Uhh boy that's concerning, I would be looking into why the surges. Was it a storm? Yes it's good practice to replace it after a large power surge. Some have a breaker in them and it has to be reset. Definitly go with a brand that has a guarantee. Generally if no power runs through the strip then it's scrap. The computers PSU itself has some fused protection as well. The circuitry inside detects the surge and cuts off. Don't get power surge protectors and GFCI (ground fault circuit interupters) confused. Surge protectors do pass some high voltages before it kicks and are meant to protect electronics only. They do not protect from a person getting electricuted. A GFCI will give that protection and any circuit connected to it. There is also other special AFCI (arcing fault circuit interupter). Some units now today may be able to detect both GFCI/AFCI. Typically a GFCI is near water like in a kitchen, batheroom, under sink, outside outlet, wash room, hot water heater. However they are still good to have anywhere especially in a childs room and they are tamper proof can't jam stuff in them.
