Disclosed are a system restart circuit and system restart method thereof. The system restart circuit includes a capacitive element, a first end of which is coupled to a first voltage level; a restart switch for coupling a second end of the capacitive element to the first voltage level selectively; a first circuit for establishing a current path between a second voltage level and the capacitive element during a restart time, and setting a voltage level of an enabling signal of a system power supplying circuit according to the voltage level of the second end of the capacitive element; and a second circuit for controlling the first circuit to continually establish the current path during the restart time. The present invention can spontaneously restart the system when a restart signal is detected, so that the hardware restart can be accomplished with low cost.
