Blue screen after logging into adm...

Got a Blue Screen and no desktop icons on Macbook Pro?
You need a second Mac to fix the problem, plus a firewire cable that is firewire at both ends. Connect the affected computer with (Leopard installed) to another Mac.
Restart the affected Mac (blue screen only ) and hold down a "T" on it's keyboard while rebooting to go into target disk mode, The assisting mac will mount an icon on the desktop of the hard drive so you can access the affected one. Open the mounted disk volume (double click the yellow hard drive icon) now you are into the affected computer's drive. Open system folder>Library> and find SystemConfiguration folder.
Locate "ApplicationEnhancer.bundle" drag that to the trash.
Eject volume and restart the original computer, no need to hold down any keys, just reboot and you're good. Source: Apple Macbookbook pro support from Apple website. It worked for me (Thank God!)

Start with OS X cd/dvd. put the cd in and restart, hold down C after you turn the laptop on. when the disk starts up, try to repair the hard drive (verify and repair permissions). I'd also try getting your hands on Disk Warrior, which can fix lots of hard drive problems. You might have to reinstall OS X though if it's bad. If you have to do this, you may want to upgrade the harddrive because that might be what caused the problem in the first place. If you go to repair permissions and it finds problems and repairs them. Try it again. If it finds problems the second time, you may have a bad hard drive. See how my answer is longer than your question. It really helps to provide details and specifics if you want a good answer. just keep that in mind if you reply. thanks. good luck.
