Hi, My mac crashed while playing Modern Warfare 2 (via Bootcamp) - I restarted in OSX only to find it froze and this happened: http://twitpic.com/rzcgh I've managed to back up my HD. And have formatted it via Firewire from a Macbook. But I'm still getting the strange lines and I still can't boot. But not it won't even boot, before it crashes at startup I see this. http://twitpic.com/s3gge I've tried booting with a DVD. Installing OSX using the Macbook via firewire, resetting PRAM, booting in safe mode etc... Nothing works. I guess really I'd like to know what your guesses are at what might be causing this. Thanks.
