Boot issues .... Goes to sleep .. Won't wake up .. I am planning to buy my first iMac and it's made me wonder if it will last atleast 5 years .... Can't afford to replace my iMac every 2 years like some folks down here ... Please help me out here .... Are these failing iMacs uber old or iMacs do toast too long.
