Memory reasons. When the contact between the memory and the motherboard socket is loose, it may also cause the computer to shut down automatically, it is recommended to check whether the memory is plugged into the motherboard.

Power issues. The lack of power supply is also an important factor in causing the computer to automatically shut down, but from this configuration, the possibility of this problem is very small.
