So I have had this macbook since 07 and it's had somewhat of a difficult life. It used to overheat quite often and shut down randomly so I used smcfancontrol to help with that. For the past year it has been fine...until now. Just recently I closed my macbook and then, when I reopened it, it wouldn't come to life again. I held down the power button to turn it off which it did. It hasn't turned back on since. When i press the power button the screen flashes white and then goes black again. I can hear the computer try to start up for about 5 seconds and then the hard drive clicks once and it all powers down. the white LED in front never comes on during any of this. When i take out the ram and try to turn it on the same thing happens so maybe it means that the ram is bad? maybe someone can help.
