I came out of sleep on my new mac pro today and it wouldn't get any video (it has dual 8800GTs connected to three 30" monitors). I thought maybe it was a sleep glitch so I rebooted thinking nothing of it. Upon reboot same problem except now the fans are going full speed and not stopping. So I reboot again and this time the fans calm down but I get a screen that says I must shut down or reboot the Mac Pro. I tried this a few times and eventually I stopped getting this screen and only get the black screen. If I take out the second 8800GT everything works perfectly fine like it did before, but I tried putting it back in and it is exactly the same.... so much for quality parts hehe.. haven't had this happen with one of my built PCs so far in over 10 years... so I'm really not sure what to do. Do I just call Apple and tell them the video card is dead and they ship me a new one? Or am I going to have to go through some big run around? Are they going to try to scam me and not warranty it since it is a part and not a system? Thanks!
