I MOVED MY COMPUTER TO CLEAN AFTER THAN I START MY COMPUTER I SAW MY MONITOR IN BLUE. I SAW EVERYTHING BUT EVERYTHING WAS IN BLUE. I CHECKED MY MONITOR CABLE BUT NOTHING HAPPEN. I CONNECT MY COMPUTER TO ANOTHER CPU IT WORKS ON THAT. I THINK PROBLEM IS IN CPU PLZ GIVE ANY SUGGESTIONS.

mmm... Your computer worked OK then you moved it and now it doesn't? Clarify/confirm - you connected the monitor to another PC and that computer (PC) worked OK with the monitor. When you conenct your first PC (computer) to another monitor it workd OK - or did not work OK? The blue screen you get when your (first) computer boots up - does it have writing on it - lines of text etc.?

Check the video connector for a bent/broken pin. If pin #1 is broken, it will cause a bluish screen. If the connector is ok, and you have a video 'card', try reseating the card.
