Okay, so my 4-year-old G3 iMac suddenly decided it didn't want to boot up anymore. This is annoying, but I was planning on replacing it soon anyway. So I took it into the local Apple store to find out what was wrong and they thought it was a problem with the power supply: the computer begins to turn on, but halfway through the "bong" sound, it immediately shuts off. SO... I was wondering if it were possible for me to access the iMac's hard drive and export the data onto an external hard drive? The Apple guys said they could do this for $80, but I'd prefer to save the money and do it myself if it isn't too difficult. Any suggestions people can give are very greatly appreciated. Thanks!
