Info on STOP errors can generally be found at http://www.aumha.org/a/stop.htm:
The process creation failure indicated by this error message can only happen during the fairly brief time that the Windows Executive is being initialized, which is during phase 4 of Windows startup. Typically there is a problem with a device driver or with a missing or corrupt system file used during Windows startup."
