@momof2boys , Maureen, I do not think you have to worry about frying the mother board because of factory resets. There are different opinions on whether Two many factory resets will actually do any damage. Check the links below for more info.. After you factory reset your iPad, watch what you are loading back on to see what App, game,data,etc., makes your iPad not respond correctly and then delete the App, program,etc., and try. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.
