    Hi,

    I have seen several threads on the Internet but never an answer to the noise problem Imacs seem to have when in sleep mode. We have an Imac, 27' 10.6.5 2TB bought this summer, in the bedroom which we use as a TV. When we go to sleep we put the Imac to sleep as well with the remote and the ZZZ on the screen. During the night however the Imac fan or harddisk starts to spin as if the whole thing is going to startup but then it winds down again and it does this every hour or so. It is so loud that it wakes us up. Some nights it does it some nights it doesn't. Before we actually had the screen come on too but now it doesn't do that anymore. Anyone any ideas on this Gremlin ?

    Cheers,

    System Preferences > Energy Saver > Disable "Wake up from network connection". Also, try SMC and PRAM resets and repair permissions with DIsk Utility
