Found it, same thing for XP according to another site. I've never tried, let me know if it works!
Tip #56: Force Windows 2000 Crash
Perhaps they made it too stable? There is a registry entry that you can use to force a blue stop screen on Windows 2000 (hopefully this is because you won't ever see one otherwise). First, backup your registry, then make the following change:
Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Services\i8042prt\Parameters
Name: CrashOnCtrlScroll
Data Type: REG_DWORD
Value: 1 (0 or nothing will disable the feature)
After a restart, holding down the right-side CTRL key and pressing the Scroll lock key twice will generate the Blue Screen of Death.
