When I put In The Card the fan spins but my screen says black.
But when i plug in my on board gfx card it works

Have you bought the HD 3870 and replaced another card ? or was it in your system and it suddenly it happened ?

Make sure you connected monitor cable behind the Gfx card.
Like you connect it to motherboard when you run onboard.

Try the 3870 is another system. The card might be dead. The fan can still on a dead card without the card putting out a signal.

Maybe you have option in BIOS where you can selecet 1st display as PCI-E.
