When you start your computer, you may see a blank screen
with a white dot in the upper-left corner of the screen.
This issue may occur if you are using an Accelerated Graphic
Port (AGP) video adapter but your AGP slot has not been configured to accept
the video adapter.
To resolve this problem:NOTE
: To complete the following steps, you must have a Peripheral
Component Interconnect (PCI) video adapter.WARNING
: Internal computer components may be damaged by static
electricty, use of too much force for removal or insertion, or the use of
inappropriate tools. If you are not very familiar with computer hardware
installation, Microsoft recommends that you contact a qualified technician for
repair of internal computer components.
- Shut down your computer, and then unplug it from the wall
- Open your computer case, and then remove the AGP video
- Insert the PCI video adapter card into the first available
- IMPORTANT: You may have to change your computer BIOS in this step. Do not
do so unless you are very familiar with BIOS changes.
Make sure that
your computer BIOS is configured to use the PCI video adapter before the AGP
video adapter. You may have to change the VGA BIOS sequence (PCI/AGP) in your
computer BIOS. When you do this, you change the video adapter that is used as
the primary video adapter. The PCI bus is typically enumerated before the AGP
bus. Because of this, the PCI video adapter is designated as the primary video
adapter. For more information about how to change the VGA BIOS sequence,
contact your computer manufacturer or read your computer documentation.
For information about how to
contact your computer manufacturer, visit the following Web site:
- After you start your computer, obtain and install Windows
XP-compatible drivers for your AGP video adapter. For information about how to
do so, read your video adapter documentation, or contact the manufacturer of
your video adapter. After you have configured the AGP video adapter, you can
safely remove the PCI video adapter.
