Title says it all. My computer was installing 55 windows updates and then the screen went black and stayed black for 5 or so minutes so i held the power button down until it shut off. When i went to turn it back on the tower turns on fine the power button lights up and the fans are running but the monitor stays asleep and wont turn on. I have tryed using 3 different monitors and two different cords and still no luck.

If you are comfortable opening your computer up check to see that the video card is seated, assuming its not integrated. What is your computer model/specs?
