i have recently been doing some things to my system as in this faq i found at http://www.index-site.com/Macosxspeed.html to "speed up OS X". and then not long after, i tried to move something out of my trash, and the finder locked up, my icons dissapeared, and it kept restarting! I rebooted my machine and the problem persists. it tries to run, freezes, not responds, then restarts. meanwhile, i can only get into programs that are on my dock. i restarted, typed cmd-s, then fsck -f, and there were no problems there. I put my osx panther install disc in, to try to do an archive & install(to reset prefrences) however i do not know how to get it to run, because i can't use my finder. I do not know what i'm doing on a mac. please explain very detailed how i can fix this-- thank you!!
