and sometimes i put it in sleep mode and come home on my lunch break and the fan is running at full speed and the computer has frozen up...what is going on here? is it a virus or has my computer been hijacked? it cant be good for the computer...anyone ever had this problem..?
Your problem has been reported many times, but causes are as varied as individuals.
Can we assume that a hard shutdown allows a normal restart?
Can I assume that you have used Disk Utility from your OS X install disc to repair the hard drive directory? The freezes and hard shutdowns require that the drive be repaired (not permissions) or soon the machine won't boot at all.
If the root issue is software related, in Console (the application) under Logs, there should be loggings around the time of sleep and logs that tell you what process went wild and froze the machine.
Network activity is also a common casue.

If hardware related, such as an external drive, other USB device (Wacom tablet) or USB PCI card, ejecting, disconnecting, removing, or in the case of the Wacom, updating drivers, are all potential remedies. -
Updated to 10.4.6 and computer has frozen during installation. Help
was prompted to install update of 10.4.6 but during the installation the computer has frozen. The little bar that shows progress of installation is almost at the end but computer is frozen. the mouse cursor moves but nothing else responds. no previous problems at all until this moment.
i have spoken to the apple shop where we bought the computer, they suggested restarting to see if it has hopefully installed properly. Any suggestion on whether this is ok to do or what else to try? any suggestions gratefully appreciated.

My ipod touch has frozen! Will only show a USB cord pointing to "itunes" CD symbol. When I try to plug it in, my computer says that it cannot recognize my device due to malfunction. Tried to reset the ipod twice, but didnt change anything.
- Try another cable as yu siad
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

My ipod touch has frozen with a white screen. The on/ff and sleep buttons will not work whether pressed for a moment or held for more than 10 seconds as per help pages. When connected to computer it is not recognised and no indication in "devices".It has been working perfectly from Christmas until now. Was watching a TV prog via BBC iplayer when the image and sound froze for about 5 seconds then just white screen. Help
First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes." -

My IPhone 4 has frozen and it is brand new

Have you synced it with the computer yet?

Since migrating from Windows 7 to Windows 8 and upgrading to iTunes 11, the latter has frozen while syncing my devices, usually while at the “determining apps to sync” stage of the process. If I am attempting to download app updates before attempting to sync, the problem normally occurs at the first “installing app x” stage. In addition, the whole iTunes experience is extremely sluggish and will even freeze while searching for a track. Everything worked fine on Windows 7. So far, I have repaired the program several times and have checked for compatibility issues, but there is no Windows 8 option in the combo box, obtained after right-clicking the icon and selecting Properties/Compatibility. As a result, I am unable to sync my devices. If I uninstall iTunes before re-installing, will this affect my iTunes libraries? Does anyone have any suggestions?
After going by elimination to isolate if the problem was from (1) iTunes app, (2) my computer or (3) my old iPhone 4G, I figured out what my problem was.
1) First I deleted & reinstalled iTunes on my Windows PC without succes, my playlist did not changed on my iPhone.
2) I tested a successful #sync from the iMac at work.
So my conclusion is: The hard drive on my Windows PC is full and that is affecting iTunes SYNC functionalities.
So I'll do a back-up then run a "Clean Install" of my Windows OS, hoping that it will fix my SYNC problems.
