Hi everyone, this is my first post here on MacRumors. My macbook pro 2008 won't start up at all. Here's what happens. -I press the power button, fan, LED, and harddrive noises for about one 1 second, then my computer totally shuts down -I press the power button for 10 seconds, fan, LED, and harddrive noises for a longer time, then computer shuts down again I did a recent RAM change, however, my computer booted up completely right and never had any problems until maybe 2 months later. When I take out the RAM (no RAM in the computer) I get a long beep (only one). I went to a local computer store and they told me that the logic board was dead, however, they only took 10 seconds to look at the computer. Thanks for all your help!
