Hi, I have a white macbook () has the following problems: 1. When closing the lid or pressing the power button the computer freezes, the fans start spinning fast it stays like that until it drains the battery. This happens every time. 2. Start-up times are very long, like 3 or 4 minutes. This also happens every time. 3. Now after a fresh snow leopard install it doesn't even start up completely, as it stays showing a light blue background and I can hear the music of the introductory animation. 4. Also, the keyboard is unresponsive at the login screen, but the mouse cursor moves and the display goes to sleep normally. Clicking anywhere with the mouse also produces no effect. 5. It seems to work OK in safe mode. The macbook worked ok with the factory installed Tiger. The SL DVD is OK, as its installation has been tested on another Mac. The machine's advanced hardware test passed successfully. Resetting Pram and SMC did not solve the problem. I don't know what else to do... please help.
