I have a 2 week old MP and have had 4 incidents in that periode were I just get a grey screen when trying to turn it on. I have to try up to 6 times to start it. It always turn in the end (so far) We are in the middle of editing the 2. out of 4 30min TV programs so I can´t afford to send it back, nor can i afford it not to start up one day. Also, when I put it to sleep over night it has usually shut down when I arrive in the morning. We run FCP on it and have installed 2 internal HDs, Seagate Barrracudas. Any idea of what causes this? Any solutions?
