IT Queries: Computer problems answered

I have a lenovo laptop running Windows XP that shows a blue screen when it is turned on. The message reads “STOP: c000021a {Fatal System Error} The windows Logon process system process terminated unexpectedly with a status of 0×00000000 (0×00000000 0×00000000). The system has been shut down.”

many thanks for your help.

Windows is trying to do something like rename or update a file on starting and failing. Microsoft explain the process here. As result the computer won’t start.

This isn’t simple to fix and we wouldn’t recommend Microsoft’s solution. Instead we would use a Knoppix or BartPE disk to repair the problem which may involve moving system files from a repair directory back to their correct location.

Using recovery disks such as Bart or Knoppix is not something we would recommend to inexperienced users. If you aren’t sure about any of this you should call a computer tech to do this for you.

It’s also possible your hard drive is damaged and you should get your computer tech to check this and make sure your important data is backed up.
