Could be a temperature problem. Install this program and start playing a game for about 5-10min then reply with the results:

My pc is clear from dust and it has new drivers on it. So ?? After some games:
GTA V
MGS V
The Sims 4
heroes 5
NFS Rivals, NFS Shift 2, NFS the Run
It did it.

I would say it is probably that low quality power supply. Swap it for a tier 1 or 2 unit. http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html
