I am trying to upgrade the hard drive in my system which currently running Windows 7 and has:
          EVGA GTX 480 video card,
and
          Nvidia SLI mother board.

After replacing my HD with a new one, the screen/video goes fully dark after reboot and nothing appears on the screen (NO video)!
My final plan is to install Win 10 on this new 1TB SSD drive by booting from Win 10 installation DVD.
Any clue how to about such Hard drive upgrade?
(Namely, how to get video after replacing HD.)
