The screen is black when you start Win7:

Solution:  This panic inducing problem is often attributed to minor problems with your graphics Card or the cable that connects it to the monitor. First, check that your monitor is plugged into A power socket and that the monitor cable (either Video Graphics Array (VGA) or Digital Visual Interface (DVI)) is firmly connected to both the monitor and your computer's graphics Port. If the monitor flickers when moving the cable, there might be a problem with the cable Itself, so try a replacement cable if you have one.
