It boots straight to the system recovery. I got into Disk Utility, and the Macintosh HD partition isn't mounted and is named wrong. Format it and name it, run disk verify and repair, looks good. Attach external hard drive, start to do restore, it turns off immediately. Do the same process but start to download OS X via their restore method, it turns off. Leave it just running booted, it turns off after 30 seconds or so. Any ideas? Im thinking its overheating and turning off?
