    Does it give any other information, such as a file being corrupt or not readable? Generally this error is due to a corrupt registry or failing hard drive.

    Have you tried booting in safe mode? If you can boot into safe mode, could be a driver issue.

    Hit F8 during boot (after manufacturers logo) and select safe mode.

    The blue screen appears during boot so this is not an option

    Not sure what to do, bar reinstall Windows. Any computer I've fixed could always get into safe mode. F8 always worked for me.

    What's the make and model of computer ? What OS ? Had you installed any hardware/software recently ? Do you have recovery disc if needed (I wouldn't go reinstalling Windows just yet as you'll lose all your data but Repair may be an option) ?

    Sounds like either a corrupted file system or registry if it's happening that quickly. You'll need a way to get in to repair it (like some sort of system repair disc or connect hard drive as a second drive to another computer with same OS).

    My experience with this type of problem has ranged from relatively quick fix to trying all sorts of workarounds (not a repair for the average user, imo). A reinstall as the first thing to try is not the best advice.

    What I would advise is to try and get your critical documents backed up first before delving too deep into fixing issue.

    STOP: 0xC000021A

    Cause

    This error occurs when a user-mode subsystem, such as WinLogon or the Client Server Run-Time Subsystem (CSRSS), has been fatally compromised and security can no longer be guaranteed. In response, the operating system switches to kernel mode. Microsoft Windows cannot run without WinLogon or CSRSS. Therefore, this is one of the few cases where the failure of a user-mode service can shut down the system.

    Mismatched system files can also cause this error. This can occur if you have restored your hard disk from a backup. Some backup programs might skip restoring system files that they determine are in use.
    Resolving the Problem

    Running the kernel debugger is not useful in this situation because the actual error occurred in a user-mode process.

    Resolving an error in a user-mode device driver, system service, or third-party application:Because bug check 0xC000021A occurs in a user-mode process, the most common culprits are third-party applications. If the error occurred after the installation of a new or updated device driver, system service, or third-party application, the new software should be removed or disabled. Contact the manufacturer of the software about a possible update.

    If the error occurs during system startup, restart your computer, and press F8 at the character-based menu that displays the operating system choices. At the resulting WindowsAdvanced Options menu, choose the Last Known Good Configuration option. This option is most effective when only one driver or service is added at a time. If this does not resolve the error, try manually removing the offending software. If the system partition is formatted with file allocation table (FAT), use an MS-DOS startup disk to gain access to the computer's hard disk. If the system partition is formatted with NTFS file system, you might be able to use Safe Mode to rename or delete the faulty software. If the faulty software is used as part of the system startup process in Safe Mode, you need to start the computer using the Recovery Console in order to access the file. If a newly installed piece if hardware is suspected, remove it to see if this resolves the issue.

    Try running the Emergency Recovery Disk (ERD) and allow the system to repair any errors that it detects.

    Resolving a mismatched system file problem: If you have recently restored your hard disk from a backup, check if there is an updated version of the Backup/Restore program available from the manufacturer. Make sure the latest Windows Service Pack is installed.

    Look in the Event Viewer to see if anything is reported about those.

    TIP - Options - Advanced Filter allows you to see a time frame instead of the whole file.

    This is my generic bluescreen troubleshooter - you can try Safe Mode as suggested in the article
    above - repeatedly tap F8 as you boot. Vista disks are probably needed - if you do not have to try
    repair you can borrow a friends as they are not copy protected. Also you can buy the physical disks
    from the system maker cheap as you already own Windows (you will need these to reinstall if
    required). You can also make repair disks on another computer.

    Here are some methods to possibly fix the blue screen issue. If you could give the Blue Screen info
    that would help. Such as the BCC and the other 4 entries on the lower left. And any other error
    information such as STOP codes and info such as IRQL_NOT_LESS_OR_EQUAL or PAGE_FAULT_IN_NONPAGED_AREA and similar messages.

    As examples :

    BCCode: 116
    BCP1: 87BC9510
    BCP2: 8C013D80
    BCP3: 00000000
    BCP4: 00000002

    or in this format :

    Stop: 0x00000000 (oxoooooooo oxoooooooo oxooooooooo oxoooooooo)
    tcpip.sys - Address 0x00000000 base at 0x000000000 DateStamp 0x000000000

    Many BlueScreens are caused by old or corrupted drivers, especially video drivers however there
    are other causes.

    You can do these in Safe Mode if needed or from Command Prompt from Vista DVD or Recovery
    Options if your system has that installed by the maker.
