Crashes around 1 hour of playing...

Hey everyone, i was looking for some help with this, i got a new pc with W10 (i3 7100, RX460, ddr4 8gb) and i cant play more than 1 hour, around that time i start to see things like in the image:

And then just crashes, idk what to do, the temperature is normal, i check the drivers of the graphic card and its fine, i close apps of W10 that could be a problem, but still crashes.

I hope you can help me :/

THANKS!
