i bought a new ibook in october of 2004. just days ago the cursor froze for the first time--i had to hard-shut-down. upon reboot after being completely shut off, 7 out of ten times it doesn't even make it to the desktop--it freezes at the blue screen that appears before the desktop. if it does make it to the desktop, it freezes shortly thereafter, and NEVER gets past the blue screen if i just restart (command + eject). i've run both the hardware test and the software test from the disk-one CD-ROM provided by Apple, and both tests came back with no problems detected. i have 16 MB of free space. does anyone have any ideas of the problems or what i can do?
