A friend called me last night desperate. She is leaving town to go home in 2 days and her PC shut down last night. Every time she re-boots she receives a BSOD with the C0000021a error. I have tried SAFE mode to no avail, and also attempted to boot using last know good config. No good. I also tried the "Repair the Computer" option during boot. Nothing is working.
I have also attempted CHKSDK /f and even though it found and corrected errors, the same BSOD appears.
We do not have the original PC disks as they are at her home.
The PC is a Dell Laptop. I'm currently offloading her files to an external drive via KNOPPIX so that at least we save her documents, pictures and music. Please help me try to get the PC operational again.

As soon as I can. May be a few hours. Currently running chkdsk /f /r and it's very slow. This was started before I saw your post.

It does no harm to have tried it anyway.

It is too late here and I'm going to sleep now. Please don't change the state of the system until we have the log and see if we can spot something. There are of course more options to try but i would like to postpone that until we have the log.

I see the system restore is already tried. Also is tried to rebuild BCD. So there are not really much options here.

We can take a look at the logs created to see if we can spot anything. We are going to copy those logs from the computer to the flash drive.

  • Open notepad. Please copy the contents of the code box below. To do this highlight the contents of the box and right click on it. Paste this into the open notepad. Save it on the flashdrive as fixlist.txt

    cmd: copy /y C:\Windows\ntbtlog.txt f:\
    cmd: copy /y C:\Windows\*?????pctlsp.log f:\
    cmd: copy /y C:\Windows\PFRO.log f:\
    cmd: copy /y C:\Windows\WindowsUpdate.log f:\
    
    Now please enter System Recovery Options.
    Run FRST and press the Fix button just once and wait.
    The tool will make a log on the flashdrive (Fixlog.txt) please post it to your reply.
  • There will be 3 files with names: ntbtlog.txt, PFRO.log and WindowsUpdate.log.
    Also there will be one or more files with the name ending with pctlsp.log (there will be about 6 characters then pctlsp like xxxxxxpctlsp.log) we need the one that is created on 2010-12-29 22:23.
    Please upload those files one by one or zip them and upload the zipped file to:

    To submit the files:
  • Click on this link: http://www.bleepingcomputer.com/submit-malware.php?channel=66
  • Click Browse... and navigate to the file and highlight it to select.
  • Click Open.
  • Copy the link to this topic in the appropriate box.
  • Click Send File.

I uploaded the first 2 files, but I only put in the topic number (370576). I cannot find any references to the log files *pctlsp.log.
Do I need to re-upload the files with the entire topic link ?
UPDATE: Re-uploaded with full link.

Thanks for the files, I'll get them with or without a reference.

Let's see if this will do to get the other file.

In command window type: notepad
Under Files menu click Open > Computer > C:\Windows
In the box Files of types check All files to see all the files.
In the Windows folder look for the file *pctlsp.log, right- click it and check the date: 2010-12-29 22:23.
Then right-click >copy > paste it to the flash drive to upload it.
