To resolve the stop C000021A Fatal System Error on your PC try the following solutions:
If the error occurred after you recently installed a new program, then it is advisable to remove that program. The error occurs due to the incompatibility of the program.

Once removed, not reboot your PC. Reinstall a compatible program and run it. It is most likely to resolve the issue. However, if the stop C000021A error still occurs, then it means the problem is critical. It is related to the registry.
This procedure is slightly long and tricky.
To try it, you need to be technically sound. Here’s what you have to do: first create a parallel installation of Windows NT.
Start your PC to the parallel installation and then open the Registry Editor. On the Registry Editor’s Windows menu click HKEY_LOCAL_MACHINE on Local Machine and then click Load Hive.
Now type the path %systemroot%system32configsystem into the System hive of the prior installation. Then click open. Here you will be prompted to enter the name of the key, type TEST.
Note the setting for the current DWord value in the preceding registry key. This is 0x1 and is denoted by CURRENT:Reg_Dword: 0x1.
This value indicated that the Current Control Set for your original Windows NT installation corresponds to ControlSet001 in this window. Now if the value is 2, it indicated that the Current Control Set corresponds to ControlSet002.
Now locate the following registry key:
HKEY_LOCAL_MACHINETESTControlSetXXXControlSession Manager. XXX is the Current Control Set Value. And delete any pending file rename operation entries. Then click TEST hive and then click Unload Hive. After that again repeat the process, open the registry menu and click load hive, here type the path %systemroot%system32configSoftware to the Software hive of the prior installation and then click open.
Now you type TEST 2 when you are prompted for the name of the key. Remove any pending file rename operations entries in the following registry keys:
HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnce
HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnceEx
Now click TEST2 hive and then click unload hive. Quit the Registry Editor and then restart your original installation.
This will resolve the stop C000021A error.
