Can i have some help?
Old i3-2310M laptop, turns off from overheating, however there are no problems with thermal compound or heatsink/fan and this only happens in specific situations, it's not caused by CPU cores usage, it can handle stress tests with only thermal throttling after 85° C, the shutdown only occurs when the integrated graphics is under certain load or in certain conditions, i identified this using HW monitor, i opened a game where this happened, when i clicked on the game window the integrated graphics temperature jumped from 55° C to 81° C in 2 seconds and the GT power consumption also got up, while core temps and consumption stayed the same, after that repeated the same and the temps quickly risen to 90° and turned down. This do not happen with every game or, in fact i am able to hit max video memory usage on top clock speeds without overheating and shutting down.
Soon i'm going to do a clean windows install on another HD and hope that this is a driver problem, but it seems unlikely. The LCD screen of this laptop also have some stuck vertical pixel lines, but i don't how that is related. What the hell is this? Something is shorted or some transistor is blown? I never have seen something like this on "modern" CPUs. I searched about it and some similar cases on desktops had problems with either motherboards, power supplies or some crazy shit.
