Hello, first post here as I am at a loss as to what is happening. All was fine, I was playing heroes of the storm on a quite old machine with a EVGA GTX 970SC and things were running fine. I have since upgraded most parts but with the same graphics card and same HDD now I can play heroes of the storm for roughly three seconds before the computer restarts itself, idle seems to be fine.. world of Warcraft seems to be fine, at a bit of a loss whats happening... I believe the fans on the evga start to spin around 60c and this is around the time the computer restarts. CPU idle temp is around 26c and GPU idle temp is 35c. I got two fans bringing in air on the front, one exhausting air on the back, and the fans on the radiator blow out through the radiator out the top. (ive tried to do an airflow diagram up top) anyone got any ideas?
