PC restart MSI Radeon HD 7850

[rawrdino]

So recently i bought a new pc by parts (which was assembled in a shop). The first few hours everything was fine, i ran Crysis 3 on high textures and rest on very high. Then i approached a part of the game where the PC just restarted out of nowhere. After few hours i returned to PC and launched Crysis 3 again. In just few seconds of gameplay PC restarted. Then i ran Kombustor and in a minute GPU temperature rises to 66C degrees, the GPU starts ticking and PC restarts. Any help would be appreciated.

Specs:
MSI Radeon HD 7850
4gb RAM DDR3
600W PSU
AMD A8-5600K APU Radeon HD graphics

That is pretty weird. 66c is not high. High is 80+.

Did you tried any other game? Take it to the guy who made it and tell him you are experiencing the above mentioned error.

I don't have any other games at the moment and can't take it to the guy today.

I completely uninstalled the drivers and installed them again. Increased the fan speed and was able to play crysis 3 for few minutes until once again some kind of ticking sound appeared and the PC restarted.
