  1. Check if your video card is properly seated, and that you didn't knock it loose or something. Same thing for all your components. Are you able to try starting Windows in safe mode as well?
  2. I have the same problem. I have made sure the graphics cards are sitting properly, and it will start in safe mode. However, when I try booting it normally, the screen goes black when it tries to load the os (windows)
