How to fix Blue screen error in Windows
When you start Windows, your computer may briefly display the blue startup screen and then continuously restart.
This behavior can occur if the following conditions exist:
- A fatal system error (STOP error) causes the computer to stop.
- The automatically Reboot option is enabled under Recovery on the Startup/Shutdown tab in the System properties.
Note: In Windows Server 2000, the Automatically Reboot option is enabled in the Startup and Recovery dialog box. This dialog box appears after you click the Startup and Recovery button on the advanced tab in the System properties. - The Windows paging file is smaller than the amount of physical memory installed in the computer or there is insufficient free space on the system hard disk to write the error dump file (Memory.dmp).
This section, technique, or task contains steps that tell you how to amend the registry. However, serious problems might occur if you modify the registry imperfectly. Therefore, make sure that you follow these steps carefully. For extra protection, back up the registry before you modify it. Then, you can repair the registry if a problem occurs.
NOTE: To work around this issue, you require a parallel installation of Windows.
To make the necessary changes, follow these steps:
- Install Windows to a similar folder.
- Run Regedt32.exe from the new installation of Windows, and then go to theHKEY_LOCAL_MACHINE key.
- On the Registry menu, click Load Hive, and then open the System file in the original Windows installation place. By default, this installation is located at %SystemRoot%\System32\Config\System.
- Enter an arbitrary name when you get a prompt for a key name in the Load Hive window. This loads the original HKEY_LOCAL_MACHINE hive as a sub key of the current key.
- Change the value data in the Auto-Reboot value to 0 (zero), instead of 1, in the following key: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Crash Control
- Collapse the HKEY_LOCAL_MACHINE sub-key and unload the hive.
This disables the automatic Reboot option in the unique Windows installation. After you follow these steps, you may be able to gather information from the STOP error message and resolve the problem that prevents the PC from starting. Another work around may be necessary if the minimum size of the paging file is set to a value less than the sum of physical memory. Windows requires a paging file on the system drive large enough to hold all of physical memory, plus 1 megabyte (MB), to write debugging information. You can modify the Paging Files value of the original installation so that the dump file can be created by the STOP error message. Sufficient free disk space must be available on the system drive for the paging file.
Follow these steps to change the paging files value in the System file in the original Windows installation location:
- Follow steps 1-4 from the earlier workaround.
- Change the data value of the Paging Files value to allow a minimum value of the amount of physical memory plus 1 MB, but not greater than the amount of free space on the hard disk. The key name is: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Memory Management
For example :- “drive:\pagefile.sys nnnnnn” where drive is the letter of the system hard disk and nnn is a number for the minimum and maximum size of the paging file.
- Check the following key to verify that the Crash Dump Enabled value is set to a data value of 1:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Crash Control
- Subside the HKEY_LOCAL_MACHINE sub key and unload the hive.
- Attempt to start the original installation of Windows and the STOP error message should appear. The unload information is stored in the paging file.
- Restart the computer and select the equivalent installation of Windows. This allows the dump file to be turned and you may be able to use the information to resolve the problem that causes the STOP error message in the original installation.
Windows may come across a problem during startup that results in a STOP error message. Depending on the pc configuration, the blue screen may not be displayed long enough to record the error information. Using the work around listed above, you can change the startup procedure so that important information about the STOP error message can be collected.
