Will not power up!
My iMac will not power up, I have to hit the power button many times before it powers up. Eventually it does and works OK. I try to leave it run all the time but sometimes it shuts down, I don't know why. I do not shut it down but maybe someone else does, or maybe it shuts down on its own.
I'm wondering if it could be the power supply or possibly power switch?
