I have i laptop that for 2 years operated just fine in all aspects. Suddenly while i was playing bf3 at the summer it shut down. From that day even on very old and not demanding games like dead space 1 or lol. The temperature goes really high. I have on a flat surface with a 2 fan cooling base and even on a room with air condition and i had the input/output cleaned but nothing changed.

The temps when i was playing games before the sudden overheating where:
gpu max 65c
cpu max 75c

now every time i open a game the temps on the gpu goes around 70c and at the cpu even 85 or more,on no demanding games like that my system can easily handle, and after 5-10 minutes the laptop shuts down. I did a research but i didn't found anything trustworthy or specific only staff like ''you thermal paste was evaporate open and place some more'' or download 5 different antimalware programs and run them all to find the virus''.

system cpu intel i3 2350 2,3 GHZ
gpu nvidia gt520m
ram 4GB

I know low end gpu but games like BFBC2 dead space 3 hitman crysis or (just like i found) bf3 can be playable.
