Hey, Just a quick explanation. I'm really down and angry and being forced to use Vista for now -_- I opened up my mac mini to upgrade RAM. I look at it and realised. WTF do I do? So I closed it up again, with the intent to look up instructions on it. When i put it back together, the white light starts, i cant hear anything and after 5 seconds it will go off. and will NOT start up. help?
