This issue may occur if Windows XP tries to use an incompatible motherboard chipset video driver during startup. You will need to do the following:
1. Insert your Windows XP CD-ROM into the computer CD-ROM drive or DVD-ROM drive, and then restart your computer from the CD-ROM.
Note Some computers may require that you modify the basic input/output system (BIOS) settings before you can start the computer from a CD-ROM. For information about how to modify the BIOS, see your computer documentation.
2. At the Welcome to Setup screen, press R to start the Recovery Console.
3. Press the number key that corresponds to the installation that you want to repair, and then press ENTER.
4. Type the password for the administrator account of that installation, and then press ENTER. You receive a drive:WINDOWS> prompt, where drive is the drive on which Windows XP is installed.
5. Type listsvc, and then press ENTER.
6. Make sure that the Agp440 service is listed, and that the startup type is set to "Boot".
7. Press ESC.
8. Type disable agp440, and then press ENTER.
9. You receive a message that the registry setting for this service was found, and that its current startup state is "service_disabled".
10. Type exit, and then press ENTER.
11. If you are prompted to start in Safe mode or Normal mode, start in Normal mode.
12. Log on to your computer.
Your graphic card should boot up properly now:)
