Hey guys, I have a 3-or-4-year-old Mac Mini Core 2 that has just in the past day or so stopped wanting to turn on. The symptoms started with OS freezing up, so I had to shut it off by holding down the power button. When trying to boot it back up, the apple icon showed along with the loading indicator and it never started up. I turned it off and let it sit for a day or so, but now the same loading screen shows for about 30 seconds to a minute until it shuts down again. I tried switching outlets, opening it up and cleaning it of dust and still no dice. Any ideas? Thanks so much for any help!
