whenever I plug my monitor onto the onboard video plug on the back of the PC.. nothing displays.. but when I put it into my secondary graphics display plug (both blue plugs.. if you are familiar with the Dell).. it works just fine.. I went into System Setup and changed the primary video to onboard video and it still does the same thing.. it was never like this before.. it was working just fine before I unplugged and replugged everything back. And I've double and triple checked.. it's the same as before.. any clue?
