Bluescreened only at shutdown/reboot - help anyone?

[Guest Tony Meloche]

This happens about 2 times out of three when shutting down or rebooting.

I'm enclosing all teh relevant data I can think of. Here's what you

should know first of all:

 

The computer boots up and runs perfectly. No problems of any kind with

anything from boot until shutdown or reboot, whether five minutes or

five hours later.

 

Avast Professional, up to date thorough scan - clean.

 

Four different well-respected anti-malware tools, all current on

updates, full scans - nada.

 

Event log, any category: Nothing out of the ordinary.

 

I AM running UPH clean.

 

This is the bluescreen I get. On *normal* shutdown or reboot, first the

icons disappear from the desktop, then the "Windows Blue" screens:

Saving your settings, shutting down, etc. On the bluescreen shut down

or reboot, the icons disappear, then the blank desktop pauses for a

moment, then black - the bluescreen comes up with this info"

 

Fatal Error - LOGIN process system C000021A (note I am *shutting down*

at the time! Login??)

 

 

 

Status of

 

(0x 00000000 0x00000000)

 

About a third of the time, it shuts down perfectly normally. I can boot

fine, I can use my computer perfectly normally, but this is a problem -

no bluescreen is good - can anyone help?

 

Thanks!

 

Tony

Background information on Stop Error message

http://msdn2.microsoft.com/en-us/library/ms797159.aspx

 

0xC000021A: STATUS_SYSTEM_PROCESS_TERMINATED

This occurs when Windows switches into kernel mode and a user-mode

subsystem, such as Winlogon or the Client Server Runtime Subsystem

(CSRSS), is compromised. Security can no longer be guaranteed. Because

Win XP can't run without Winlogon or CSRSS, this is one of the few

situations where the failure of a user-mode service can cause the system

to stop responding. This Stop message also can occur as a result of

malware infestation or when the computer is restarted after a system

administrator has modified permissions so that the SYSTEM account no

longer has adequate permissions to access system files and folders.

Thanks, Gerry - I got a lot of info from that site that helped in

understanding the problem, though none of it seemed to apply directly to

my situation. I was able to recover by using System Restore from last

Friday - day before the problem started (I wanted to see if there were

other alternatives first). But I appreciate the info, and have

bookmarked that site.

Thanks JS - I deleted and scrubbed "everything Norton" some months ago,

including GoBack. I was able to solve the problem using System Restore,

but I wanted to see if there were other alternatives first, but nothing

I looked up or consulted for here applied directly to my situation.

Frankly, I wondered if SysRestore would fix it, but it did.

 

Have made no noteworthy changes to my computer since Friday (downloads,

etc.) nor changed settings, so I will just have to wonder what caused

it. But thankfully, all seems well again now.

Glad to here all is well.

Most (but not all) of System Restore's capability is putting the registry

back to were it was at the point in time the restore point was created.
