I get to gray screen and it hangs. Can't open dvd drive, Can't Pram it or safe boot. Support coming in a few minutes to see what the issue is... I've noticed some posts here have people getting upgrades when issues like this happens - how to get an upgrade a 2010 MacPro (when it's announced) out of this unfortunate event?? I've had issues with the apple raid card (I know - get rid of it ) and now this. I'm told it could either be a logic board or one of my HDD's... I told the mac 'genius' guy I wasn't happy with this machines performance to which I was told "even if it was a PC, they also have problems" - yeah, but a PC wouldn't cost me USD $6,500!
