Whenever my brother turns on his mbp it won't go past the blue screen with the apple and the loading gear. I think it is due to not upgrading his software, but any suggestions on how to get it to start up would be a big help!
I had that problem, actually, not too long ago... I had to reinstall my OS...
insert the original OSX CD and hold down the C key...... boot from the CD and do a disk utility and check your disk for errors. It might fix the problem and if it doesn't... reinstall the OS.
I HAD to reinstall.... once I booted from the CD and did the disk utility, it attempted to fix 3 times and failed... I had some bad sectors or something... my post about it is in here somewhere...
