My Toshiba Satelite keeps shutting down. It has an Nvida graphics chipset. I was running a monitoring application on my Nexus and noticed the unit powered off when each of the core temps were at 208.4f, - ambient temp was 98.6f and GPU core at 213.8f. Is this likely the reason the unit keeps shutting off? I have it elevated on a perforated aluminum stand but maybe this isn't enough. I have to get this sorted ASAP. Thoughts on a relatively inexpensive solution?
