help!

i drove home from work (5 minuite drive) and a flashing light came up. the car wasnt running very well. the light was the outline of an engine with check inside the outline. it flashed for about 30 seconds then stayed on. the tempreture gage rose within 1 minuite then i pushed car home cuz i didnt want to do any further damage.

what thye hells wrong? i checked the oil and water, power steering liquid, and they are fine.
