During researching #2, I found several articles mentioning Windows Updates that are including files compatible with Windows Vista and Windows 7, but that have issue with Windows XP Service Pack 2. In fact, they referred to it as XP's SP2 having a bug that is causing the trouble.

Here is the simple fix used on these last two: (budget a little over an hour to complete if SP3 is on hand)

• Boot to Safe Mode
• Use MSconfig to disable all SQL services and Outlook's Business Contact Manager
• Boot normally
• Install Service Pack 3 for Windows XP and reboot
• Enable services and reboot again

This information was listed on the BSOD after disabling automatic reboot:
Stop: 0xC000021A
Stop: 0xC0000005 (0x7C9101B3, 0X0069EC24)

This information is listed in the Event Log just prior to the crash/reboot cycling:
