I have a gateway m-series. AMD Turion 64 X2 Mobile Tech. I am having overheating problem after a while from being powered on it start getting hot but only when im using it wheather its light or heavy CPU usage. Then all of a sudden just shuts down. I have applied new thermal paste from Artic Silver 5, artic cooling mx 4-5, and COOLER MASTER IceFusion. None of them really helped much. Also one thing the cooling fan has a slow fast running rythem. If I leave the bottom cover and its idle the fan completely shuts down.
