    Hey guys, I have a 3 year old Macbook that has been running perfectly until today. Today while browsing, the screen just turned black so I held down the power button to restart it. When it booted up again, it only lasted probably a minute or 2 and then it restarted by itself. Now when I boot my computer up, it does not even go to the login screen. I can hear the drives spinning and there is battery left. I have not experimented with putting in the Leopard boot disk yet.

    By the way, I installed a new harddrive and some ram that was not from apple. I dunno if this makes a difference but I just thought I'd add that. I have done many searches and have not found anything similiar to this nature. Thank you in advanced.

    I just tried to take out a dvd disk. That seemed like it worked because it let me go to the log in screen and I was able to log in. A couple minutes after, the screen turned black and it seemed to restart itself. The link for safe mode did not work...

    Sounds like a failing logic board.

    How do I check if it really is the logic board?

    You really cannot. The only way is to take it to the Apple Store and have them run diagnostics on the machine.

    Is it something they can run in the store? Or is it something they have to send in?

    They can run it in store. It only takes a few minutes.

    Alright thanks for your help. I'm going to try and reformat and see if the problem still happens.. or if it even let's me do it.
