Computer reboots randomly in games.

[roeeguraria]

I have this problem for a long long time now and it had it's ups and downs.
My computer reboots randomly in games and sometimes (rarely) when not in games no matter low/high graphics. i have sent the computer to a lab few times and he ran some checks and ran the computer for 4 days straight on max demands and it didn't crash (so he says) and he said everything is ok with it. However it is still crashing. When. Playing games it goes black screen and reboot.
It's not overheating (60-63C highest record)

I really need your help. I have been trying so many things and nothing fixed it:
-clean win10 installation
-drivers are all up to date and not over lay each other
-deep cleen the computer
-put a new heat paste.
And many more.

Specs:
Win10 64bit
Intel core i7 3770
16 RAM
Nvidia GeForce 1050 To
SuperSonic M12 II Bronze 850W
