I have just realized this is what has been causing my computer to turn itself off randomly. Yesterday I was playing Don't Starve like I do occasionally, and that's when it started. My computer turned off all of the sudden. I have never had any problems like this since I've owned this computer for the past year or year and a half. All the fans are running. This problem just occurred over-night for no apparent reason. I hope someone can tell me I don't have to shell out for a new CPU! If anyone is curious I am using the AMD FX 6300 Six-Core Processor. Help much much much appreciated!!!
EDIT: Also if it helps it's a pre-built PC
