I just bought a Graphic Card Upgrade Kit NVIDIA GeForce 8800GT for 1. Gen. Mac Pro (MB560Z/A).
Now I have a 1. Gen. Mac Pro (MacPro 1.1 from January 2007 with bus spedd 1.33 GHz) under MacOs 10.5.8. So it is the right Upgrade Kit. But the graphic card does not work in my Mac Pro. When the card is built in the MacPro including the power cable and the display is connected the MacPro does not start. Only the startup chime is to hear - infinitely.
Does anyone know how I can solve this problem and bring the card in working ???
Thank you
