Addendum to original message: I thought this was only a problem when the computer was in sleep mode. Last night I shut down the computer. This morning the computer monitor would not turn on after starting. I shut down the computer holding in the power button. I started it again ten minutes later and everything was fine.
Have a Mac Pro 2007 with a Cinema Display. Recently after a sleep cycle the screen will not start up. If I force quit the computer and IMMEDIATELY restart it the screen will not start. If I keep the computer off for 10 or 15 minutes everything start. You would think that the video card is going bad but I'm not sure it is this because I can play World of Warcraft for hours and the screen is always on. I keep the fan and fins clean on the card so it doesn't overheat. Any idea why this happens after sleep and how do I fix it?
