<windows root>\system32\hal.dll file is


Resolution

1. Restart the PC. The hal.dll error could be a fluke.

2. Check for proper boot order in BIOS. You might see the hal.dll error if the boot order in BIOS is first looking at a hard drive other than your main hard drive.

Note: If you've recently changed your boot order or recently flashed your BIOS, this may be what's causing your problem.

3. Run Windows XP System Restore from a command prompt. If this doesn't work or you're receiving the hal.dll error message before you're able to complete this process, move on to the next step.

4. Repair or replace the boot.ini file. This will work if the cause of the problem is actually Windows XP's boot.ini file and not the hal.dll file, which is often times the case.

Note: If repairing the boot.ini does correct the hal.dll issue but the problem reappears after a reboot and you've recently installed Internet Explorer 8 in Windows XP, uninstall IE8. In this specific situation, IE8 could be the root cause of your hal.dll problem.

5. Write a new partition boot sector to the Windows XP system partition. If the partition boot sector has become corrupt or isn't properly configured, you may receive the hal.dll error.

6. Recover data from any bad sectors on your hard drive. If the physical part of your hard drive that stores any part of the hal.dll file has been damaged, you're likely to see errors like this.

7. Restore the hal.dll file from the Windows XP CD. If the hal.dll file is truly the cause of the problem, restoring it from the original Windows XP CD may do the trick.

8. Perform a repair installation of Windows XP. This type of installation should replace any missing or corrupt files. Continue troubleshooting if this does not resolve the issue.

9. Perform a clean installation of Windows XP. This type of installation will completely remove Windows XP from your PC and install it again from scratch.

Note: While this will almost certainly resolve any hal.dll errors, it is a time consuming process due to the fact that all of your data must be backed up and then later restored.

Important: If you can't gain access to your files to back them up, you should understand that you will lose them all if you continue with a clean installation of Windows XP.

10. Test the hard drive. If all else has failed, including the clean installation from the last step, you're most likely facing a hardware issue with your hard drive but you'll want to test it to be sure.

If the drive fails any of your tests, replace the hard drive and then complete a "new" installation of Windows XP.

When i try to shut down my computer a blue screen appears with an error report : stop:c000021a {fatal system error}


Hi there,

This is the cause:
The STOP 0xC000021A error occurs when either Winlogon.exe or Csrss.exe fails. When the Windows NT kernel detects that either of these processes has stopped, it stops the system and raises the STOP 0xC000021A error. This error may have several causes. Among them are the following:
  • Mismatched system files have been installed.
  • A Service Pack installation has failed.
  • A backup program that is used to restore a hard disk did not correctly restore files that may have been in use.
  • An incompatible third-party program has been installed.
If possible contact a local technician to the do the below,if you are not sure of this process.
and also ask him to take a backup of your registry keys and create a system restore point without fail.

To troubleshoot this problem, you must determine which of these processes failed and why.


To determine which process failed, register Dr. Watson as the default system debugger (if it is not already the default debugger). Dr. Watson for Windows NT logs diagnostic information about process failures to a log file (Drwtsn32.log). Also, you can configure this program to produce memory dump files of failed processes that you can analyze in a debugger to determine why a process fails.

To set up Dr. Watson to trap user-mode program errors, follow these steps:
  1. At a command prompt, type System Root\System32\Drwtsn32.exe -I, and then press ENTER.

    This command configures Dr. Watson as the default system debugger.
  2. At a command prompt, type System Root\System32\Drwtsn32.exe, and then select the following options: Append to existing log file
    Create crash dump
    Visual Notification
  3. After the computer restarts from the STOP 0xC000021A error, run Dr. Watson (Drwtsn32.exe).
  4. View the Dr. Watson log to determine what user mode process may be causing the problem.
  5. If the Dr. Watson log does not contain sufficient information to determine the cause of the problem, analyze the User.dmp file to determine the cause of the STOP 0xC000021A error.

    If Dr. Watson did not create a User.dmp file for either Winlogon.exe or Csrss.exe, you may have to use a different tool to generate a memory dump file of the process that fails. For more information, click the following article number to view the article in the Microsoft Knowledge Base: 241215 (http://support.microsoft.com/kb/241215/ ) How to use the Userdump.exe tool to create a dump file Note Follow the instructions in the Knowledge Base article to troubleshoot a process that shuts down with an exception. While you follow these instructions, monitor the following processes to troubleshoot the STOP 0xC000021A error:
    • Winlogon.exe
    • Csrss.exe
    Note Most STOP 0xC000021A errors occur because Winlogon.exe fails. This typically occurs because of a faulty third-party Graphical Identification and Authentication (GINA) DLL. The GINA is a replaceable DLL component that Winlogon.exe loads. The GINA implements the authentication policy of the interactive logon model. The GINA performs all identification and authentication user interactions.
It is very common for certain types of remote control software to replace the default Windows GINA DLL (Msgina.dll). Therefore, a good first step is to examine the system to see if it has a third-party GINA DLL. To do this, locate the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Value = GinaDLL REG_SZ
  • If the Gina DLL value is present and if it is anything other than Msgina.dll, it probably means that a third-party product has changed this value.
  • If this value is not present, the system uses Msgina.dll as the default GINA DLL.
If this error first occurred after the installation of a new or updated device driver, system service, or third-party program, the new software should be removed or disabled. Contact the manufacturer of the software to see if an update is available. For more information about hardware and software vendor contact information, visit the following Microsoft Web site: - http://support.microsoft.com/gp/vendors (http://support.microsoft.com/gp/vendors) Last known good configuration If the previous steps in this article do not resolve the problem, start the computer by using the last known good configuration. To start the computer by using the last known good configuration, follow these steps:Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.
  1. Click Start, and then click Shut Down.
  2. Click Restart, and then click OK.
  3. Press F8 at the indicated time:
    • For an x86-based computer: When a screen of text appears and then disappears , press F8. (The screen of text may include a memory test, lines about the BIOS, and other lines.) There may also be a prompt that tells you when to press F8.
    • For an Itanium architecture-based computer: After you make your selection from the boot menu, press F8. There may be a prompt that tells you when to press F8.
  4. Use the arrow keys to select Last Known Good Configuration, and then press ENTER.

    NUM LOCK must be off before the arrow keys on the numeric keypad will function.
  5. Use the arrow keys to highlight an operating system, and then press ENTER.

I make window on my pc but it take me a error stop:c0000221unknown hard errorsystemrootsystem32 tdll . dll


This problem may occur if the file that is described in the error message is corrupted. The following files are checked for integrity when Microsoft Windows XP starts:
  • All driver files (except those that are loaded by the system loader to start. the computer)
  • All dynamic-link libraries (DLLs), including User, Graphics Device Interface (GDI), Shell, Kernel, Ntdll, Crtdll, and others.
This problem may occur if you install an inappropriate driver for your hardware. For example, you receive one of the error messages that are described in the "Summary" section if you install a MIPS driver on an X86-based computer.

This problem may occur if an Iomega Zip drive is on the same integrated device electronics (IDE) cable as the hard disk drive.

The third-party products that this article discusses are manufactured by companies that are independent of Microsoft. Microsoft makes no warranty, implied or otherwise, regarding the performance or reliability of these products.

3. Start > Right-click “My Computer” > “Properties” > “System Restore” > Check box “Turn off restore on Hard disks”
4. Start > Run > type %temp% > Edit Select All > Shift-Delete
Reboot machine
1. Combofix.exe. This program will run on its own. Also, it will likely wish to reboot the machine. Let it complete.
