It is not a simple as that there are many earth cable connections on a car - but you could start with the battery. Are the battery terminals all clean and secure - is the earth cable to the engine clean and sound and it is also worth having the output voltage of the alternator checked - if it is faulty it can cause electronics to go crazy. Also it may help if you could explain exactly what is happpening.
