Sorry but this will be a long one... It started a few months back when i was using my desktop, it suddenly closed down all the apps and shut itself down, then it would restart, and after a few seconds it would shut down and this repeats forever till i force shut it down . I took it out for repair and they said the motherboard was "fried", so i bought the same one and replaced it. It worked fine for a month, then it came back. I opened up coretemp before its next restart, and voila, the temp was rising rapidly until it hit 70 degrees and shut down. Fyi its not a BSOD or an abrupt power off, it just shuts down normally. After a few restarts, it oddly started to work fine? So i used it as normal and shut down at night, just to find out it went on a boot loop from night till dawn without stopping and i had to pull the plug in the morning. Before it became unusable, i monitored the temp of my i3 4150 and it was idling around 40 degrees and would rise to 60 occasionally. It was the same exact problem as before i switched the motherboard. I bought a 8gb ddr3 hyperx fury ram and installed it along with my motherboard less than 2 months back and it was working fine until recently.Before, it shut down due to overheating, but now it just shuts down like 3 secs after i boot it, so im thinking its not overheating anymore but some other problem. Maybe the cables? or the PSU? or even the core? Cause this rig has been built since 2010. Up till now, the PSU has been changed once, a new GPU was installed, more ram was added and like i said I also replaced my motherboard. The core i3 4150 has been left untouched till now.

Sorry im not good at this stuff and am pretty lost. Any help would be appreciated. ༼ つ ಥ_ಥ ༽つ
 
Solution
Have to know what cooling you have present on the system, and if you can confirm it's running (CPU fan especially).

I would question the fan, the heatsink, it's contact to the die and the CPU thermal paste. Is the fan moving? Is it moving quickly enough to move air? Is it venting air upwards? Is the warm air being moved out of the case? If all answers are Yes, and there's still overheating, I would question the CPU heatsink or some other part of the system getting too hot, such as the mobo chipset.

Solution

1. The CPU thermal paste was replaced last time I had the motherboard replaced.
2. Im using the cpu stock fan and yes its venting warm air our of the case.
3. the mobo was fairly new (2 months) so It's kinda hard for me picture it being the root of all this.
