I have a 2006 Macbook that i received from a friend. It seems that it will not boot. When it is turned on you can hear the boot sound and it comes to a grey screen and just sits there. There is no apple logo or anything, just a blank grey screen. Have tried booting with no HDD and still the same issue. Also tried to switch RAM slots with no success. What can i do now to fix this laptop? I have tried the Pram reset as well as anything else i could find online and nothing will get me past this blank grey screen. I dont care about the data on the drive either.
