At around the 75% mark of the WIN 10 install this evening, one of my dual monitors erupted in horizontal rainbow strobe lights. Did a hard reboot with the same result. Did I download the driver for the 4400 released yesterday prior to install? Of course not. Since this is my Admin PC for my business, I need this fixed 3 hours ago. Any and all help/advice would be very much appreciated. 

Hi,

I have noticed that the new Intel Graphics driver for Window 10 is available now. Please download it from the following address and try again.

In addition, I would like to suggest you connect one monitor during the installation.
