How can i stop my beeping on my fisher and paykel fridge?

Stupid thing. Have had it over 6 years now. anyway the top half of the fridge is quite warm, whether is in the bottle rack/holder thing and the vege bit, it is freezing up everything. Also freezer is freezing up too much. Also the beeping. It will not stop. Its even beeping now. Also noticed the green lights where you change the temp from warm or colder etc is flashing with the beep.

Can someone help, not actually say 'oh yeah mine does the same thing'. Also any advice on anything that didn't work

haha, ranting on here. Thanks guys
