Best Buy should warranty any work that they do. Take it back to them and request that they troubleshoot it or re-do the transfer.

G5 stuck on white screen


Have you got the Snow Leopard boot disc that came with your machine?

Pop it in the iMac, restart the computer with the "C" key held down. That will boot the imac to the DISC. Once there go to the top menu and run a Disk Utility Repair on the hard drive.

Let me know what happens, I can help with this ;)

Apple 20 in Imac G5 turn on for about 40 second and shut it down itself .. please help


Sounds like you need to reset your SMU and NVRAM:

To reset your SMU:
  1. Turn off the computer by choosing Shut Down from the Apple menu, or by holding the power button until the computer turns off.
  2. Unplug all cables from the computer, including the power cord.
  3. Wait 10 seconds.
  4. Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
  5. Let go of the power button.
  6. Press the power button once more to start up your iMac.

To reset your NVRAM:

  1. Shut down the computer.
  2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
  3. Turn on the computer.
  4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
  5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
  6. Release the keys.
If those don't resolve the issue, your computer will probably need service. Good luck!

Imac G5 will not boot up.


When you boot up g5 hold down the command button (apple logo) and the letter s at the same time to but the g5 in single user mode. When it boot in single user mode type fsck -f so it can check disk on the hard drive and repair Mac OS X. After it done doing check disk type exit and see if it will boot up regularly.

Imac G5 keeps freezing on turn on


Get out your Mac OS disc and restart your computer and get that disc into the drive. You may need to restart with the disc in, but that's ok.
Just restart again with the "C" Key pressed and the computer will launch with the OS disc, and then you can access the file menu when it finishes launching.
Choose "Disk Utitlity" from the file menu and you can repair the system files on your hard disk.
then restart without the disc in the drive.

Cannot open 3rd generation iMac G5


I also had the same issues. The cord when i would jiggle it out slightly then push back in would restart the computer. I truly wouldn't mess with it too much. What it was for me was simply giving it a dedicated outlet for some odd reason. However, to remove the back. Lay computer screen down on a towel. Lossen the screws, they do not come out, mine didn't. Remove the panel and that is that. The entire back did not come off fo me, jus the panel to add more memory.

IMAC G5 Boot problems


This sounds like the HDD hard died. Sometimes you can hit "option" at the startup to see if the HDD is corrupt. If you see a file with a questionmark in it, then you need to reinstall the OS, BUT before doing this, restart it and hold "apple T" it make the HDD and the computer a giant external hardrive. Just get a firewire cable and backup the hard drive onto another system before reinstalling.

If you see a disk icon come up, there is definate directory problems as it still recognises that it has a hard drive. Disc warrior might fix it.
