The computer will automatically stop running for a minute or so, without any reaction, after restarting.
There are generally three kinds of reasons for this failure, one is the problem of the chassis switch, the other is the power supply has been damaged, the third is the problem of the motherboard.

Remove the motherboard and install it on another computer for normal use. A careful view of the chassis, found that the design of the chassis is unreasonable, the motherboard is fixed, the back will contact with the metal floor.

An insulator can be placed between the motherboard and the chassis, and the failure can be ruled out.
