The PCI Bus Driver service is a kernel driver. If the PCI Bus Driver fails to load or initialize, the error is logged and the computer attempts to restart with the LastKnownGood configuration. If the LastKnownGood configuration fails, Windows XP startup also fails, and the boot process halts with a Stop error. If you disable this service, Windows XP will fail to start. Do NOT change this service startup configuration if your computer is working.
