iMac fan running and computer will not reboot or start
iMac Intel 24" EMC 2134
Don' t know if a power surge caused this. Computer was contacted to power surge protector. iMac fan is running fast and computer will not turn on and will not reboot. Screen is black. I have unplugged it and waited 24 hours and symptoms persist. It ran out on AppleCare in April .
My question is could this be a simple fix (ie hard drive) -- not costing much or the CPU ( a much harder and costlier fix). what is the best way to figure this out.
Is this a good question?
