Use normal old dvi cable to display instead of hdmi if you didn't. You sd see at least smthng
there, otherwise check with old graphics card. Hdmi needs drivers and can be used after they are installed. Is there anything between processor and mobo, ie. thermal grease. Windows will need drivers for new hw, so sd be connected to net.
I had similar problem with new Ati system, after cable change I could see error message from mobo on screen: processor overheated. Standard Intel was not enough. More efficient propeller and game started.
