Here are some references for you to review.
See the Aumha page on Windows 5x Stop codes. Scroll down to section on 000000D1 (look for "D1" link on right-hand pane)

For your consideration.
A useful set of tips from Joshua Smith at MSFT:
<begin quote>
To determine what driver is causing the problem I need you to enable driver verifier.
Steps:
1) Windows Key + R
2) Type in 'verifier' and hit enter
3) Make sure 'Create Standard Setting' is selected and hit next
4) Click on 'Select all drivers installed on this computer' and hit Finish
5) Reboot
There is a possibility that your computer will crash on reboot. If this
occurs hit F8 when rebooting just before the windows logo screen and select
the safe mode boot option. Follow the same steps above but on step 4 choose
'Select driver names from a list'; hit next; check the box next to any
driver where the provider is not Microsoft; hit Finish; reboot.
This will slow the performance of you computer a little while enabled but will hopefully catch the driver causing corruption. Next time you crash the blue screen will hopefully say something like
"DRIVER_VERIFIER_DETECTED_VIOLÂÂATION".
