2 Mac Pro won't boot at all.
When I press the button everything comes on, fans, lights, chime, but the screen stays black as if it was off. Could it be the HDD? the graphics card is working, but not sure if its working right.

Why do you think the graphics card is working?

It does have a fan that works every time I turn it on, but like I said I'm not sure if it's working right or if it's really working.
