Most of the time when a Mac overheats it does an auto-shutdown for self protection. I would open it, see if the fan is running, remove the fan and clean the vent, then test again. To help us with diagnostics please give us the last four figures of your serial number. To test for a software conflict or possible virus, hold down the Shift key on start up. Let us know if any of your results change. Also how much available free hard drive space do you have and what OS are you running?

moh fuaad - How about installing this app to see what is causing your system to run hot TG Pro I find it has helped be diagnose overheating issues.
Also what is your drive a HDD or SSD and who's and model if you upgraded.
