>Book boots to a blank screen no icon's after a few minutes it freezes up. >ANY IDEAS? Help please if you can. Have you tried the following, when you can't get anything other than a black screen & freeze? -hold "Option" key down while starting up (if you have some sort of startup CD *already* in the computer, hold "Option" and "Mouse") -you will get a bright blue screen; still holding the keys, -insert a startup CD (if it isn't already in there); soon, you will see only two icons-- not the usual screen at all. -Wait for the "watch" to become an "arrow" (this is a "curly" arrow on the left of your screen)--it will give you the choice of starting from HD or the inserted disk--click the CD/disk option, and then the "straight" arrow; voila, it should start up/load just fine. -now, you are ready to do your repair & checking :>)
