PROBLEM TO BE SOLVED: To control a machine not to excessively switch systems when a fault of the machine is caused by a high load of the machine and to enhance work ratio of the system as a result of control. SOLUTION: This computer system is constituted of plural machines and switches systems of a machine where the fault is generated by a machine allocated to the machine where the fault is generated when the fault of the machine is generated, each machine in charge of switching of the systems of the machine where the fault is generated, for example, a machine 1 is provided with a load information storage means 102 to acquire and store load information including load values of each machine of the computer system via a load information transfer means 103 and a temporary high load predicting means 101 to predict a temporary high load state based on the stored load information of the charged machine when generation of the fault in the charged machine is detected by a monitoring and system switching means 104 and when a temporary high load is predicted, execution of switching of the systems is postponed for a fixed time by the monitoring and system switching means 104.
