[QUOTE="chscag, post: 1610542, member: 46727"] It would help if you provided more details about your iMac. Year and model? And version of OS X? Also your location. Brown outs or power line spikes are detrimental to any electronic device especially a computer. It does sound like it may be a power supply problem and as advised it's best to let an Apple tech look at it. Also if your area experiences brown outs, it's best to use a line leveling uninterruptible power supply (UPS). [/QUOTE]
