Can you boot into recovery mode?
If not: personally, I would try another hdd before ruling out that it has overheated.
Don't use the hairdryer..lol
If anything, go spend $30 on a heatgun and purchase some new thermal paste (arctic silver 5, cost about $13) remove the mobo and blast the CPU/GPU and replace paste..
but its really bad to let the console get to the point where it actually shuts off. If it does, you can't expect to fix it 100% without above average repair and even then it is vulnerable to happening again..all you can do is try and hope for the best or just get a new console.
You should try to make a routine of replacing the thermal paste in the console (every few months, every year or so?) to prevent this type of thing from happening.
Good luck!
