I have an older iMac. It's about ten years old and we use it for a guest/kids computer. Just surfing the web, watching netflix. Anyway, I had a feeling something might go wrong with it soon, the hard drive (I think, could be something else) makes a weird noise every now and then. Today, I had to shut it off to move a power strip and it won't turn back on. I tried the only "trick" I could find online and that was to make sure everything was unplugged from it, unplug it for a bit and try again. Nothing. So....I made an appointment with at the apple store in two day but was wondering if in the meantime anyone had any advice as in: forget it, its way out of coverage and any repair won't be worth the money.... or did you try to restart it this way.....or how the hell should we know what's wrong with it, just go to the store.... Thank you in advance.
