I am trying to install 10.6.3 on to my PC. I have a Giga-byte EP45-UD3LR motherboard, 4 GB RAM, and a Diamond ATI 4670 with 1GB DDR. I have tried to used the iBoot Supported cd as well as the iBoot ATI cd. I can boot the install disk and see the gray Apple logo, but when it should be switching to the installed the screen goes black and I no longer get any video. I had my monitor hooked up by DVI and thought maybe the installed only supported VGA, so I swapped cables and rebooted. again the screen went black. Any ideas what I need to do to get this working?
