I'm having a problem with my macbook pro (2008) not booting up and maybe someone can help.
One day it just stopped booting...totally dead...so I'm guessing there is a motherboard failure..

When I press the on/off button (on battery / on charger), nothing seems to happen.
Iíve checked memory/hdd but no problem there..

When I disassembled the notebook, I noticed that when pressing the on/off switch the fans try to spin but they don't (again and again)

Is there a way to be sure it's the motherboard and not something else Iím missing?
