Stuck closed thermostat, inoperative cooling fans, internal leak from blown head gasket or crack, low coolant level, no water pump/broke belt/seized, clogged radiator. A pressure test, and a block test for presence of combustion gases in cooling system would be a start. More specific information on under what conditions it overheats might provide some insight.
