Hello, have an extremely strange issue. I have a Mac Pro 1,1 with two displays and an NVIDIA 8800 card. I was booted into Windows 7 using bootcamp, the machine froze during video playback, hard rebooted. Blue Screened in Windows, went to restart into OS 10.5.7 and I get the Apple logo and spinning gear, it then flashes briefly and goes to a grey screen. The second monitor never engages. The machine is fully booted as I can connect to it with my laptop through filesharing. I've tried PRAM/SMC reset, removing all the RAM/all external devices, pretty much everything. Anyone seen anything like this? I've even tried replacing the video card and switching PCI slots, with the same issue still occurring. Any other ideas?
