I'm experiencing weirdness with my iMac and this is a first for me. I normally watch a movie via Front Row and fall asleep to it for whatever that's worth. Well, yesterday morning I woke up and the screen was black so I rebooted it several times and it came back on. I used the computer throughout the day and didn't experience any problems. This morning I wake up and the screen is black again but *this* time I can't seem to get anything to display despite a number of reboots! It is an Intel based milky white iMac. The glowing light in the lower right of the bezel is glowing steady. Help!!!!
