PC crashes while gaming

[Shadowcito]

Hi ! I'm losing my mind trying to figure out whats making my PC crash randomly.
Any and every thoughts will be very grateful.

So:
1) My setup:
- AM3+ FX 8120 8 CORE 3.1GHZ 16MB BLACK EDITION
- (brand new) COOLMASTER HYPER 212 X
- (brand new) MSI RADEON RX480 8GB DDR5
- GIGABYTE GA-880GM-USB3L DDR3
- 2 x DDR3 4096MB 1600MHZ KINGSTON HYPER X BLU
- 700W SENTEY BRP700
- Windows 10 Pro 64 bits

2) Tests I've done:
Prime95 and Furmark

At first I thought it was a heating issue, so I bought the COOLMASTER HYPER 212 X, but the crashes continued.
I've also unparked parked cores.
Nothing seams to work, randomly while playing game like Heroes of the Storm, Tomb Raider, Doom it just dies.

What can I try next ?

Thank you for reading
