Verlauf von "Red and green light..." bearbeiten

my raspberry pi 2 first worked for a couple of days,  but one day when i plug in the power the green light just stayed on, it was overheating rapidly, also making a squeaky noise and was not booting. After a couple of days i left it and this time when i tried booting both the red and green light would come on and would not boot to my os.

can some one please tell me what to do?????
