Window 7 freezes and windows lose focus RRS feed

  • Question

  • This problem is on a Dell desktop running 32-bit Windows 7.  All was well for a long while, then suddenly, the pc started losing focus for programs that were open.

    The programs can include both internet browser windows or local programs.  The problem is completely intermittent.

    When it happens,  the mouse still moves the pointer, but it won't actually do anything.  The window controls (close, maximize, minimize) are greyed out and there is no way to do anything in the running programs.  The only way to get control back is to start Task Manager.  By just opening Task Manager, the problem is temporarily cleared and everything is normal again for a while until the next occurrence.

    All updates have been done on the machine; all maintenance including defrag, error checking; Outlook data has been reindexed; Troubleshooting IE 8 yielded not beneficial results. Virus and malware checks came back clean.  Have looked in event logs for a clue, but could not find anything there.


    I really have no idea where to start to find anything that even might be a cause for this problem.

  • Hi,


    Thanks for the post!


    Does it happen in safe mode?

    When this freezing happened, were you running a lot of programs?

    Do you have a high CPU when this happened?


    For this freezing issue, we need to analyze the performance monitor logs and memory dump files to locate the root cause.

    You can refer to: Using Performance Monitor.


    For collecting the minidump files, follow these steps:


    1. Click "Start", input "SYSDM.CPL" (without quotation marks) in the “Search” bar and press “Enter”.

    2. Switch to the "Advanced" tab and click the "Settings" button under "Startup and Recovery".

    3. Under "Write debugging information" section, make sure the "Small memory dump (128KB)" option is selected.

    4. Make sure "%SystemRoot%\Minidump" is in the "Small dump directory" open box and click “OK”.


    If the freezing appears again, please refer to the following steps to collect memory dump files:


    1. Click “Start”, type “%SystemRoot%\Minidump" (without quotation marks) in “Search” bar and press “Enter”.

    2. Go to your Desktop, right-click on it and create a new folder named "Dump".

    3. Copy all the memory dump files (looks like [Mini092008-01.dmp]) in Minidump to this folder.

    4. Right-click on the Dump folder, click "Send To", and click "Compressed (zipped) Folder".

    5. Please send the ZIP file to us.


    You can refer to the following link to upload the information:




    You may also analyze them with Debugging Tools by yourself. You can install it and it’s Symbol Packages from the following link:




    WinDbg will tell you the possible cause. For more information, please read Microsoft KB Article: How to read the small memory dump files that Windows creates for debugging.


    If no clue can be found, you may contact Microsoft Customer Service and Support (CSS) via telephone so that a dedicated Support Professional can assist with your request. To troubleshoot this kind of kernel crash issue, we need to debug the crashed system dump. Unfortunately, debugging is beyond what we can do in the forum. Please be advised that contacting phone support will be a charged call.


    To obtain the phone numbers for specific technology request please take a look at the web site listed below:
