Can you go back to the old graphics card?
Does it happen when booting up now or just when watching movies?
Is there an extra place for power to be plugged into the card?

I've had that happen before. The problem was the card required extra power to run the onboard fan. My power supply did not have the right input to plug into the card so it would work but as soon as the card was over heated - game or movie - then blue screen.
