WinXP Pro SP3.

When I plugged in the second monitor the system would not recognize.
and got BSD.

A problem has been detected and Windows has been shut down to prevent damage
to your computer.

The problem seems to be caused by the following file: win32k.sys

VIDEO_DRIVER_INIT_FAILURE

Technical Information:

cabling is DVI for the two monitors.
The original screen stayed blank. The second screen gave the BSD.
