I've few computers where they will not boot accurately after I've installed the Windows XP Service Pack 3 on them. After finishing the installation then the computer prompts for a reboot. The computer will then start to reboot and may give a BSOD Stop Error for a second and then reboot it again. This process will carry on except the computer is been started in Safe Mode. In Safe mode the computer will boot accurately and all the things seems to be working fine. This type of problem will appear only on some of the systems after upgrading it to the SP3. This kind of problem on the systems which are been produced with the SysPrep. The sysprep image which has been produced on an Intel based computer, and then provide with the sysprep image is also installed on a Non-Intel system like an AMD processor. In these cases, the registry entry for Intelppm is also incorrect set and can lead the computer to go into a nonstop reboot after the service pack has been installed in it.
