Hi all I hope you can help me. I have a MacBook C2D 2GHz, 4gigs of ram from mid 2007. It has snow leo v. 10.6.4. I cant remember when the problem appeared but maybe 6 months ago. Every time the mac is rebootet or shutdown the screen goes black the sleep light stays on but I can hear the chime and cd drive make shot start up sound. After a normal boot up time the screen comes on but its all white/greyish with a black stripe down in the right side and stays like this. If i hold down the power button to power off at hit it again the same thing happens. The way I fix it is to power off, take out the battery for about 10 sec. put it back in and hold two fingers on the trackpad and power on, and it works, but this time today it took me 7 atempts before it worked. I live in denmark so the macstores aren't around the corner. Before I take it all the way to a macstore and have them look at it, do you guys have some thoughts on it?
