Death of an OS

I've been trying to salvage a Windows XP laptop which mysteriously blue screened the other day. Ever since, when it boots, right after the XP load screen, it blue screens again with this error:

STOP: c000021a {Fatal System Error}
The Session Manager Initialization system process terminated unexpectedly with a
 status of 0xc000026c (0x00000000 0x00000000).
The system has been shut down.

Looking up the error via Google doesn't give me any useful results other than "reinstall XP", so, I've been using a LiveCD to move all of the essential data (music, documents, Firefox settings, etc.) to another computer. It's a very fun process.
