I am working on an Inspiron 6000 that began crashing with blue screens
(c000021a; stop:0x0000000A; among
others). Hopefully someone out there has experienced a similar problem
and can save me from buying my second
replacement motherboard.

No software or hardware changes were made immediately prior to problem.

Here are the steps I've taken:

I suspected either a corrupt system file or a failing hard drive so I
thought I would start by
running "chkdsk /r" but couldn't get past the first 10 seconds of 6
different XP and Windows
2000 install disks, all factory burned disks.

Replaced DVD drive with two (2) different working CDRom drives from
other machines with the
same result. With Windows XP it consistently stops with the error:

"File \i386\ntkrnlmp.exe could not be loaded.
The error code is 7

Setup cannot continue. Press any key to exit."

Windows 2000 install disk stops with a different error at about the
same point.

I even got a blue screen booting with a BartPE disk after it had fully
loaded (only tried it
once).

Tried pressing F5 to disable ACPI during install with no luck.

Tried disabling everything non-essential in the bios with no luck.

Booted with the keyboard removed and an external keyboard - no joy.

Booted with an external monitor with no luck.

Ran the built-in Dell diagnostics and everything passed including about
12 hours of the memory
tests with the exception of something about the "Real Time Clock 32 bit
crystal" (paraphrasing).

Replaced the (2) 256mb DDR2 memory sticks with (1) 512 DDR2 memory
stick with the same results.

Replaced the motherboard with one purchased on eBay and every single
issue, every single error,
at the exact same points remain as if I never even opened the case.

Maybe worth mentioning: Two different times I reset the bios (once with
each motherboard) to the factory defaults and when I tried booting to
the hard drive immediately after it would take me to the point of
loading the desktop and then crash with the stop:

"stop: c000021a {Fatal System Error}The Windows Logon Process system
process terminated
unexpectedly with a status of 0xc0000005 (0x00000000 0x00000000).The
system has been shut
down."

Any other time I would boot to the hard disk it would crash before or
during the XP logo screen.

The only thing that hasn't been replaced is the processor and the LCD.

Is it possible I got a replacement motherboard with the EXACT same
issues?

Is it my processor (nothing on the processor looks obviously swelled or
damaged)?

Is God punishing me or is there something obvious I'm missing (yes and
maybe?)?

Any help would be greatly appreciated.
