I purchased a system one year ago, with the below configurations. It was working fine for few months without any issues. Later my system started shutting down automatically. I checked with my dealer, he advised me to go for warranty. I replaced my CPU and motherboard but issue still remains the same. I have not overclocked the cpu. Below is the config
I see the Idle temperaturtes in the range of 25C - 42C in the coretemp utility.

CPU: fx8350
MOBO: GA-78LMT-USB3
PSU: Zebronics 400 W .

Sometimes(very rare) system will run for 30 minutes before shutdown. Also, after the system shutdown when i try to start it it won't. Need to switch of the supply wait for 5s and then, when i start it system will start and shutdown after windows loading. Please help me out
