I know the title is generic but I'm not totally sure how to describe the problem. Just for background, I have a 2.16 GHz Intel Core Duo Macbook Pro (the first run of MBP's), and I've partitioned the hard drive and installed Windows XP (which is currently functioning perfectly). The problem is on the part with Leopard installed. When I try to boot up my Leopard partition, the desktop shows up, the mouse arrow moves, dock and menu bar are all there, however no applications will launch, no finder windows will open and I'm effectively stuck. If i try to shutdown or restart, the menu bar and desktop items will disappear leaving just the dock indefinitely (often it'll even start to do this on its own after launching). I've tried repairing the disk via disk utility to no effect, and I've tried running the hardware test by holding d as the computer starts up. Each time the screen flashes a bit and just as a window pops up the computer shuts down. The only new things that happened around the time this problem started are I got a new external monitor and started using parallels to run a virtual machine from my boot camp install, though I haven't run it in several days. This problem has been present for about a week, though each time before today it would go to the mode where I was "stuck" during normal use, and often be normal on restart. I do have time machine backups and I'm considering trying an archive and install or erase and install if I have to, unfortunately I don't have my disks, only my roommate's, and he has a newer MBP. I will try to get my disks soon though, so at the worst I can just cut my losses and format the drive. I'm at a complete loss and thought I'd just come here to ask if anyone knew anything I could try.
