Hi, My imacG5 2.0ghz hrd drive can't be found. I just got my new MBP yesterday (thank god!) and after performing a erase and install yesterday, I'm getting the ol' blinking folder w/ ? . I've got applecare. I have installed ram myself. Should I take out and put back the original 512mb before taking it in? Pretty sure I still have it. Can I just take it to apple store? I've also been experiencing random bright green pixels flashing around on my monitor. Specifically, in darker areas of desktop wallpaper. The imac has (or had) a clean install straight from the original disc. Nothing else was done. I go to it this morning and it's stuck in sleep mode and making noise. Once I rebooted manually, I got the flashing folder icon. Then I restarted w/ install disc and it can't find a destination drive to perform the install. D'OH!!!! THanks, paisios BTW....new MBP is SUHWEEEEEET!
