Ok after procrastinating for awhile I finally decided to replace my hard drive as a previous reinstall (as well as other things) did not help and the disc utility said the hard drive was failing. Its an older 2008 Imac so no big deal. It had a good run. So I picked up a new hard drive and followed all the steps on fixit to replace it (not a novice to doing this stuff on a pc just new to it on a mac). After putting it all back together I was rather happy when the unit powered back on to a flashing folder with a ? I slapped in my snow lepoard disc tried to reinstall however it loads to the apple logo, does the little circle load thing and then goes to a blue screen and nothing. Does the same with the origional install discs as well. Am I missing something or did I get a dud harddrive? Sorry if I am missing a post that covers this I have been fighting with this for a couple hours and my search fu is weak.
