As for the random Grey Screen of Deaths, see: http://forums.macrumors.com/showthread.php?t=845811 I am wondering if it is enough to wipe the HD (and if that is the solution, how do I even do that. I'm very bad with computers), or do I have to replace it? If i have to replace the HD, How do i do that? Pricerange for a HD? I honestly don't need any more than 200. I won't ever. Is there a better way to fix it? Thanks in advance.
