    Using Task Manager

    I am a longtime computer user and generally am recognized as the "go-to" person at work and among my friends for computer problems. So, it embarrasses me to have to ask this...

    I have been having a problem with my laptop, a Toshiba Satellite C-55A. 4 GB RAM and a 500 GB HD. Windows 8.1 and I keep it updated. It is about 1 1/2 years old.

    For a while, 6-9 months, it will slow down, mostly in the middle of the day but occasionally at other times. I thought it was a problem with Flash, it kept crashing when I was using Chrome. I switched over to IE11 and it worked better for a while, and I am not getting the Flash crashes but it is still slowing down.

    Here is the embarrassing part, I really don't know how to interpret what Task Manager is telling me. I have started keeping Task Manager open and checking it when it slows down. Quite often it shows (looking at the Processes Tab) Disk at 100%, CPU and Memory higher than 75%. Network generally stays at 0. I have sorted the columns to show what is using the resources and it is usually Internet Explorer or Service Host at the top of the list.

    Typically, I have the running programs that I have open, are IE11 with 8-12 tabs, Windows Mail, File Explorer (1-3 windows open), Word or Excel and Evernote. I don't think that is excessive.

    I also wondered if I have any Tasks that might be running. I looked at the Task Scheduler and I have 62 scheduled tasks. Some I understand, some I don't. I don't think I set up any of them. I have been keeping Task Scheduler open and when the system slows down, I look to see if anything is running, and it isn't.

    Any suggestions on what I should look for that is causing my disk and CPU to be running so high? I'm just not sure what to check. Thank you for any help.

    Nothing to be embarrased about...there is always something to learn.

    You're looking in the right place to start troublehshooting performance issues. There are lots of tips and tricks for using Task Manager available, this one is a good starter...

    http://blogs.windows.com/bloggingwin...ager-in-depth/

    It is not uncommon to see a process using 100% CPU for a short period of time...in fact, it's desirable in cases where a process needs to do something quickly, such as start up a browser.

    Memory may also spike for short durations if, for example, a process is loading something from disk into memory.

    I think the key here is available CPU and memory when the slowdows start...what is left for other applications when everything is running, and something new tries to start, such as an update to your AV definitions.

    The AV update in and of itself may not use a lot of resources, but if there is little available free CPU cycles or available memory, it will struggle to run, and in turn will slow everything else down.

    I would watch for that, and also consider running a System Health Report to see what the overall situation is on your system...

    To add, the only process that usually is a high percentage is System Idle Process, means the CPU is not doing much at that time.

    If you're seeing high disk and memory at the same time, Windows may be swapping programs to disk - swap file / page file - to make room for other programs. As your disk is generally the slowest part of the system it make the computer slow. Try closing a couple of programs you don't need to see if that fixes the problem.

    cheers, Paul

    Hi Guys,

    I appreciate the help. I did go to the Performance Monitor and ran the diagnostic. The only thing it showed negatively was this statement under the Informational section:
    "The average disk queue length is 1. The disk may be at its maximum transfer capacity due to throughput and disk seeks"
    There was a link to do a Disk Diagnostic, which I went to. It led me to the Defragmenter, which is set to run automatically on a weekly basis. I ran the analysis anyway and it showed that 1% of the disk was fragmented. That doesn't seem like much to me.

    I have been monitoring, by opening the window every so often, the Task Manager and pretty much the levels for CPU, Memory and Disk remain high, with disk at 99 or 100 percent most of the time. It is constantly changing, of course, but here is a screen shot of kind of a "typical" reading.
    (Ooops, it wouldn't let me Insert an Image, so I have attached it.)

    I am using Internet Explorer 11, (I prefer Chrome but it got to where it would barely run, so I switched) and it is frequently at the top of the list of items using the resources. I usually listen to streaming radio but I am not doing that today, and it is still up there. I just looked and I am using 14% CPU 87% Memory and 1% disk. I just don't get what this is telling me. Thank you for your help.

    It's telling you that something is thrashing your disk. It looks like it may be the post update processing of Windows Updates. Can you right click on "Windows Modules Installer..." at the top and select Properties, then paste a screenshot of the properties?

    cheers, Paul

    Hi Paul,

    I guess the screenshot wasn't that typical. The Windows Module Installer doesn't even show up on the list anymore. I tried it on a couple of different days, trying to see if it would show up.

    I did try some things that I saw on some other posts, and maybe on this one too, I'm getting confused! :-) I turned off BITS, SuperFetch and WindowsSearch. These seemed to help with the disk usage but now Memory seems to always be running in the high 80%'s. CPU seems to be in the teens and 20's.

    Windows Module Installer does not run constantly.

    I would recommend running a System Health Report as mentioned in post #2

    Can you see a program that runs about the same time as the high disk activity?
    Is it an anti virus scan?
    I assume you are on a network, is something connecting to your computer at the time?

    cheers, Paul

    I did run the Performance Monitor the other day and it didn't really tell me much, as I referenced above.

    I ran it again just now and this time, there is more information, although I'm not sure what to do about it. An Error was reported, all it says is, "A service is reported as having an unexpected error code". That is a clickable link and that takes me to a section titled
    Abnormally Stopped System Service
    This tells me that Windows Media Player Network Sharing Service is the item that stopped. I don't know if that is significant or not.

    It also shows a Warning that "The system is experiencing excessive paging" when I click that link, it takes me to a list of "Files Causing Most Disk IOs" which tells me that:
    "The system is experiencing excessive paging

    Available memory on the system is low.

    The total physical memory on the system is not capable of handling the load.

    Upgrade the physical memory or reduce system load"

    I am all for the latter, if I could figure out how to do that. As I mentioned, there is a table showing the files causing the most disk IOs but nothing that tells me which ones are bad or how to fix it. I could post a picture of it, if it would be helpful.

    I know this is becoming Epic and I really appreciate you hanging in there with me. I'm sure this is fixable, just need to find that needle in the haystack. Thank you for your help.

    donebb,

    I am trying to run Performance Monitor in the way you are to get some sense of what you are seeing. Can you tell me how you are starting Performance Monitor and what you are clicking on to get those results?

    Thanks

    I suspected as much - post #4. You either need to run fewer programs or install more memory.

    Hi Paul,

    I don't think that's it. About 20 minutes after I started the computer this morning, the only thing I had running was IE11 with 2 tabs open, and the disk usage was pegged at 100%. I think it is trying to do something and is in some kind of loop or I don't know what. Thx.

    I would look at a couple of things...

    1. In Control Panel > Administrative Tools select Task Scheduler.

    See if there are any tasks that run around the time(s) you notice a CPU spike.

    2. Download Autoruns from Sysinternals.com

    https://technet.microsoft.com/en-us/...rnals/bb963902

    4. Unzip the file and double-click on Autoruns.exe. When you open it, Autoruns will begin to scan automatically. Press the ESC key to stop the first scan.

    5. In the Autoruns toolbar, select Options.

    6. Click on Scan Options and check the boxes Verify Code Signatures and Check Virustotal.com

    7. Click on the Rescan button in the dialog box.

    (Note: You will only need to do steps 5, 6, and 7 once).

    Each entry will be checked against the VirusTotal scanners and any suspicious entries will be flagged.

    If you are unsure about the Autoruns results, after running a scan, click on File and select Save. A file called <Your Computer Name> with an extension of .arn will be saved to your Documents folder.

    You can post that file in the thread, and anyone with Autoruns will be able to open and read it as if it were a scan of their computer.
