My Old Power Pc G5 doesn't shut down.

Hello guys! So I have a Power PC Mac G5, it means really old, I do have this machine about 10, 11 years, at least and never it gives me any problem, just some times the fan starts to run while I'm use it, but just once in a while. Okay, so now it doesn't shut down and take a several times for it, but it won't, for sure. I'm ****** off because of it and I get starting so nervous about this, so I have a lot of stuffs in there, movies, songs, pics, documents and whatever on it, but I have to buy the external hd, okay so forget about the external hd. I'm here to ask to solve this problem. Please, do you guys have any idea to solve it, shut down the machine, get it back to normal, if so, please, help me out. Thanks a Lot!

PowerMac, Mac OS X (10.5), Leopard

Press and hold down the Power button until the machine shuts down. After you restart you will need to find out what is blocking shutdown such as a program hanging or file corruption, etc. Also consider doing this:


Repair the Hard Drive and Permissions


Boot from your Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.


If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

Hello buddy! Okay, I do not have the discs to reinstall the same version of it, but like I said, my system is Mac OS X 10.5 Leopard e doesn't shut down for sure, but still working. So, if I do a backup with Time Machine using External HD? What do you think about it?


I'm waiting for your reply,


Thank you very much!
