    fl0bot,
    The message you are getting means that there is some corrupt system files that could not be fixed.  If you look in the CBS.log file , it should tell you which files.  When you do that, you can try to replace the corrupt files.  However this seems to happen whenever you update it a game then you will need to contact their support for aid as this can be a problem for them.  Mike - Engineer Support Microsoft Answers

    My computer also usually during start-up will go to a disk check, it goes through the process and restarts, but I never noticed a difference in the performance of the computer. My computer crashes also up and I have to restart manually, sometimes several times.

    I ran malwarebytes and it is clean, MiniToolBox deleted three things, run ESET scan and it was clean.

    I get occasional blue screens, sometimes they say 'bad pool head' but I don't know what that means.

    I had blue screens and I worked with someone online ran many scans and could not find any problems and suspect it is the hard drive. I was under warranty and I replaced the hard drive, but I always get blue screens. My windows updates are underway, all my programs are up to date.

    I don't know what to do with this problem. I really need help.

    Any help to fix this would be greatly appreciated. Thank you!

    Hello

    ·         You get a code of error with blue screen "bad pool head '?

    Follow these methods and check if that helps.

    Method 1:

    Step 1:

    Check if you have the similar problem in safe mode, otherwise you can try to put your computer to a State of clean boot in normal mode and check if it works:

    Start your computer in safe mode

    http://Windows.Microsoft.com/en-us/Windows-Vista/start-your-computer-in-safe-mode

     

    Step 2:

    Follow the article to perform the clean boot on the computer:

    How to troubleshoot a problem by performing a clean boot in Windows Vista and Windows 7

    http://support.Microsoft.com/kb/929135

    Warning: After using the boot is a way to solve your problem step 7 follow-up to reset the computer to start as usual.

     

    Method 2:

    I suggest that you try to perform the SFC (System File Checker) scan on your computer and check if the problem still persists. To see how to the SFC Scan click on the link below and follow the steps in the Kb article.

    How to use the System File Checker tool to fix the system files missing or corrupted on Windows Vista or Windows 7

    http://support.Microsoft.com/kb/929833

    Method 3:

    Follow the steps in the article, and check if that helps.

    How to fix BlueScreen (STOP) errors that cause Windows Vista to shut down or restart unexpectedly

    http://support.Microsoft.com/kb/958233

     

     

    Method 4:

    A pool header problem is a problem with the allocation of memory for Windows. Device driver problems are probably the most common, but it can have various causes, including defective or other writing problems disc and problems with some routers. (In theory, RAM problems would be suspect for pool memory problems).

    If you have Windows Vista DVD you can try to run the Startup Repair and The Windows Memory Diagnostic tool to check and Windows Recovery mode if it helps.

    What are the system recovery options in Windows Vista?

    http://Windows.Microsoft.com/en-us/Windows-Vista/what-are-the-system-recovery-options-in-Windows-Vista

    Alternatively, you can use the command prompt on the recovery mode windows to perform analysis and error correction on a drive letter of your choice by running "chkdsk x:" where x is the letter of your drive. Type the below command on command prompt, and then press ENTER:

     

    X:\>chkdsk/f

    /F Corrects errors on the disk

     

    Important: Running chkdsk on the drive if bad sectors are found on the disk hard when chkdsk attempts to repair this area if all available on which data may be lost

  • How to get the State of the MAF springboard?

    Hi Experts,

    Currently, I have created with toggle button and drag right springboard. Each tap/hit will set a Boolean attribute within the bean. This property is set to true if the platform is open and False if the springboard is closed.

    However, this method does not smooth, if user press android back button or navigate to the other feature (this can be managed). They need to tap/double (x 2) to open the springboard

    I wonder if there is a (standard) way to get the State of springboard so that I didn't need to create a Boolean variable and set manually.



    Best regards

    Hendry

    If you have a custom springboard so you can get the id of the function and compare:

    AdfmfJavaUtilities.getFeatureId () or AdfmfJavaUtilities.getFeatureName)

    I don't know what the next method returns but can be useful:

    AdfmfJavaUtilities.getFeatureContext () .getCurrentState)

  • Package in an invalid state - compiles ok

    If I try to call a procedure in the package says "ORA-06575 package or the function is in an invalid state.»

  • Question of recursive function

    I used the recursive functions with other programming languages, but I seem to have a problem using a UDF in a SWC file. I am reading a file XSD, by analyzing the XSD and filling a table with details of any import using XMLSearch tag, passing by the table and calling the UDF even to treat the file XSD child, so on a recursively etc. My problem occurs when the UDF gets to the bottom of the recursive call is going up a level from one loop to the next item in the table of the parent UDF call. When the code back, it gives me an error saying that "the item at position 2 is not found." After some difficulty in finding what's going on, it seems that the values in the table have been purged. From my experience with the recursive functions, the values of all the calls will remain available in memory after returns to him. I'm a litte green using UDFs, but I think it should work the same way. Is there a problem with the scope of the array variable that I use? I have attached my code. Any help is appreciated. Thank you!

    Is there a problem with the scope of the array variable that I use? I have
    attached is my code. Any help is appreciated. Thank you!

    Yes, in the CF variables that are not limited in a CFC function (NOT a UDF
    by the way) are placed in the PRESENT field of application, which is accessible to all
    functions in all iterations and users outside of the CFC as well.

    To declare local variables to the function at the current
    iteration, you must use the var scope

    for example.

    You can also watch some of you other sets of variables. Don't you
    you want to set this value EACH iteration?

  • dependencies on view (how to get invalid)

    Hi guys,.

    has been read the guide of the notion and came across this

    his chapter on pages 157 6-5
    under

    < data storage considerations >

    < i >
    Remove indexes on the tables at night to facilitate faster loading data warehouses.
    However, all dependent views on the table on which the index is moved becomes invalid.
    This means that eventually run no matter what package that reference these abandoned
    views will invalidate the package.
    Remember that whenever you create a table, index, and display and then delete the index,
    all dependent objects on the table are invalidated, including views, packages, package
    organs, functions and procedures. This protects the editable join views. < /i >

    did a test but does not seem to be what is described above.

    Scott@ORCL > create index testidx on dept (dname);
    The index is created.

    Scott@ORCL > create the display of the view in SELECT * FROM DEPT;

    Have two old CD/DVD with the old movies of family 8mm on them.  When I try toopen them I get a statement that ' cannot they in format Samsung "suggestions?

    that is a difficult question. Try VLC to see if it will open to them. Usually when the disc appears on the desktop, if you click on it and let go, then press the clover sheet and I (get info command), you should be able to choose which application/program can open them. I have not already heard talk of the "samsung" format, I know there is a stranger there (lie format MTS from Sony). Regarding the conversion of them, maybe MPEG streamclip or hand brake? worst case scenario, you may need to spend some money to buy a video conversion app/program

    Hi obyry,

    1. did you of recent changes on the computer?

    2. do you have security software installed on the computer?

    It is possible that some third-party programs installed on the computer is causing the problem.

    I suggest that you put the computer in a clean boot state and check if it helps.

    To help resolve the error and other messages, you can start Windows XP by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    See the link below to learn more about how to clean boot.

    How to configure Windows XP to start in a "clean boot" State

    Reset the computer to start as usual

    When you are finished troubleshooting, follow these steps to reset the computer to start as usual:

    (a) click Start, type msconfig in the search box and press ENTER.

    (b) If you are prompted for an administrator password or for confirmation, type your password or click on continue.

    (c) under the general tab, click the Normal startup option, and then click OK.

    (d) when you are prompted to restart the computer, click on restart.

    Hello retabox, welcome.

    It would seem that the installer is corrupted. I recommend trying to use the Windows Installer Cleanup utility to force - to remove the application. Try this:
    2. click on the download link in the middle of the page
    3. save the file to your desktop or just click Run the installation of the application
    4. once the application is installed, open the utility. The utility must be located in the menu START under (START > programs > Windows Installer...)
    5. in the utility, find the application you want to uninstall, and then click the button 'delete' below
    6. once removed, restart the computer and see if you can reinstall the application
