What is a free, yet safe CPU Temp program for Win 8.1. My rig specs are below. I ask because when I play certain games, they will perform excellent for a few hours, but then all of a sudden, the screen goes grey (I get the "d-sub" icon in the top left of screen) then my PC reboots. No error messages at all. I log back into game and am fine. Was wondering if my CPU gets hot at certain points in the game and restarts.
