Hi - I just joined this forum because my c000021a error seems to be super resilient to any troubleshooting.

I've tried the usual techniques, and nothing works.

Attempting to boot from the XP install disk results in another blue screen near the end of the startup -

"A problem has been detected and Windows has been shut down to prevent damage to your computer.


If this is the first time....(etc.)

Technical information:

*** STOP: 0x0000006F (0xc0000020, 0x00000000, 0x00000000, 0x00000000)"

Is there anything I can do at this point? Is there some software I can buy that will help me out? I'm a mac guy, but this is our family PC.

The error happened when I initiated the Windows repair tool or whatever it's called. Explorer has been a problem (often crashing) and I was hoping naively that a Windows tool would fix a Windows application. Frankly I'm stunned that this tool would bring the computer to it's knees.

Welcome to G2G

Are you able to get Windows to boot (either normally or in safe mode)?
If so, have you tried system restore?

Failing that, if windows doesn't boot, have you tried booting using last known good config?

If that doesn't work, what about recover console?

You said that attempts to boot from the XP install disk resulted in another BSOD. At what point exactly does the BSOD occur?
