[QUOTE="Rod, post: 1584756, member: 204485"] Ok, as stated your external drive is probably alright so disconnect it and if your mac has cooled down try starting up with Command+R. This will access the restore partition and allow you to run Disk Utility. From here you can reinstall your OS while keeping all of your old files. If your operating system was corrupted for some reason this is the best way of reinstalling it HOWEVER if you have an overheating problem it may not be able to complete the reinstall and that will leave you in an unfortunate situation. If it can complete a restore you can then use Console to check if the shutdown was caused by overheating at the moment we are a bit in the dark as to the cause for the crash. Do you have a full backup? Either Time Machine or a bootable clone? [/QUOTE]
