hey i got a power mac g4 that is running tiger, i mabe got it about 3 to 4 months ago. I got it upgraded just about a month ago by a guy that has worked on them for years. so he instaled the latest things for tiger, including the combo pack. so i tried to install the update, i didn't know that he had already put the combo update on it. so i installed it then it recomended me of course to restart the mac, so i did. then, when it booted up, it only made it to the apple logo screen and thats it. the spiral that spins didn't even come up. i was sitting there for at least five minutes. i forced it to reset, i held the power button to turn it off , then turned it back on. i unpluged all my stuff, i tried every keyboard shortcut almost. so i know the last option is to reinstall tiger back on my power mac g4 by putting the disk in then holding c at startup. so i wanted to ask, if i reinstall tiger, wont it get rid of my music files, and all my applications that were installed that didn't come with tiger?
