Ryzen 5 1500x Issues on new build.

Morning Guys & Gals,

I've got a bit of an issue with my brand new Ryzen 5 1500x. Currently running it absolutely stock, but no matter what its crashing.

I've just replaced my FX8320, 16gb DDR3 & MSI 970 Gaming motherboard with a Ryzen 5 1500x, Corsair Vengeance 3000mhz DDR4 8gb & a Gigabyte GA-AB350. I'm currently using my old R9 380x 4gb, Corsair H60 water cooler & Cooler Master RS750 PSU.  No matter what I do it seems to crash after a few mins of gaming. I've not even attempted overclocking yet.

 

When i say crashing, Windows is fine, but the game itself crashes to a black screen. Any help would be massively appreciated.
