my PC shuts down or rather turn itself automatically while the PC is idle. After the PC shuts on it's own it won't start no matter how many times i push the start button and would turn on itself after 2-3 hours. My PC temps are OK. Only one way i can start the PC after it turns off on its own.http://. Refer to the page 32. If i do these steps mentioned in page 32 the PC turns on otherwise it would turn on it's own after 2-3 hours. I have checked my psu and it's working fine as well as replaced my cmos battery. plz help.

psu: Circle CT 600 watts
Graphic Card: Evga gtx 760
Storage drive: Western digital 1tb for storage, 256gb Samsung evo 850 for OS
