About a week ago my MBP seemed to be running slow so I decided to restart it. It refused to properly boot up, though. It seemed to be booting fine (if, maybe, a bit slow) till after I logged in. My background loaded, as did my desktop icons (aside from the Macintosh HD icon, but the text loaded), but nothing would open and I couldn't open any finder windows. The problem has remained essentially the same, changing slightly at times, but it is still essentially identical. There was a period when nothing loaded, not even my background, but that passed. Currently, it sort of varies between loading everything but the menu bar and loading everything but the Macintosh HD icon. I can't open anything, and external harddrives refuse to show up. However, when I unplug external hdd's I get the standard "You removed something without ejecting it" message. I have tried to boot from my Leopard disk, but to no avail; the disk spins, there is a clicking sound from the drive and then it's ejected. The same happens when I put a disk in after I've logged in. I have also tried using different ram and resetting the PMU, but to no avail. Any advice or suggestions would be greatly appreciated, I really need to be able to use my computer and access the data on it. Bringing it to an Apple Store isn't really an option because I'm at my college and the closest Apple Store is 40 minutes away, and I don't have a car. Thanks.
