|Might be a refresh rate issue.|
Try tapping F8 during boot and starting Windows via Safe Mode. Then go to Display Properties > Settings tab > Advanced button > Monitor tab.
Typically Screen refresh rate will be around 60 to 70 Herts. Depending upon what you find, you could try settings a little either side of these figures. Better still set it to whatever is specified for your laptop screen.
The reason I suggested Safe Mode is because presumably you can't read the normal screen.
