I have a good system for video editing, not tough notch but good. Whenever I render video from Premier pro my computer freezes and had to start os manually, even reset button doesn't work. My rig is X79 MSI GD45, i7 3820k, EVGA gtx 780 classified, Corsair 4X4 16GB RAM and OS is Windows 7Ultimate 64bit. This rig is over 3 years old. Can any one suggest me? Is my cpu failing?
