I would check CPU temperature, maybe re-apply thermal paste. Check windows event viewer, that should give you a pretty good idea of the error, look for errors marked "critical". If none of that works maybe try a windows re-install

Crashes that result in an unintended shutdown are generally power related. At some point in the game, your components require more power than your PSU can deliver, and it will therefore crash the system.

According to this:
http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html
Your PSU is in tier 5, the "avoid at all costs" tier.

I would recommend getting a PSU from at least tier 3 in the 500 to 600 watt range. See if that will cure your crashes.

Sea sonic s12 II bronze 520w.
Be suitable reliable and worth the money?

That is a solid unit. It should have no problem powering your system.

I checked windows event viewer and the only critical thing was kernel-power. Also my Core temp is ranging from 40-70°C
