Hey guys I have no idea why but all of a sudden last night my computer shut off by itself while being idle. I turned it back on and it would turn on, but once it got to the stage where it needed to load the OS (I dual boot OSX and W7 Ultimate) it shut off. This happened a couple of more times so I shut off the power on my power bar and turned it back on. After that nothing period happens when I press the power button. The fact that it booted up to a certain point before leads me to believe that it might possibly be the motherboard as well, but I'm not completely sure. I'm currently at work and won't be home for another little while and I just thought I'd have others weigh in on all this. What do you guys think?
