ok it started when i broke my laptops screen. i connected it to a external moniter and it worked. a month later my hdd was full so i completely erased it and load a brand new copy of win 7 ultimate. after it reboot thats where the problem happened. i connect my external moniter and it doesn't show. i tried everything like start and p and also fn f4. it doesnt work. i know my computer is on because i hear the sound it makes when it says welcome also hear skype pop up so my computer works but i cant see anything on my external screen. please someone tell me how to make the external screen to work.
thanks
