My computer turns off by itself automatically

[Martin Kvia]

when I open minecraft open settings and seats fps settings at max fps so it goes 30 sec to 1 min and then my computer automatically restart. but if i set power saver instead of max fps then it goes 1 min to 20 min before my computer automatically restart. same with borderlands 2 fps settings are on fps unlimited then my computer automatically restart.

the computer is brand new

Sorry if wrong category

The word 'power saver' did lead me to a guess that you're most probably using a laptop. Check out the temps in the 1 min. It's a heat issue imo.
