My 5870 Upgrade kit on a 2008 Mac Pro wont work

[marker227]

I just got my 5870 and tried installing it... It won't work with my computer....

I hooked up both power supply cables and installed the card in the bottom slot.. It turns on and everything with the computer, but nothing comes up on my display.

I have a DVI HannsG 28" monitor..

Any ideas why?

I also tried plugging in my Acer monitor... Still no good... I even switched the power supply connects...

The card might be bad.

Fixed it... Not sure what I did, but it's working...
