I have an 08 mac pro I bought 4 weeks ago. I shut it down today, and when I tried to turn it back on, blank screen ! So, I got it to boot once in safe mode but it was completely random and just gave me a few more black screens. I tried another display and nothing. So i booted from the DVD and reinstalled the OS through the 'archive and install' method. All was working fine until I decided to restart to see if my issues were resolved. Now, when I turn it on, I get to the apple logo (although it has stopped giving me the startup sound) and a progress bar begins loading, and stops about 3 or 4 notches from the end. The mac thinks a bit and makes some noise, but nothing happens, it stays like that. Please someone tell me there's a quick fix for this and it's a common issue ! The only thing I can think of is that the graphics card is dead, since it's the one I got with it and I believe it's not very good, especially since I've probably been pushing it with some games, but if that was the issue, nothing would show on my screen would it ? Can anyone please help me out ? I really appreciate any replies. Thanks, karl.
