    W10 getting slower/lagging more (wondering if its somthing I've done)

    OK, so here is my setup

    Intel Celeron 3.06 GHZ with 2.5GB RAM

    Windows 10 Home
    Version 1511
    Build 10586.318
    32bit os, x64 based processor

    C: = 128GB ADATA SSD (System drive obviously)
    D: = 250GB Seagate Barracuda SATA HDD - Network shared (Data drive)
    E: = Writemaster Speedplus SATA CD/DVD read/writer
    T: = 80GB Seagate Barracuda SATA HDD - Network shared (Dropbox drive)
    B = 1.5TB Seagate USB HDD (Network Shared, used for backing up all the drives on my network using Seagate Diskwizard)

    When I first installed WIn 10 and installed all the regular sofware I use (Photoshop, ACDsee, Firefox, Nero and AVG), it was fast. But it has gotten slower and slower, and many operations have start to lag severely, for example

    - a warning dialog will appear, or a notification tab will appear in the bottom right corner of the screen, but the notification sound associated with that dialog/tab can be delayed by anything from 30 seconds to three minutes.

    - opening Photoshop or ACDsee or any program for that matter can take two minutes or more

    - even opening an already running pogram by clicking on its icon in the taskbar can often take 30 seconds

    - When opening "This PC" it can take 15 to 30 seconds "working on it" before the drives appear.

    - If I right-click on any those drives, the "blue circle of impatience" can spin for 30 seconds to a minute before the context menu appears.

    I am posting this on an XP computer attached to the same network as the Win 10 computer and accessing the Internet through the same access point (hardwired through a Linksys X3500 router). I am doing so because surfing the web on the Win 10 computer is near impossible. If it doesn't time out on any given website, I get a stream of "a script on this page has stopped responding" errors.

    One thing I have noticed is that in the Task Manager, an entry called "System Interrupts" is using between 30% and 60% of the CPU and regularly tops out at 99%, remaining there for long periods of time, 15 seconds to 30 seconds

    Here is what I have tried so far

    1. Pause syncing on Dropbox (in case its a nework issue)

    2. Disconnecting the network shares

    3. Disconnecting the USB Drive

    Could it be that having three phyical drives is impacting severerly on the system?

    ETA: Another thing that happens is when I open a folder with , say, 100 photos in it, no matter how O have the folder setup, i.e. thumbnails, details or whatever, any attempt to scroll down is met with the "blue circle". It takes at least a minute before I can use the folder functions, scrolling, clicking on an item, selecting using ctrl click, shift click etc.

    ETA2: And another thing I notice. When a window is open, there often appears a green progress bar running from left to right "behind" the address path of the folder. This progress bar runs continually about twice each minute. While the programme bar is moving, the blue circle is spinning, and I cannot do anything.

    1. Is all well in Safe Mode? Do you see any change in performance?
    If this is a driver problem - which given your comment on System Interrupts it probably is, then Safe Mode may be fine.

    Solved Help ! System Interrupts are running are crippling CPU - Windows 10 Forums

    & this old thread How to get the cause of high CPU usage by DPC / Interrupt - Windows Tips Tweaks - MSFN
    indicates how to diagnose it.

    Bearing in mind your note on system interrupts, download and run LatencyMon by Resplendence, and post screenshots of what it finds.

    If not a driver, some ideas:

    2. Drives.
    By all means try disconnecting drives you don't need and see what happens. Simplification is always best.
    But first check the SMART params of all your HDDs. (E.g. Crystaldiskinfo -freeware).

    3. Then do a basic check to see if anything you've installed is causing this.

    You may like to set a restore point before proceeding to easily get back to your current state.

    Clean Boot - Perform in Windows 10 to Troubleshoot Software Conflicts - Windows 10 Forums

    If the problem is still present after a clean boot, then download and run (or install and run) shellexview (free).
    Hide all MS extensions, disable the rest. (No need to log off etc).
    Note under options there's a 32 bit option which reveals more if running x64 '10.

    Thank you for the reply. You have given me a lot to think about.

    This is a work computer, and before I left work today, I did some of what was suggested in the clean boot tutorial; turned off everything that I installed. I found that, in the StartUp list., there were two instances of "The Folder Spy" (a program we use for giving an audible warning when files have arrived in certain folders from another computer on the network) I only reinstated one of them, and the problem seems to have disappeared, for now.

    I will check again on Monday. Thanks again!

    PS: Another question while I think about it. You say that the issue with high CPU use of "System Interrupts" could be a driver issue. I am assuming you mean hardware drivers (is there any other kind?) Do you mean hardware drivers as in peripheral hardware attached to the system? The only attached hardware I have is...

    1. Logitech Couch Mouse

    2. PS2 Keyboard (no rear ports left for a USB keyboard)

    3. Philips 190s monitor

    4. Epson R1900 printer (via network)

    5. Copal DPB1500 Dye Sublimation printer

    6. ATech Pro37U card reader

    The Copal printer driver was the one I had most difficulty finding as there is no actual certified Win10 driver for it. The nearest I could find was a WIn 7/8 driver which others in the industry have reported work just fine in WIn 10.

    "But first check the SMART params of all your HDDs."
    What should I be looking for?

    Hello, drivers include all the drivers associated with the hardware inside your PC, not just peripherals. (There are software only drivers too just to confuse things).

    A search about SMART parameters offers:
    SMART Parameters and Early Signs of a Failing Hard Disk | Hetman Software
    Download CrystalDiskInfo - MajorGeeks
    You are looking for no signs of failure. Hopefully.

    Please work thru what I suggested in #2 for starters.

    OK, so I am a little confused by the results. Here are some screenshots from you first suggestion, run LatencyMonClick image for larger version.

    I should say that during the time this was running, I did not have any issues, but the first time I ran it I was having the usual problems with System Interrupts hogging th CPU, and the text in green at the top was black and said something to the effect that there were problems with the tcp/ip driver and it was causing problems. The computer locked up enitrely before I had a chance to take a screen shot, and I had to restart.

    Next I looked at the Drivers tab...

    What I find confusing here is that the figures for Reallocated Sectors Count on the the two "caution" drives, D: and T:, arent a lot differen from this on the B drive, whic is reapoted as healthy

    B: 100 : 100 ; 36
    D: 100 : 100 : 36
    T: 99 :99 : 36

    Does this mean I am running out of spare sectors?

    PS: I will try running LatencyMon if the issues start up again.

    ETA: Forgot to add the LatencyMon text report

    Hi, thanks.
    I don't think I see a comment about Safe Mode performance- can you check that? - Helps to give a view of what's happening without a lot of the drivers.

    Would suggest you try booting normally with any disk drives you don't need disconnected (process of elimination).

    Although there's no significant warning given by Crystaldiskinfo, as a matter of routine, you may as well run chkdsk on the drives flagged as caution.

    Sector reallocation is a poor indicator of drive health. Some large drives don't have enough data (user submitted records of "good" drive information), so they default to the danger readings of much smaller drives.

    In short, you should worry if reallocated sectors is increasing consistently. If the number is constant after several boots, then it isn't a problem. If it increases consistently then you should be worried.

    Attribute Name: Reallocated Sectors Count
    Attribute ID: 05
    Description: Count of reallocated sectors. When the hard drive finds a read/write/verification error, it marks this sector as "reallocated" and transfers data to a special reserved area (spare area).
    This process is also known as remapping and "reallocated" sectors are called remaps. This is why, on a modern hard disks, you can not see "bad blocks" while testing the surface - all bad blocks are hidden in reallocated sectors. However, the more sectors that are reallocated, the more a sudden decrease (up to 10% and more) can be noticed in the disk read/write speed.
    Critical: Yes
    Hard drives that support this attribute: Samsung, Seagate, IBM (Hitachi), Fujitsu, Maxtor, WD (Western Digital)

    LatencyMon doesn't seem to indicate anything to me.

    I would as a matter of routine run
    chkdsk C: /F
    sfc /scannow
    - both from an elevated command prompt.

    if ok, then move on (assuming all was ok in Safe Mode to the clean boot test (my first post).

    The system hasn't "faulted" since I rebooted after the first attempt to run LatencyMon froze the computer, so I don't know if there really is a driver issue.

    The "fault" seems to appear right when I am in the middle of working, so the problem with disconnecting the drives is that even if they are causing the issues there will be no way to know. I need them to do the work I use the computer for because that is where all the data is. If I can't use the computer for work, then the fault likely won't appear.

    What I am going to have to try to do is keep working until the fault appears, then run LatencyMon while "System Interrupts" is going nuts!

    Its a similar problem with using Safe Mode. It won't prove anything because neither Photoshop nor ACDsee will run in Safe Mode (and the printer wont print) so I will not be able to reproduce the fault.

    Regrading your comment (1st post) about explorer not responding quickly with a folder of photos, you can try Shellexview (freeware); run it, hide all MS extensions, disable all others, and see if there's any effect. If you're using 64 but Windows, explore the 32 bit option in Options which will reveal more extensions.

    No need to log off- if this has an effect, you can diagnose cause.

    OK, that is another thing to try

    PS: My WIn 10 is 32 bit.
