my idiot friend was playing with my wall switches and he turned of my dual 2 ghz rev a. g5 while i was doing some heavy hard drive work. since then it has been acting very odd, freezing up and such. (also preview seems to be affected somehow its just acting plain weird) is there anything short of a reinstall of 10.3 that i can do to repair my maybe messed up disk? or is it not even a disk problem? thanks guys.
