It started when everytime I loaded up safari and tried to open a page and safari would just quit unexpectedly, with no "reopen" "close" or "report" option it would just close. I also noticed the finder repedidly reloading. It also wouldn't let me shut down so I turned it off manually. When attempting to re-boot it would load the blue progress bar and would be at the end and just sit there, I let it sit there all night and nothing happend. I ran a hardware test and came up with a memory error in J12, switched to just the stock ram, with the same results, then ran it again with the memory in different positions and came up with J14 as the error. Would clean install but have many pictures in iphoto to yet to be backed up.
Thanks
