Windows 7 suddenly slow and System Idle process CPU utilization a concern

Almost overnight, my Sony Vaio with Windows 7 (bought in 2010) has worked incredibly slow.  I tried to update the computer with the automatic updates of Windows and the Service Pack 1 could not install many times.  So, I installed the system update readiness tool.  Then I tried to install the SP again and it worked (I was also able to install SP2 and other updates at this point).  But, these downloads and installations took longer than they should have and my computer continues to lag when I'm trying to do something.  Norton AntiVirus found no problem.  I've only used about 20 percent of the memory.  System Idle Process is using high CPU, even when I try to use other programs such as IE and Google Chrome.  The computer fans work diligently as if the computer tries to run, but everything is going so slow that the computer is almost useless.

The computer is almost three years old, but did not have something else installed Norton because I bought the new computer.  It has been used daily for almost three years without problem.  I do a lot but check Windows Live Mail, and then type the documents in Word format - literally that's all; no other programs, games, etc.  However, I have an error code a few months back: 'Not authentic Windows, Build 7600.'  In response to the error, I got my product key and verified the program and to use new Windows 7.
Anyone know why the system idle process continues to consume so much CPU even when I try to open a web browser?  Even when the computer is inactive, the fans are running full speed and the computer becomes warm to the touch.  It seems that no matter what the computer is doing, it is lagging behind and struggling.  Even if I just want to open the start menu, it takes a few seconds for the computer to respond.
Thank you!

It is not dust but the crapware that you must get rid.  The first suspect is Norton, which is a terrible software that slows down terribly computers.  Get rid of Norton and install Comodo Internet Security instead.  Make sure that when you get rid of the plague of Norton, you get the Norton Removal tool and run twice.  Also, make sure that manually enter you your folder program files and delete all Norton and Symantec files and use a program like Malwarebytes file Assassin to get rid of the persistent process who do not want to delete.

Then use CCleaner (and ONLY CCleaner - do not download or install any other system cleaners or registry mechanic) for cleaning your system and use Revo Uninstaller to remove any extra crapware that is installed on your machine.  Be sure to remove any software from Apple and get rid of all Windows Live software.

Finally, you'll want to disable several Windows processes that eat up RAM unnecessarily.  These include Sync Windows, Windows Defender and Windows Action Center.

Follow all the advice and you should find that your computer is running a lot faster.

  • Use high CPU (35% average) while System Idle process CPU about 98% but frustrated by "[name of the prog] has stopped working".

    Hello

    I am trying to help someone with a laptop HP model g6-1202sa (Windows 7 Home Premium 64 - bit, another record at the end of the post).

    I think that Windows is now updated and drivers, but the problem remains also.

    The laptop has the symptoms mentioned in the title I found the Manager tasks.  Laptop fan is on a large part of the time, and the owner says that, during the execution of something more intensive than Skype for example of internet browsing, they get a warning from Norton on high CPU. Resource monitor shows that system interrupts are on average about 31% CPU.

    The results, I found the task manager has led to some research on Google, which in turn led me to want to run adksetup.exe (Windows Assessment and Deployment Kit) in the hope of discovering if a particular driver is causing the problem. (Various threads on the internet point to what is the way to go).

    However, after downloading adksetup.exe, when I try to launch it I get the initial screen of Toolbox and then 'assessment of Windows and the deployment for Windows 8.1 Kit has stopped working ". (Verification of the solution finally gives the only option to "Close the program").  Similarly, I have now discovered that if I try to look at the properties of the computer, i.e. start > right click on computer > left click on properties, I get "Windows Explorer has stopped working". Do more research on Google I find sometimes I get "Internet Explorer has stopped working" sometimes (Chrome is ok).  More out of curiosity than anything specific I ran AMD VISION Engine Control Center after right click on the desktop and ended with 'Catalyst Control Center; The host Application has stopped working".

    So before going any further, does anyone have any ideas what's happening?   I do not understand the problems 'has stopped working"in safe mode, but the high utilization of the processor with System Idle Process around 98% is still there.  It appears so that I can run adksetup.exe in safe mode while this would be the way to proceed and continue to try to tackle the problem of CPU?

    For the record, some of the things I've done along the way include update of Windows, updating drivers, running the file system (no violation of integrity) checker, a regular chkdsk ("CHKDSK discovered free space marked allocated in the master file table (MFT) bitmap. Correcting errors in the volume bitmap. Windows has made corrections to the file system").  Swapped the only module memory 4GB 2 x 1 GB modules I had to hang out, all the symptoms remained 4 GB then reinstalled.

    As you can see there are at least a dozen of them which are probably related to the high utilization of the processor.

    I think it might be a good idea to download a video of this really irritating problem.  I'll see what I can do.  I had this problem for about 2 years.   Furthermore, I'm typing this on my Windows 7 netbook because my Windows XP desktop computer has been in "system idle process" for about an hour and I can't use it for anything.  I tried to stop (via the power button since I can't use start - stop) and reboot, but it just goes back to system idle process until he is good and ready to stop it and I would like to have the control again.

  • Is it possible to see what is running in the system idle process?

    Too often, my laptop computer Windows 7 system slows down to a crawl. Lambasts the drive. And Windows 7 will be smart enough to know that things are bad, but not smart enough to know exactly which slows down things. It is simply asking if I want to use an interface that uses fewer resources.

    If I look at the screen in a program called Process Explorer, it is said that most of the cpu is used by a process called the system idle process. But you cannot stop this process. I need more information. What is past in the idle system process that slows down my system to a crawl, alarming even Windows 7 and stolen my hard drive - it's what I want to know.

  • The system idle process is always about 99%

    Hello

    I noticed that the system idle process in the Task Manager is still 99%. What is a natural process or that this indicates a virus in the background or something? I also noticed that my laptop runs slower than expected performance.

    I have Windows XP Pro installed in the laptop.

    Please someone with an answer to this question, the answer!

    Hey Taha,

    Your the system idle process will sometimes show high CPU usage, but this should not be for a long period of time. Windows XP runs its own maintenance tasks periodically (usually when the system is not busy), but these should appear as frequently or for a long period.

    I would recommend running a scan for spyware on your system to make sure that there is nothing of causing your slow performance.

  • Why the system idle process makes my desk fan light constantly

    Why the system idle process makes my desk fan light constantly

    The system idle process has nothing to do with your fan coming.  Your computer constantly monitors the temperature of your CPU and if this temperature is too hot, then the fans move on to high speed.  You can use the freeware 'CoreTemp' program to display the temperature of your CPU, if you want.  Temperature rises usually when the computer is under heavy CPU load but the usual cause of high speed switching fans is an accumulation of dust inside the computer and close the CPU fan.  Open your case and clean the dust.  A can of compressed air makes quick work of it.

  • Use of the CPU 50% but System Idle process 98%

    Windows XP SP3 on an AMD x 2 processor.

    One of the nuclei seems to run at 90-100% depending on the Performance graph.  The status bar downstairs, explains the 50% CPU usage.  But when I look at a process it shows the system idle process 96-99%.

    Network traffic is negligible.

    Any suggestions on how to find out what each of my CPU would be appreciated

    Check with Sysinternals Process Explorer. I wonder if you will notice interruptions or DPC having a high amount of CPU usage (which the Task Manager will be assigned to the System Idle Process).

  • understand the system idle process

    The Task Manager process often indicates "System Idle process" in courses running almost continuously and the disc access light stays on for an extended period. What is going on? And why not a title like "System idle" are located in the help files or administrative tools/Services?

  • Should the System Idle process percentage turn all the time in the order of 90%?

    The System Idle process percentage seems to run constantly in the order of 90% in the task Mgr it can not ends the process either, I read what is normal, or there are problems with registry, or has something to do with Norton Anti Virus so what is the right answer here?

    It's normal. It's just a percentage of time processor. If it was really low, it means that your processor is overworked all the time and would not be a good thing.

  • How to end the system idle process

    How to end the system idle process
    ... "it is to consume my whole CPU.

    system:
    HP pavilion g4 series
    Intel core i5

    No it's not! Maybe someone else can give a better explanation, but the way I understand it is that when your system is idle, the system shows 100% idle process or nearby and it is because it has no applications or programs that run, but as soon as you open a program or run an application, and it requires CPU resources say between 1 and 4%, you will see the system idle drop in numbers, which shows the amount of the resources required by the program or open application.

    So I believe that everything that is, show processor resources available to a given point in time.

    Now, a virus can attack the process and change his behavior? I don't know, but if you suspect a malware attack, run complete scans of your system just to be sure.

    Good luck.

  • What is the system idle process, and do I need? Its killing me!

    Can I remove it. Can I repair this hungry beast. It gets running in background and everything grinds down to a slow crawl. I check the task mgr and at the bottom of the list is the beast. Using 98% on the list, but showing the use of 27% on the dialog box. XP running on the laptop Dell D610. I've seen other years download program to show which processes are working but I'm not sure what to do with this info. I'm not as well that I would that be.

    Thank you

    System Idle is 100% CPU capacity less any percentage is used. It is not the hungry beast, you think it is!

    There is Nothing to "remove, disable or close. "System Idle.

    just the name for the system when it does not
    whatever it is. It is there just to make the total adding up to 100%.

    If you see reading of 70 to 99%, so that means you actually use
    only 1% to 30%. This is quite normal. Nothing to worry about.
