Video card problem

Please help

My pc had an nvs 285 and everything worked fine.

But when i put in my radeon 5770, the fans spin and everything but no image on the screen. Also no beeps either.

I have tried using 2 power supplies (on for the gpu) as well but no luck.

My pc is a intellisation m pro if that helps.

Thanks guys
