Hi, my eMac is somehow shutting down after going to sleep. I've checked the system preferences under energy saver and there are no schedules set for the machine to turn on or off. It does not happen immediately. It usually happens after a day or so. When I return to wake up the machine, it doesn't respond. I then have to start it from the start button. I don't get any error messages regarding the machine shutting down in the wrong way...just boots up normally. I've had it for 5 years and this is the first time this is happening. Has anyone experienced this before? Can my machine be "infected" and controlled externally? Thanks in advance for any help/suggestions.
