(Solved) Asus turns off while using a discrete card (geforce 540m), how to fix it?

Question

ASUS

In general, the problem is as follows: there is an Asus laptop, it turns off literally after five minutes, and at another moment and after half an hour in games. Overheating is definitely excluded - I cleaned the cooling system, changed the thermal paste - it did not give any results.
Below is the data on the system at the time of shutdown
In the end it turned out that the discrete video card was to blame, on the integrated intel hd 3000 - everything is in order, is it possible to revive the geforce or just a replacement?
The solution was to replace the charger, which was not taken into account at all initially.

Answer 1

Battery?

Answer 2

81 degrees on the processor suggests that overheating is not excluded at all. Budget laptops are often equipped with a frankly weak cooling system that requires improvements, rather than simple maintenance.
