Black screens on my new pc

[Weaponer]

My Games keep crashing, sometimes with a black screen, with the black screens i need to restart the pc

My system is 2 days old and consist of:

-16 gb ddr4 3200 (running at 2400)

-MSI B350 Krait Gaming

-Samsung EVO 860 500gb

-Evga 1070 ti FTW Ultra

-Evga 650 supernova g3

-Ryzen 5 2600x

what i have tried:

-Uninstalling and reinstalling nvidia drivers

-trying different drivers 

-removing and installing the graphics card

I had my ram oc to 3200 mgz ii put it back at 2400 mgz

My tems usually stay bellow 70 degrees

my games will crash anywhere from 5 min to an hour and 15 min of playing

sometimes they get blackscreen or they just close

try running games without the gpu installed and see if you still have crashes

do a clean install of windows

make sure you dont have malware r something on your pc
