Hi,

 

Can you turn on the machine and as soon as you let go of the power button can you press and hold the Command+Option+P+R keys on the keyboard.

 

You must press this key combination before the gray screen appears.

 

Can you then hold the keys down until the computer restarts and you hear the startup three times and then release the keys and let me know if the machine will then boot cleanly.

 

If not can you try booting the machine again and this time can you hold down the Command (Apple) key along with the S key until the screen turns black and text begins to appear on the screen which is Single user Mode

 

In single user mode there is no graphical user interface so when the system finishes starting up a few seconds later it will wait for a typed command.

 

At that point can you try typing fsck -y and press enter.

 

The system will proceed to run a comprehensive file directory check, repairing problems it encounters. If it does find errors the it is advisable to run the program again and again until no errors are detected. Once it is finished can you then type Reboot and hit enter to restart the computer and let me know what happens.

 

Thanks

 

Eric

I tried the first directive but I only heard the start-up 2 times. I then tried the second but never got the black screen. Both just took me back to the grey screen w/ the apple and the fan noise would start up after a moment

Ok,

 

Can you power off your machine then wait 5 seconds then power it up and immediately press and hold down the option key on the keyboard and keep it held till you hopefully come to the Apple boot menu.

 

You should see a picture of yoru hard drive and if you do can you click it then click the right hand arrow and see if the machine will startup.

 

If not let me know if you have your OSX disk for your Mac.

 

Thanks

Ok, I just found my disks so I guess you know what that means............
What is my next step?

Ok,

 

I would like to try verifying and repairing the disk so we can see if there is an issue with the OSX software.

 

Can you put the OSX disk in your machine then shut it down.

 

Once it is off can you then power it back up and then press and hold down the C key on your keyboard till you see the apple load wheel under the apple icon and then let go.

 

Your Mac should open to the installer menu and when it does can you then choose English from the menu and click the right arrow.

 

Next can you click the Utilities menu on the top toolbar and choose Disk Utility to open it

 

When it opens can you then choose the First Aid tab and select your OSX disk on the left

 

You should then have the option to verify disk and repair disk, If you could run a verify permissions first then run a verify disk then run a permission repair and a disk repair, If the disk repair gives you an error can you run it a second time.

 

Once that is done can you then restart your Mac and let me know if it will now boot cleanly and run correctly.


Thanks

sorry this is so much trouble....when I get to the first aid part the only option is for me to verify the disk permission and when I do that it indicates ERROR: no valid package.............???

Ok,


Have you deleted anything recently as that error usually only appears when you delete a file or all the files from the /library/receipts folder.

 

At this point we can try a safe boot and see if it will repair, however if that will not work our only options would be another Mac and a firewire cable or to perform an Archive and install which is where you reload the machine and choose the archive and install option so that your files are archived so you dont loose your data.

 

To try the safeboot can you power off the mahcine and then power it up and immediately press and hold down the Shift key and keep it held till you see the apple log with the load icon beneath it then let go and wait.

 

Depending on how bad the damage is a safe boot can take 30-45 minutes before it brings you to the login screen.

 

If you wish to try that and let me know what happens or if you prefer I can give you the instructions to perform the archive and install.


Let me know what you prefer

 

Thanks

I will give it one more try tonight...first I have to plug in my laptop or I am going to lose you.
I had not deleted anything that I was aware of. I was on a website for controling your new puppy from biting (LOL) when it froze up. I do have a back up in place but I am not sure how that works with a new MAC...I sure hope that is not the case tho...

Ok,

 

This may sound weird, however I had another customer a couple of nights ago that picked up a nasty Mac virus, Although they are very rare and it is usually months apart if I see them it is strange that two people have had the same type of issue in a week.

 

If you could try the safeboot, You may actually wish to start the safeboot running and then let it run overnight just in case then let me know back in this thread tomorrow what happened.

 

As to your backup is it a time machine backup?

 

If so it is really easy to retore them to a new machine or a newly loaded machine.

 

Thanks

What Customers are Saying:

Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill
