  2. close all open applications (that is, anything with an icon on the taskbar).

  3. now run this triple McAfee fix: http://service.mcafee.com/FAQDocument.aspx?id=TS100507

  NOTE: Step #2 McAfee fix run the removal tool, you have already downloaded in my step #1 above.

  4 IMPORTANT! => After the reinstallation of the McAfee application (step #3 of the McAfee fix), manually & repeatedly updated the McAfee application, until you get a prompt "no update more".

  5. open Internet Explorer (only) to http://support.microsoft.com/kb/923737 & run the difficulty.

  6. OPTIONAL: For good measure, pen also Internet Explore (only) to http://support.microsoft.com/kb/971058 & race that secure it in DEFAULT and modes and AGGRESSIVE. [1]

• High CPU consumption (always between 12 and 30%)

  I am running Firefox 9.0.1 for Mac. Until the upgrade to version 9.0.1 I had no use of high CPU problems... I've now must constantly between 12% and 30% of CPU and up to sometimes use much further than that, which really slows down my Mac to a point where I have to kill Firefox to use other applications.

  I have a new Mac mini with fast CPU and 8 GB of RAM.

  I tried to reinstall and also to disable the 4 Add-ons I have installed. After a new installation and all 4 disabled add-ons, I see exactly the same problem even with one tab open to google.com

  Any help from the community is very much appreciated.

  Thanks in advance...

  I've upgraded to Firefox 10 and this issue is now resolved.

• Windows 7 update - slow download, svchost high CPU usage

  I have a problem downloading by using the Windows Update application. This problem started after January 2016.  In the past, the request of update seems to work without the use of the svchost high CPU and with a reasonable download time.  There is usually a delay until the download has started, but then they ended quickly.

  I have 4 computers: 3 running Windows 7 Pro (CPU - Intel dual, i5 & i7) and 1 running Windows 7 Home (Intel i3).  If the problem is not related to the CPU hardware as best I can tell.

  My update setting is 'check for updates but let me download and install ".

  The Windows Update process includes 3 steps:
  1. identify the important and recommended updates for your computer.
  2. the selection and download updates.
  3. the creation of the restore point and of the installation, the selected updates.

  My problem is step 2, download the selected updates.  This happens on all 4 systems, and I do not expect a download to be this CPU load.  The download time is too long on all systems 4.

  My online search for answers has been frustrating, but several posts said search for viruses, malware and Trojans.  I ran Malwarebytes (free), Windows Defender, Norton Security and ESET (online) on systems and no objects are found.

  My most recent experience involved my Lenovo 7847 system (Intel dual core). Monday, May 23, I checked the updates and there were 15 updates important and 3 optional updates listed.

  After reviewing the updates, I chose the 15 updates and started the download process.  The svchost.exe that is associated with the update happened to 45-60% CPU usage, update status showed no size or % finished and the task manager - network or explore the process did not show any activity download for a long time.

  Finally, after about an hour, the update showed the download size and the % downloaded.  Svchost usage remains high during the time of whole download.  Once the download is complete, the restore point was created and updates have been installed, who also took some time (but it would be I/O CPU & Drive dependent).

  The download status has not changed during most of the time that the download process is running.  The Task Manager and process explore both show very little network activity up to that very near the end of the download procedure. There is therefore no real indication that the process is blocked or just turn very slowly.   It almost seems that the Microsoft servers are overloaded, they delay the download for some reason, or the process svchost and sub-process fail to create good handshake with the server for download.

  My Questions:

  1. Why is svchost usage so high when nothing seems to happen?
  2. Why does take an hour or more to download the updates?  These aren't the huge file sizes, and this attempt to update was almost 2 weeks after Patch Tuesday, then Microsoft servers should not be overloaded.
  3. Why is the situation unchanged for so long during the download process?
  4. most important, what can I do to change this situation?
   
  Thanks in advance for your help.

  My 'update problem' seems to have changed.  Checking updates takes a lot of CPU resources and a lot of time.

  We will leave well enough alone for now. [It took 3-4 hours for MU download/install updates of June on my Win7 boxes].

  But please bookmark this thread. If the behavior persists in July - and especially in August, respond to this thread instead of starting a new. Good luck!

• Windows 7 high CPU wuauserv

  I was just going about my day when I noticed abnormally high CPU usage, something has been using 12%.

  and he was stuck on checking for updates, so I've restarted and my pc this time stop wuauserv always does the same thing but

  This time, he said no update necessary so I tried to install optional updates not important to see if it will address the problem

  but it was stuck at 0% and it's premiering in atm im do not know what to do any help would be greatly appreciated thanks.

• Windows Update causes high CPU AND not let me install Windows 10

  Windows 7 update has several issues:

  1 Windows Update Service causes the CPU usage high - CPU usually works 50% or more with a single SVCHOST.exe running.  I click with the right button on the SVCHOST entry in Task Manager-processes and saw all the services that SVCHOST is still running.  One at a time, I stopped and restarted them.  Finally, when I stopped the Windows Update service, the cpu immediately fell to almost nothing.  I rebooted and tested several times, and each time, it was Windows Update service that was causing the high CPU.

  2. Windows 10 Upgrade Advisor says I could upgrade to Windows 10, and get the icon Windows 10 is in the toolbar.  But it has failed to install several times.  Now, after stopping and restarting the service of updating (and I checked, it is started), the window get Windows 10 rises, is empty and goes.

  3. I ran the Update Diagnostic and got 1 error:

  Windows Update error 0 x 80070003(2016-04-04-T-04_56_09P)

  the Details of the Diag Windows Update window said:

  RootCause: RC-DataStore

  Error code: 0 x 80070003

  4. I tried to launch the 'Fixit' for update, but it did nothing.

  5. I tried to update Windows Update WindowsUpdateAgent30 - x 64 .exe Agent,

  but it fails with this message:

  "Windows Update Agent Installer has met a fatal error"

  6. when I try to start Windows Update-check for updates, it displays the dialog box "check for Updates" and activity indicator green runs and runs and runs for more than 10 minutes but nothing happens.  And when I check the view update history, it shows no updates, even though I know that I've run a LOT of updates in recent years.

  7. I thought to reinstall Windows 7.  I went to download from Microsoft, and when repair installation it activated my key it says that it wasn't a retail version, so check with the supplier (in this case HP).  I checked with HP and they said that this machine was is no longer supported.

  8. on the way I've renamed the folder C:\Windows\SoftwareDistribution-Windows SDOLD, force it to create a new (probably why it does not find the old updates).  IT did not help.

  So it seems to me this machine is expandable to 10 Windows (it meets the specifications and the Advisor to update Windows-10 said yes and installed the toolbar).  But something is wrong, probably with Windows Updater, and now nothing will be update or upgrade.  And I can't get a new copy of Windows 7.

  So, any thoughts?  I'm out of ideas.

• Windows.exe gobbling up memory and CPU often CPU ranges between 50 and 100%.

  Hello

  My PC recently turned very, very slowly and often unresponsive.  When I bring up the Task Manager, on the processes tab, I see that Windows.exe uses as much as 1 million K of memory and often the CPU ranges between 50 and 100%.  What is happening while no application works.  I have also noticed that in the Task Manager, there are two processes with the name of the image of windows.exe and consuming all the power and memory has no user name.  When I try to end the process on this one it still won't let me and a message appears saying that I don't have permission to do this, or something to that effect.  I am however able to stop other processes including the windows.exe with my username process.  The cases where it allows me to stop the process, performance improves, but given a little time, again with nothing running, it starts again. Thinking it was a virus, I missed the live update on Norton and performed a full scan, but nothing found.   I also tried Windows defender, but in vain.  Any help on this problem is greatly appreciated.

  Thank you

• Portege R700 - high CPU fan noise

  Hello

  I own the Canadian version of the Portege R700, called Tecra R700 (PT319C-00E002).
  The CPU fan always runs between 43 percent and 51 percent (regardless of the mode of selected frequency), which makes the noisy computer - too noisy to be used comfortably, too noisy to be used at meetings of air-conditioned silent.

  The fan seems to be controlled by the BIOS, as well as applications such as SpeedFan are unnecessary. Is there a way to fix this?

  Kind regards.

  Hi dernierrecours,

  > CPU fan always running between 43 percent and 51 percent (regardless of the selected frequency mode)
  This means that the fan runs always at the same level regardless cooling method that you can choose in Windows power management?

  Well, have you tried updating the BIOS? The latest version is installed?

• Satellite P300-212 - system causes the periodic high CPU load

  Windows Vista Edition Home Premium (OEM) on the Toshiba Satellite P300-212

  Even on a system Windows freshly installed (from recovery DVDs), the system process (PID 4, NT Kernel & System) causes on a regular basis (every five minutes) a CPU load high for a few seconds, during which the system hangs, not even the mouse pointer can be moved.
  Sysinternals Process Explorer identifies the thread of high load as "ntkrnlpa.exe! ExfTryAcquirePushLockShared + 0 x 15 2 "with the thread ID 20 or 24.

  Does anyone have an explanation for this behavior or a solution to the problem?

  Hey,.

  If you have installed Windows recovery disk Toshiba but still high CPU usage? Hmm that's strange because this image is tested by Toshiba

  Have you installed or uninstalled any software or tools?
  I uninstall the current antivirus and disable some start up programs you n t need in msconfig. Usually, this should work.

• Tecra M2 - stop hard on high CPU (turns off with no BSOD)

  Experienced stops consistent when the CPU is running at full during a little while.
  -J' mean 'stops' complete power cut with no blue screen of death where all is lost and the computer must be restarted manually.
  -by "high CPU", I mean when the processor locks to full use such that when you insert a column in a big Excel sheet with errors or if you want a large number of files and you open a video from the network or when you run a registry scan and antivirus analysis at the same time.

  The problem took place regularly for a few months and I can now make a case with greater predictability. Using the hardware monitor suite 'Everest', it seems that the problem occurs when the temperature of the CPU is located at 99 for more than a minute or more.

  This happens with some, but never when batteries run - then attempts to force the error, it will not be stopped if the power cable is released just before the drop point.

  In the cases of the problem, it seems to be a small error message appearing only a fraction of a second before the death of the computer.

  Each reference forum and help that I read would suggest the problem is related material and that the chip or the motherboard is overheating and need replacement. While the laptop is almost 18 months old, I bought a new ' everything except the screen and HDD "earlier this year, and was not prepared to accept the explanation without more tests.

  Kantonix Linux works very well and the CD starts seems to tax the processor as much as the same events that kill for me under XP.

  A few weeks back, I installed Windows XP on a second HARD drive in the Bay of hotswappable and noted the installation seems to work pretty hot computer and he died during the process. It has experienced no difficulties for while but, a few days after moving the HARD drive reinstalled in the primary position and after you have reinstalled a lot a lot of applications, the error started happening again.

  Last night I caught a few fractions of a second before the death, the pulling power and stop the process and allow me to see the error message (as mentioned above):

  -first message came from "TOSHIBA Power Saver" saying "a fatal error occurred at x 06" (not sure about the last bit) ".

  -second message was "THotkey.exe' saying 'could not load powrprof.dll.

  -monitoring of several hundred cases of the second message.

  Because of the error messages, I was not able to get a print screen.

  Solutions or even on ideas that would be very appreciated!

  Hello

  According to your explanations and the information in your ad, I think that the problem is related to the software.
  You wrote something about energy saving. This Toshiba utility controls the speed of the CPU and the use of cooling modules.
  I think that this request could be responsible by the judgments. Try reinstalling this utility.
  In addition, check the configuration of the unique power plans. If you work only with battery energy saver using another mode of power supply as working on AC.
  I think you could check these consumption patterns and configure it.

  Verification of the cooling module is also not a bad idea. Maybe fans cannot work properly because of the dust and debris inside the books.
  I use the vacuum cleaner to clean the fans. CA? s an easy way to make it free of dust.
  But if you get it, you must be careful.

• Qosmio F60 - alert constantly high CPU usage

  Hello

  About 12 months ago, I bought a Toshiba Qosmio F60 computer laptop 6 GB.

  When exploring using games, facebook etc, I am constantly alert of my Norton informing that there is high CPU usage.

  I have asked around locally and advised to delete Norton because this may be the problem. I'm not eager to do what my subscription is still valid.

  I also learned the other day that this is a common problem with laptops Toshiba using 'Explorer' and that I should use "Mozilla Firefox" instead which would correct the problem.

  I am trying to arrange this.

  Can you please indicate if it is a regular problem with Toshiba laptops and reviewing the options above to try to address this problem.

  It doesn't really seem to my computer, it goes more slowly and when in the Manager tasks, it is constantly fluctuating between 5 and 35%

  I look forward for your reply.

  Thank you

  Hello

  This isn't a problem laptop buddy
  Norton AntiVirus is a good antivirus program, but it uses a lot of resources and my experience locks the CPU.

  I removed this antivirus software and now I m using the avast and Avira Antivir free Antivirus software. Both are freeware software.

  But I still use Internet Explorer. Of course, I also installed the firefox and chrome. All these three browsers are great.

• Satellite A 110 is suspended due to high CPU temperatures

  Hello

  My computer is hung up on me while running certain applications (such as Dreamweaver CS3) or other situations in which work the CPU at maximum performance. I suspect that the reason is high CPU temperatures and indeed download several CPU, monitor applications (like thermal analyst intel) my average CPU temperature is around 61 degrees (Celsius), and before the computer hangs (instantly - just completely stop lose power), it reaches very high and not necessairly after working for a long time.

  My questions:
  1. is this a known problem with this model?
  2. is there anything I can do to limit this problem and avoid data loss?

  Thanks in advance,

  URI

  I think you will need to contact the ASP in your country for assistance.
  In your case maybe the cooling module may not work correctly. Probably the thermal grease that is placed between the CPU and the cooling module must be renewed.

  All these things need to be clarified.
  So call it the ASP.

• DAQmx read results 2 ms/s in high CPU usage

  I have an application that reads the 32 channels of 2 ms/s analog input signals, at the same time. The actual hardware will be: SMU-8135 Win7, chassis SMU-1071, 2 x SMU-6368 (16 channels). The SMU-two 6368 will provide 32 channels data acquisition.

  I don't have the material at the moment, but I've been estimate the processor on the alternative configurations needs, because I have concerns about the use of the CPU to data acquisition high speed. Two alternative configurations are:

  (1) SMU-8133 (quad core) WinXP, SMU-1062 q, PXI-6133.

  (2) PXI-8106 (dual-core) WinXP, PXI-6133, PXI-1042.

  Note: PXI-6133 supports high speed HAVE 2 ms/s, at the same time.

  I wrote a simple continuous data acquisition software to allow me to compare the CPU usage. The sample rate and the number of channels are configurable. What I found is:

  (1) at low sampling frequency, for example 100 kech. / s, the CPU usage is minimal on both configurations (bicoeur or image), regardless of the number of channels is 1 or 8. The reading of the CPU was about 1-4%

  (2) at high sampling frequency, for example 2 ms/s, what is the number of channels used, either 1 or 8, the CPU utilization was 50% for dual core and 25% for the quad core, IE. a full core has been fully utilized.

  (3) the passage of the low use of the processor (<5%) to="" high="" cpu="" usage="" (="">45%) increases when the sampling rate is rather steep and shows interesting channel-dependence (note the following has been achieved with a PXI-8106 controller, dual-core).

  • @1 channel, it happened between 950 to 970 k
  • @2 channels, it happened between 470 to 480 k
  • @4 channels, it happened between 230 to 240 k,.
  • @8 channels, it happened between 120 to 130 k.

  This model reminds me of buffer length related question but I double checked a sufficient length of the buffer was used. He suggested also, surprising a few traffic jams occurred when the amount of data increases up to certain level.

  My question is, is this a problem with this particular card (PXI-6133) or driver DAQmx (9.5.5f4). How the problem is when I'm doing an acquisition of 32 channels?

  For your information, I have attached the benchmarking software.

  Thank you!

  Donghui Yin

  I followed this example code (see link below) and used based on events DAQmx, now the excessive CPU utilization problem has been resolved. Playback from the CPU is now less than 10 percent, while it could be 50% (in the case of dual-core) or 25% (case of hearts) at the same sample rate and number of channels.
