I bought a new Mirrior Door Dual 1.25 G4 back in July 03'; in September it freakishly booted up with the flashing "?" folder icon... Apple sent me a HDD and it was replaced as well it was taken in to a Apple repair center they replaced the logic board. Now about 2 weeks ago the same exact thing happened... the machine was running perfectly normal as far as I can can tell, it was shutdown and the next day when I booted up there was the flashing "?" again... so Apple had me bring it in again. The techs at the service center are not "positive & sure" what did it... so they are just replacing the HDD again... now if this was the problem I would be happy with just a HDD switch, but the aggravation for rebuilding and being that the Logic Board & HDD have already been replaced what could be doing this? I had a very lengthy talk with Apple earlier and expressed my concern for my machine and I can't get an Apple Care because I'm in Florida... my warranty expires in July so it's roughly close... I would seriously be broken hearted if I take back this machine and it decides to freak out again after the warranty expires. Shouldn't Apple just replace the computer in whole for sake of assuring no problems with it? What should I do? Thanks for anyone who took the time to read and anyone that helps.
