Cannot boot problem

[Michael]

Hello:
I am using Windows XP Home Edition Service Pak 2.
What I try to boot, the black screen with the Windows log appears then the
laptop keeps rebooting.
I have been able to boot in Safe Mode, but not in the Last Known Good Config.
When I selected Disable automatic restart on system failure, it gave an
error message of 00000
Yours in hope

Michael, if you are able to boot into Safe Mode then try a system
restore. Start>All Programs>Accessories>System Tools>System Restore

Hi Barry
Thank you for your advice, much appreciated.
What I did yesterday, after writing this message, is I opened windows in the
Directory Services Restore Mode and did a System Restore to 10/21 and it
worked fine.
I am not sure though what the problem was since I did not download or delete
any applications lately.
Yesterday when I tried to boot using Disable automatic restart on system
failure, I got the following message
STOP: C000021a (fatal system error) the window logon process system
terminated unexpectedly with a status of 0xc000005. The system has been shut
down.
I am wondering what that means and why I had this problem.?
I ran scan disk from the Command Prompt and via My computer, but no errors
came back.
Should I do anything else?
Thanks
