STOP c000021a Windows Logon Process 0xc0000005

Ok, im getting that error code at windows boot up. The box says windows starting up, then the computer restarts and goes through the same cycle. I have went to numerous microsoft support site with no avail. This occured directly after installing a SP2 for XP Pro. Do I need to format and re-install, or is there another workaround? The only thing running at startup is Yahoo Messenger and Panda antivirus 2006. Any help would be awesome. Thanks in advance.

 

Recommend that you check the event logs for further diagnostic information. To do so, please do the following:

1. Right-click 'My Computer'
2. Select 'Manage'
3. On the 'Computer Management' window, expand 'Event Viewer'

Check the 'Application' and 'System' logs for red x's and/or yellow exclamation marks that correspond to the error messages you receive. Post back with the event id number, the source, and the description text.

 

Nice! Try this instead of my suggestion!

 

I've tried all that, nothing works. And to Mada, the system will not boot at all therefore your suggestion will not work. It will not boot in Safe Mode, nor with any other configuration. I can get to the logon screen in safe mode but when i enter my password it fails to load windows. Also, I cannot use a bootable xp cd. Even though the cd/r is being detected in the bios. Very peculiar happening this time. It's growing into a severe headache since even reformatting seems to be impossible at this point. Keep them suggestions rolling in. Thanks,

Jesse

 

I'm not a total idiot. I changed the boot sequence, yet the CD i obtained is not bootable. I need a boot diskette. And, even if those values you have mentioned have changed, I still have the problem of actually getting windows to load in safe or normal mode to modify the settings that might be causing conflict.

 

Thanks for the help and sorry if i insinuated that you were calling me an idiot. Hopefully using the boots will allow me to reformat and/or repair. Thanks again,

Jesse

 

Here's a another question. How do you go about finding out the administrator password? The computer was purchased at auction, therefore I have no way of knowing what the admin password is.

 

Yes it was set and a random doesn't allow access. I will try a installation repair and then if nothing else, try a reformat.

 

If you have any USB devices hooked up try removing them and see if it boots.

No usb devices attatched. No boot.

 

What brand of computer is it?

Steve

 

Custom Build.

1.3 Athlon Thunderbird
asus a7n 266 mobo
256 pc 2100 ddr ram

 

OK. I thought F11 or F2 might help on boot, but if it's a custom I doubt it.

No, the good ole' delete key accesses the BIOS in this case.
