Please help me! I've had my macbook for almost one year and everything has been fine! Until about one month ago that is... My Polyester Unibody macbook (Standard spec) takes between 5 - 10 minutes to boot up (In fact one time it took about an hour!!) the menu bar does not load properly - I.e. no grey semi-transparent bar, no apple logo and the File Edit Window etc. things have gone too. The battery, wifi and time are still there though. Discs usually do not load, programs frequently freeze quit and stop responding, "Force Quit" says there are no programs open (doesn't show any). And finally - the activity monitor tells me all is well, nothing is taking up a considerable amount of memory, nor are there any programs running that aren't the standard processes. (I.e. nothing I've downloaded) Please please PLEASE help me fix this! I've tried reinstalling the operating system with the Mac OS X Install disc but it gets to 35 mins remaining and says "Install Failed". I would really like to come up with a solution that involves me keeping all my files as I have about 500 songs, a film and a few photoshop tools and files, as well as some vital bookmarks and history pages. (Memory is not the issue here, there are over 100gb of free space!) If really necessary I suppose I could wipe it clean. I (think I) backed up my photoshop files and photos, as well as a few other things, to dropbox - the online storage site. And I have my music and film on my iPhone which I think I can retrieve with the help of iPhone Browser..... Any ideas? What could have caused it? Please help... I'm a thorough tech geek and this thing is not only really useful, but also what I use for my part time job!! Thanks. I'm hopeful at least one of you genii can help me out! (I won't be able to get to an apple store for a long time, and I am not risking the post -nor can I afford that).
