The mobo on our PC went kaput, so we got a new one.
I set the BIOS to boot from CD 1st and am using a WinXP Home (the same
OS that's still on the HD.)

Half the time when we try to boot, it locks up after we "Press a key
to boot from CD...." and the other half of the time it goes through
the prep to set up XP, and then blue screens with:

BAD_SYSTEM_CONFIG_INFO
(stuff)
STOP: 0x00000074

(A couple of times it would bluescreen with:
STOP: c0000221 Unknown Hard Error
\SystemRoot\System32\ntdll.dll
Which is kind of odd, because it's booting from the CD not the HD.)

I've tried resetting the BIOS, using Optimal settings, I've used a
different stick of RAM...and all the same thing.

Any ideas??

Thanks!
Liam

Sounds like a faulty Ram module. http://aumha.org/win5/kbestop.htm

I'm hesitant to go that way, because I've tried two different sticks
of RAM with the same blue screens.
Now I get a new bluescreen...
PAGE_FAULT_IN_NONPAGED_AREA

Is there something with the BIOS that might need to be set? I tried
different preset clockspeeds, but no change.

Thanks for any suggestions!
