SOURCE: iPhone Freeze - Panic: We are hanging here

Hello!

try this simple steps to recover your iphone:

-- Turn off your iPhone by holding the "Sleep/Wake" button for about five seconds and then sliding the red slider.
-- If your iPhone is already off, there's no need to turn it on and then off again.
-- Once it's turned off, press and hold the "Home" button and plug the iPhone into your Mac or PC.
-- Keep holding the "Home" button until you see a yellow triangle and text which says "Please Connect to iTunes".
-- New iPhones will show a dock cable next to the iTunes icon.
-- You can now release the button.

-- Open iTunes (if it's not already open) and you will be told that "iTunes has detected an iPhone in recovery mode".
-- Click "OK" and you will be taken to the iPhone pane. --
-- Click restore and you're done.

Depending on the extent of your iPhone's ills, it may take some time to do a full restore. Once you're done, however, you should again have a perfectly working iPhone.

To fix this problem, download and install Mac OS X 10.4.8 from - www.apple.com/support/downloads.
This should solve your problem.

Let me know how it went.

SOURCE: MAC PRO dual2.3- freezes, gray screen crash,

All computers will shut them selves off or crash when fans are failing, or have failed. Cooling fans are plugged into the motherboard, and firmware on the MB keeps track of the system fans, along with everything else. If a system fan is failing, or has failed, the signal is sent to shut down. Some PC's will shut down cleanly, others give error messages, and some just freeze up. Of course, Bad RAM, video cards, and hard drives with bad sectors, can also cause problems like you have discribed.
I would write down any error messages, and beep codes, and then look them up online for a place to start.

This message indicates that the CD you are attempting to boot from is a release of the Mac OS which is incompatible with this model of Macintosh. I would recommend a retail disk of Tiger or Panther for this vintage Mac.
