If a service or device driver is started automatically and is incompatible with the current version of Windows, the service or device driver may not allow Windows to remain running long enough for you to shut down the service or disable the outdated device driver.

This behavior can occur if hardware or software is installed that installs a device drivers, software or service that is incompatible with the current version of Windows XP that you might be using. Its better in such case to disable those drivers and services as mention by Solomon.

1. Start your computer with the Windows boot disks, or with the Windows CD-ROM if your computer supports booting from the CD-ROM drive.
2. When the Welcome to Setup dialog box is displayed, press R to repair, and then press C to start Recovery Console.
3. Choose to install Windows and log on to your computer with the Administrator account.
4. From the %SystemRoot%\System32 folder at the command prompt, type listsvc, and then press ENTER.
5. Locate the service or driver that is causing the problem in the list that is provided.
NOTE: Selecting the wrong service or device could cause further problems.
6. Type disable servicename (where servicename is the name of the service), and then press ENTER.

NOTE: The disable command prints the old start_type of the service before resetting it to SERVICE_DISABLED. You should record the old start_type, in case you need to re-enable the service.
7. Type exit, and the computer restarts automatically. Allow the computer to boot normally.
