UNABLE TO REFORMAT DISK


Do you have access to another computer to try reformatting the disk on? Or has your computer been 'acting up' lately? If so, the BSOD is probably just that & it's time to start looking for a new computer. I had this happen to me recently and took my computer in to a reputable repair store in my area that I had used before and they did manage to retrieve MOST of my stored pictures and media. But, I'm sorry to tell you, the computer never worked again. Good Luck!!!

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 ;)

My 24" Aluminium iMac (early 2008 model) with 2.88Ghz 320g hard drive and 4g rams would freeze out of nowhere...I have ran various program tools to scan (tinkertool, DiskWarrior etc) soft and hard ware but...


Thank you for contacting Fixya Support, I am glad to assist.

In cases where you are experiencing issues with your iMac 24" and you have already tried hard drive and software repairs (including Tinkertool and Disk Warrior), one troubleshooting step I would recommend you try is unseating and re-seating your RAM card one module at a time.

Once you have tried this, then run Disk Warrior, run the Repair Disk Permissions (at least twice).

Once you have run the Disk Repair option, then perform a Disk Rebuild (it will not remove your files from your hard drive but actually rebuilds the Mac OS X directory) and reboot your iMac.

Try this procedure and see if that makes a difference in your iMac's performance.

Let me know if this helps.

When you used the archive and install feature on the installation did you remember to preserve users. If you did not, all you have done is archived the system which will show up as a folder called "Previous System" and none of your files. What I would do is have a look in the users directory the top level of your hard drive and see if there is an archive folder or disk image in there.

Use your Boot OS disks to boot from and remove the file and anything in the start up folder that you dont know what it is. If that doesnt work you may have to reformat.

My imac wont turn on!


It sounds like something is either corrupted on your system or one of the files in your imac may be suspect. What I would suggest is get your system disc boot the imac down holding down the c key on your keyboard. Once it is booted up go to the file menu and find the disk utility. Open up the disk utility and first of all repair your disk permissions and then run disk verify and if an error comes up choose to repair it.

If this does not work. I would suggest installing a clean system. Again with the system disk in your computer restart your machine with the c key held down on your keyboard. Choose to do an install but remember to select preserve users. This will give you a clean instal with your files and preferences intact.

Once your machine has restarted it is well worth setting a second account under system preferences under accounts as if one account becomes corrupt in the future you have a second account to fall back on.

For prevention of any problems in the future I would download Onyx from this website http://www.switchingtomac.com/tutorials/keep-your-mac-running-smoothly-with-onyx/ which also talks you through the method of using it. I use it every month just to keep my mac in tip top condition.

Hope this helps.

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.
