RESOLUTION
To resolve this issue, disable the
Agp440.sys service:
IMPORTANT: You must know the
administrator password to complete the following procedure. If you
do not know the administrator password, contact your system
administrator. After you complete this procedure, any video adapter
driver you have installed will be disabled, and Windows XP will use
default VGA drivers.

Insert the Windows XP installation
CD-ROM, and then restart your computer. |
| 2. |
When the computer starts, press
F12. |
| 3. |
Start your computer from CD-ROM,
and make sure that you select the drive that contains the
Windows XP installation CD-ROM. |
| 4. |
In the Microsoft Windows Recovery
Console, select R for repair, and then press
ENTER. |
| 5. |
Select the installation number for
the problem installation. |
| 6. |
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. |
| 7. |

Make sure that the Agp440 service
is listed, and that the startup type is set to
"Boot". |

Type disable
agp440, and then press ENTER. |

registry setting for this service was found, and that its
current startup state is
"service_disabled". |
| 12. |
Type exit, and then press
ENTER. |
| 13. |
If you are prompted to start in
Safe mode or Normal mode, start in Normal mode. |
| 14. |
Log on to your
computer. | Windows XP
includes default video drivers that make it possible for your
monitor to work. However, some features may not work as you expect
with these default drivers. Update your video drivers periodically.
To do so, visit your computer manufacturers Web site, and download
the most recent drivers for your video adapter.
