Hi, my macbook is just about 2 years old now and i've had no problems up until now. Whenever i try to type using my mac, it randomly inserts strings of appostrphes without me pressing the appostrophe button and will not stop. Also, when i close the screen it starts making a rebooting groan at regular intervals. Has anyone else encountered this kind of problem? It has become so bad i have had to stop using my notebook. Any help would be appreciated.
