Blue Screen error message Stop: c000021a {Fatal System Error}

 I'm unable to get my computer past the Windows XP screen without a blue screen, keeps rebooting.

I was able to get to the Windows Advanced Options Menue and was able to "Disable automatic restart on system failure" to get the entire error message.
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.

Twice I was able to get to "Safe Mode", words ran across the screen like they normally will do when in "Safe Mode", but both times the computer restarted again.

I tried running a repair multiple times with a borrowed Windows XP disc, each time after the repair it said that the system had errors but had been repaired, but the problem continues, computer just keeps rebooting, shutting down with the error message again in a loop.  Hopefully this helps.


chkdsk c: /p only detects errors, I ran that command prior to asking for help on this site. . .but as an update. . .I contacted Microsoft since the problem was related to an update. . .I received a new operating system CD, went through the same repair with the new CD with Microsoft. . . Spoke to five different people. . .three different phone calls. . .ended up at square one. . . BSOD. . .But I don't quit easily. . .I went back into my DOS screen. . .and was able to finally repair the operating system. . .The  problem was due to the repair CD having IE6 installed which over-wrote my IE9. . .which caused confusion in the boot-up.. .which continued the computer not being able to recognize the Windows Explorer. . .etc. etc. etc.   

Nine days later. . .I'm back up and running. . .Whew!!

Thanks for trying to assist. . .

I work on 10-20 computers a week. . .This one was a tough one. . .
