Hi! So I´m new here. Currently living in Chile and having Mac trouble, and unfortunately there is very limited knowledge of Macs here (and of course, no Apple stores). I have a MacBook Pro from 2012. This morning I tried turning my laptop on and it booted up to where the grey bar was about 3/4 of the way complete and then it went black. When I shut the laptop, the light on the front was still on. I had it plugged into my charger so I don´t think it´s a battery issue. Yesterday it seemed to overheat, the fans were going for quite a while so I left it alone but kept it turned on. I shut it off and the end of the day as I always do. Tried booting up about four times and each time it went black. I also tried holding down Command R and using Disk Repair, that didn´t work. I have limited knowledge of Macs but unfortunately being abroad I´m pretty much on my own in fixing this thing. Any advice would be greatly appreciated! I also recently replaced the hard drive.
