How to repair BSOD STOP: c000021a logon terminated with a status of 0xc0000005 (0x00000000 0x00000000)

Answers :

That's a real pain, 0xc000021a indicates that the actual Windows logon procedure has failed/terminated/crashed because it can't run/start the needed code (= 0xc0000005).
\015\012In other words: some files needed by Windows to start the logon sequence are corrupt. This can be caused by a faulty Windows Update or (perhaps more likely) a virus or spyware.
\015\012The problem with this kind of BSOD is that you can't boot into safe mode and that choosing "Last known good configuration" in the Windows XP boot menu (accessed by pressing F8 directly after the BIOS startup screen) probably won't work either.
\015\012All this means that manually repairing it is very hard, unless you really know what you're doing. Your best chance is booting from the original Windows setup CD and choosing the "Repair an existing Windows installation". You can find a detailed guide here: http://pcsupport.about.com/od/operatingsystems/ss/instxprepair1.htm
\015\012When the repair succeeds and you're able to logon to Windows again, it's best to just save all your personal documents, e-mail, etc. on an external HDD or burn them on a CD/DVD and do a full clean reinstall of Windows afterwards.
\015\012Please note that after "repairing" some installed programs may not work anymore and need reinstalling. And a repaired Windows (especially when it might have been infected with malware before) is like a car which is 'fixed' after a heavy crash, you'd better stay away from it ...
See this link and scroll down to the 0xc000021a section for a description of this error. Also see this MS article. and this article. This error could be an indication of malware installed on your system.
\015\012Try F8 at boot and choose last known good configuration...
\015\012If you get windows to load, follow the first four steps of this malware removal guide before rebooting your system..
\015\012If that doesn't work, you will need to use the recovery console, by booting from a recovery or installation disk. See here. You can receive help with this here or here.
