At first I was scared and thought that my laptop was dying, but then on the Internet I found a person whose computer was twice as good as mine, and his computer was also forced to reboot.

I have very beefy and well maintained machines (PC and Laptop) and never experienced this with voices of the void, even on the highest settings. The only time I crashed the game was by changing settings too fast before everything could be loaded and spamming buttons so the engine told me to fuck off xD.

An Intel i3  and a nvidia mx110 could reach their limits to run most games but Voices of the Void should somehow run at the lowest settings, maybe. I am not sure because these two components are unfortunately pretty old/slow, plus they have been slow, when they were new back then. 

But generally: If a computer suddenly turns off/restarts without any warning this means the CPU, the GPU or the power management of the Mainboard/PowerSupply shut down to protect any of these parts from getting damaged. This doesn't mean anything is broken or dying, it just means something runs too hot or too long over it's defined limits.

Update your drivers to the latest (Chipset, GPU ) and let AIDA64 or HWinfo (only sensors) monitor your temperatures while you run the game. If your CPU and GPU stay below 85°C they should be okay. Otherwise clean your fans and the passive coolers (fins). Get someone that can help you with opening your laptop safely to not damage anything.

From the age of the laptop I would also recommend replacing thermal paste and thermal pads.

If the temps are fine you need to do some advanced analytics because it could be a dying component.
