Acer :: 5672 Died

i had my acer far a lil after a year and it died on me. i know it over heats like a fresh baked cinnamon roll in your hands. i added heat sinks to the chips helped a lil. anyway. laptop was running fine. played cod2,tf2 etc. i left it on playing music and all of a sudden, died. it just turned off. tried the power button and bought a new charger. still no go. i plug the ac adapter in without battery, nothing. when i plug it in i c the ac adapter blink. laptop shows no sign of life, none of the leds light up. i tore down the laptop for further inspection. cpu looks fine, memory looks fine, hard drive still works on my desktop.
