CPU 50% System idle shows 98%

    I have Vista Home premium for 2 years. About a week ago it slowed to a
    point where it may take 5 minutes to respond. Task manager Performance
    shows about 50% CPU usaage but Processes says 98% idle. If I start in
    safe mode Task Manager is the same but I seem to get a little better
    response. I use a free version of AVG.
    This problem seems to show up a lot in Google but each one seems to get
    resolved a different way. I tried some things others did but it has had
    no affect. The last time I started there were about 10 SVCHOST
    processes. I ended a few but nothing changed.
    It takes a long time for one to end because the response is so slow.
    And it gets slower the longer I am up.

    Where do I start to get to the bottom of this?

    Thanks, I will try them this weekend when I get home and will let you
    know how it went. I have to do some work from home starting May 16 so if
    these things do not work I will be reloading Vista.

    I just read them and I have done at least half already based on info I
    googled.
    How do I *::Install the Latest BIOS and Device Drivers. ::*
    How do I know which I need. There probably is some info on it
    somewhere.
    Most performance enhancements will help in general but I would be
    surprised if they resolve my problem since I actually have something
    using the CPU.

    SMBerger,

    If you can give me the brand and model number of your motherboard, o
    model number of your OEM (store bought) computer, I can look up th
    information for you at their website.

    Hi Shawn,
    I bought this desktop from Cyberpower. They replaced the motherboard in
    September '07 and it was different than the one I originally had. Now
    that I think of it, being that it is fairly new am I barking up the
    wrong tree?

    SMBerger,

    If it is still under warranty, then you might check into that option to
    see if they can look at it for you for free.

    You can download this free program called "CPU-Z" that will tell you
    what your "Mainboard" information is. I will need the Manufacturer and
    Model number under Motherboard to look it up.

    This program does not install on your computer. It comes in a ZIP file
    that you just extract all the files on your desktop and run the cpuz.exe
    file.

    'CPUID' (http://www.cpuid.com/cpuz.php)

    Hi Shawn
    It has been a long weekend. Anyway, I decided to reload Vista. The P
    came with a disc that was labeled Vista recovery. I called the compan
    tech line and they told me it reloads Vista and I would lose my ow
    files. Well, they were wrong. I started recovery and it looks like i
    connects to MS to do the recovery. It said it would take a few hours. I
    took a little over 11 hours. First it does some checking, then get
    files then loads and keeps rebooting and eventually it gets done. I
    then tells me that windows will not activate without my typing in th
    Vista product number, which you would thing that would ask for before i
    started. Anyway when yhe desktop came up I had my own stuff still there
    A citrix connection to work which did give me an error message but di
    connect me. And I still had Firefox and few other things. And respons
    was OK but not great. But the kicker is that when I checked tas
    manager it still shows 50% CPU usage. Maybe I just never noticed it
    Does Vista use that much? The performance screen is split. The one o
    the right the graph shows it is all the way up and the one on the lef
    just shows 1 or 2 percent. So in total it is around 50 -52%. But the
    why does processes show 98 percent idle
    I am going to try the list you sent me to see if anything changes. I
    was impossible to try before because it could take 5 to 10 minutes pe
    response
    Thanks again and I will keep you posted

    Do you have a dual core CPU? If yes then Idle is running 98% of the time
    and since it only requires 1 CPU your total CPU usage is 50%.

    SMBerger,

    Take a look in Resource Monitor under the CPU line. It will lis
    everything that is using the CPU and by how much percentage. It may hel
    in finding out what is using so much. What CPU do you have? If it's
    older slower one, then Vista could put a bit of strain on it. 50-52% i
    still a lot though.

    This tutorial will show you how to open the Resoure Monitor if needed.

    Hope this helps,

  11. Hi guys & gals,

    There is another post in this forum "suddenly slow" which also describes
    this problem. I too am experiencing the problem. I am getting the feeling
    it is a windows vista problem probably from an update installed recently.
    somehow we need to get ms involved to resolve this issue. we can't all be
    using the same hardware or have the same program installed that would be
    common to cause this issue surely

    Well if you google vista cpu you will find lots of similar issues.
    tried some of the things that helped others and it did nothing for me
    In some instances people had just loaded something new but in many case
    it turned out to be something in Vista. But the problem is how to fin
    it so that you can shut it off. So I will try what Shawn suggests an
    see if I can pin it down at least for my PC. You should try it for your
    as well and see what comes up

    Hi Shawn. I got through a few steps from your list last night
    What is-Click on *Continue *(UAC), *Yes*, and then *OK* when prompted.
    never got that

    So far no improvement and in fact it seems to be getting slower. If
    move a panel it gets recreated over and over from the place I starte
    till where I place it. I will continue on with the list tonight
    Thanks for you efforts

    The "Continue" is for the UAC (User Account Control) Prompt. Unless yo
    have UAC turned off or elevated the administrator account, it wil
    usually pop-up after you click on the "Resource Monitor" button in Tas
    Manager asking your permission to "Continue" before running it

    Your system may be getting hung up waiting for disk transfers.
    How much memory on your system?
    Do you have DMA disk transfers enabled?
    How much disk space do you have allocated to your paging file?

    Use Help for
    DMA
    or for
    Paging
    Paging is also known as virtual memory.

    SvcHost is the host task for your system services most of which never run
    after first being started unless they are needed.

    SURPRISE My cpu usage is down to zero and I don't know why. Here is
    clue. I caled the tech line where I bought this pc and he wanted t
    check the memory. I did not have time and told him I would call bac
    later. Before I caled him I shut down the system and removed the back s
    I would have access to the motherboard. I called and the line was bus
    so I turned the PC back on and CPU usage was zero. What does that te
    you. Is there a hardware problem waiting to happen again

    SMBerger,

    I'm not sure why it would suddenly go back to normal for no apparen
    reason, but I'm glad that it is working normally for you now. To b
    safe, I would keep good backups just in case.

  20. Hi Fello Forum Members,

    As previously listed I have the same problem. I have just concluded a call
    with MS tech support here in Oz and found that the Computer Associates CA
    AntiVirus software I am running may well have been the culprit. Apharently
    an update to that software clashes with an update from MS. The tech support
    people have "snoozed" CA to determin if this is the real problem.

    Will let you know how I go over the next day or so if you want.

    Good luck with your problems

    Regards
    RF
