解决方案

INTEL集成显卡(NAPA平台)有两种控制显示方法:系统直接控制和驱动控制

WINDOWS启动时由系统直接控制启动后半程开始加载驱动在加载驱动过程中会有水平的白色亮线闪烁.

这种情况是显示卡驱动初始化时的正常现象并不代表产品有质量问题.

Intel's integrated graphics chipset (Napa) which has two ways to control the video:

Operating system direct control.
Video driver control.

While Vista is booting the operating system will use its own built in process to control the video output. As the operating system is booting it will initiate the video driver and transfer control of the video output to the Intel video driver. When the video device is initialized user may observe several white lines flashing across the screen for a moment.
