Windows 7 32 bit lockup - Hard reset needed RRS feed

  • Question

  • Hi,

    I'm using Windows 7 Professional 32 bit and I keep having issues with lockups. The screen freezes and I'm unable to use the mouse, the only thing I can do is a hard reset. What I have done so far is: -

    - Memory test - All seems fine
    - Hard drive has been replaced recently and error checked and all ok
    - Installed latest video drivers but did the same with the Microsoft drivers
    - Cleaned all the dust of internal components and replaced the thermal paste
    - Checked for errors in the event log but nothing appears other than the message saying the restart was unexpected
    - Disabled Hibernation in case it wasn't helping

    I thought I'd cracked it with the clean out but yesterday it locked up again after 6 days being ok. I can't see any pattern as to software running which could cause this but also can't see any indications in the event log that something's wrong. I was connected to it via Remote Desktop when it locked up so it shouldn't have gone to sleep anyway

    Anyone got any ideas what else I can try?

    Thanks in advance

    Chris

  • Drivers, because they run at a low level, can cause lockups.

    Have you checked, for example, to see if your display driver is up to date?  Visit the web site of the maker of you video card (e.g., nVidia.com or ATI.com) and see what they offer for your hardware and OS.  Usually it's better to get drivers directly from the manufacturer than through Microsoft's WHQL.  You wouldn't think so, but quite often newer is better, and the Microsoft-served versions are usually older.

    And your instinct that it could be hardware failure isn't necessarily wrong...  Memory, for example, can fail to read back what was written in.  Do you have ECC memory?

    Do you have any diagnostics specific to your system that you can run?

  • check to make sure the memory is seated correctly, sometimes a loose DIMM can be problematic

    goto memtest.org and download the cd/usb version and check the memory for problems

  • Hi Chris,

    Usually, a server can appear to hang (stop responding) in the situations of insufficient system resources, high CPU usage, high disk usage, deadlock in kernel mode or key system processes, or hardware problem. To troubleshooting the issue efficiently, it is important to understand the exact symptom.

    I guess you must alread checked the event log, and there is no event related the insufficient of resources. So, maybe there is a deadlock in kernel mode, and caused the hang issue.

    In most of the hang cases, the hardware drivers and the antivirus dirvers are first suspected.

    So, it is still recommended to apply all the updates for all the hardware drivers and firmware, and BIOS. Then stop the anti-virus software if you installed.

    After that, if the Hang issue still occurs, maybe you can capture a Dump file manually, but we need to enable this feature:

    We can configure the Ctrl+Scroll+Scroll feature to enable manually creating memory dump when the PC becomes unresponsive. To enable this feature, please do the following steps:
    ====================
    a. It will be better if you can plug a PS/2 keyboard directly to the computer. If you don't have a PS/2 keyboard or PS/2 port, you can still try USB keyboard.
    b. Run regedit to open Registry Editor.
    c. If you are using a PS/2 keyboard, locate the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters 
    d. On the Edit menu, click Add Value, and then add the following registry entry:
    Name : CrashOnCtrlScroll
    Data Type : REG_DWORD
    Value : 1 
    e. If you are using a USB keyboard, please add CrashOnCtrlScroll under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\kbdhid\Parameters.
    f. Exit Registry Editor, and then restart the computer. 
     
    For more information, please refer to the following KB articles:

    http://support.microsoft.com/default.aspx?scid=kb;EN-US;969028
     
    To ensure that a memory dump could be created successfully, please configure memory dump settings per the steps below:
    =====================
    a. Click Start -> Control Panel -> System, and go to advanced tab.
    b. Click "Settings" in "Startup and Recovery" section.
    c. In "System failure" section, uncheck "Automatically restart", choose "Complete memory dump", and click OK.
    d. Click "Settings" in "Performance" section, and set page file on C: to be larger than your physical memory size.
    e. Click OK to save the settings, and restart the server.
     
    Next time when the issue occurs, please press Right Ctrl+Scroll+Scroll (hold down Right Ctrl, and press Scroll Lock twice) to manually create a blue screen, and wait until it finishes saving the memory dump. After rebooting, Please let me know, i would like to provide a FTP space for you to upload it.

    Thanks.

  • Hi Vegan/Noel,

    Thanks for your replies. To answer both questions in one, here's the specs

     

    Advent T9208 (with modifications)

    Processor - Intel Pentium D 945 processor (3.4 GHz)

    Memory (4x 512MB DDR PC2-6400) - Non ECC

    Motherboard MSI (Micro Star) MS-7187

    2TB Western Digital Drive

    Graphics - ATI Radeon HD 4600 Series

     

    To answer the other questions, yes, I have installed the latest ATI drivers previously and it made no difference. I also don't have any diagnotics tools but did run the MS Memory test

    Regards

  • Hi,

     

    Thanks for posting in Microsoft TechNet forums.

     

    From the description, it seems suffer from random lockup, no matter which application is running. If I misunderstood, please correct.

     

    Given this situation, I would like to confirm if you have Windows 7 SP1 installed. If not, download Windows Vista SP1 from the link below according to the System Type:

     

    Windows Vista Service Pack 1 for Windows Vista 32-bit (Size: 544.3MB)

    http://www.microsoft.com/downloads/details.aspx?FamilyID=f559842a-9c9b-4579-b64a-09146a0ba746&DisplayLang=en

     

    If yes, let us boot into Safe Mode to check if the issue persists.

     

    Best Regards

  • Hi,

    Yes, I already have SP1 installed. Running in safe mode isn't really going to help much as the problem is so intermittant. As mentioned, it ran for 6 days and it was fine but then locked up. I don't think working on it in safe mode is going to help much as I won't be able to do much on the machine anyway.

    Is there any way of getting more information into the event log?

    I'm going to try Vegan's suggestion later to check the memory using a different tool and see what happens, I'll also reseat the memory just in case.

    Regards

    Chris 

    Monday, September 5, 2011 7:45 AM
  • Hi Vegan,

    Thanks for the suggestion. Checked the memory seating and all ok. Ran the memory test as you advised and it passed ok without any errors

    Any other ideas?

    Regards

    Chris

    Monday, September 5, 2011 7:22 PM
  • No, there's no BIOS updates available for the board

    I can understand the reason for running in safe mode but it's going to be too limited to use and not really going to help much other than tell me it's drivers which seems the logical option already. I'll try the suggestion with the USB devices and see what happens

    Regards

  • Yes, looking at what your report has shown up, it does look like a mess. Where does your tool read the information from though as I can't see any duplicates in program files or HKLM\Software although it's probably reading from somewhere else?

    Yes, we do use the cannon software as it's got some useful photo maniplulation utilites that come with it. I'm not so keen on installing Microsoft Security Essentials as independant software review companies have said it's performance for proactive defence isn't up to the same standard as it's competitors

    SwishMax is used to create flash files. It was installed after the last lock up so I know it's not related. Removed ImgBurn so I'll see how I get on with the native solution

  • Hi,

    To validate or determine which service/startup item could be causing this, restart the computer and boot to desktop normally. Once done, perform clean boot.
     
    Clean Boot prevents software conflicts by preventing the startup items and non Microsoft services from loading. This way you can safely follow the process of elimination to check which application is causing this behavior.

    How about the result from clean boot?

    I have seen you have tried all kinds of troubleshooting steps on hardware side, what if the issue is due to conflict with third party software?

    I suggest try clean boot before formatting and reinstalling everything.

  • I've checked for duplciate GUID's for the following and they do exist although I have no idea how this happened

    4E52E5C90CE2F864E93FB30466D02909 - Windows Live Mail
    3CF865A380B0BC648AAB7BD2E0D0D78C - Windows Live Mail

    1F0F10557B51C764FBD31C2DE616AC13 - Windows Live Photo Common

    Won't this be down to the application vendor to decide whether to use the same GUID? Is this even likely to be the issue?

    From the posts so far it looks like it may be a third party app conflict so I'm going to remove items that I feel I could do without and see how I get on. I do have a system image creating in Windows 7 should I want to use it but I would like to resolve without using it

    It's still work in progress unfortunately. I thought I'd cracked it as it locked up last Friday when using TrueCrypt which I use to mount some encrypted files I use at work but then yesterday, when it wasn't in use it locked up again. I'll reply once I've figured out the root cause

  • Hey, I have been having the same lock ups. Updated everything possible and still happens.
    Have used some google powers to after finding a similarity in my event viewer with another sufferer.


    Event 10016: The application-specific permission settings do not grant Local Launch permission for the COM Server application with CLSID {C97FCC79-E628-407D-AE68-A06AD6D8B4D1}"

     

    check event viewer after one of the periods of freeze/lock up. If you find the above error (10016) it follow this link!
    http://social.technet.microsoft.com/Forums/en/w7itproperf/thread/77e2e957-53a7-4381-bf84-5905a583a1fc

    Some clever chap has posted a solution. I have followed the steps and have been running fine for a few hours now.  

    One more question, do you have an SSD installed? Google, SSD and turning superfetch off. In my event log i found superfetch errors, which have now gone due to superfetch being disabled.

    Ill recheck this for any updates you post and if my problem returns.
    Good luck to both of us! 

     
    Thursday, September 15, 2011 12:58 PM
  • Hi,

    Thanks for the reply. I've checked my logs and don't have the same errors as you so I'm guessing our problems are slightly different

    I have had 2 more lockups since so they are becoming more frequent. I did install the latest ATI driver with Catalyst Control Center yesterday to see if it made any difference but it didn't.

    I've now done a selective startup in msconfig with just limited programs turned on  (i.e. Antivirus only) so I'll see what happens now and report back

    Regards

After rebooting, Please let me know, i would like to provide a FTP space for you to upload it.

  • Hi,

    I gave up in the end and did a re-install of Windows 7. It did lockup but I couldn't force the memory dump after it had crashed, tested it before and the force dump worked ok but the lockup must have prevented it from working

    Anyway, I installed Windows as was half way through SP1 and it locked up again so I guess that rules out software conflicts. I've put in a spare graphics card and am seeing how I get on now. I'll let you know what happens but so far it seems ok

    Regards

    Chris
