    What is the brand and model of computer or motherboard.
    It could be that your AGP video graphics card has either gone bad, or has lost the drivers.
    A simple test is to cold boot to SAFE MODE. The default Microsoft VGA driver is used for display at 640 x 480 resolution and in 16 colors. You must log on in all modes by a domain or by the local Security Accounts Manager, depending on which Safe Boot mode you select., by pressing the <F8> key repeatedly once per second

    1. Restart your computer and start pressing the F8 key on your keyboard. On a computer that is configured for booting to multiple operating systems, you can press the F8 key when the Boot Menu appears.
    2. Select an option when the Windows Advanced Options menu appears, and then press ENTER.
    3. When the Boot menu appears again, and the words "Safe Mode" appear in blue at the bottom, select the installation that you want to start, and then press ENTER.

    Then, if it works in low resolution, go back and try again using this option as a test:

    • Enable VGA Mode: This option starts Windows in 640 x 480 mode by using the current video driver (not Vga.sys). This mode is useful if the display is configured for a setting that the monitor cannot display.

    or try this option
    • Enable Boot Logging: This option turns on logging when the computer is started with any of the Safe Boot options except Last Known Good Configuration. The Boot Logging text is recorded in the Ntbtlog.txt file in the %SystemRoot% folder.
