GPU : MSI GeForce RTX 2070 SUPER VENTUS OC 8GB GDDR6 256-bit
PSU : Super Flower Leadex II Gold 650W

Hello everyone,

I've assambled the components 2 days ago.
When running any game, I get these random black screens which last about 1 to 2 seconds
This problem doesn't occur when not running a game .
I didn't spot any correlation between GPU temperature and these black screens since I experience them when the GPU is either below 50C , at 60C or 70C.
I have tried setting the GPU fans to max no matter the temperature but it did not help.

I have tried uninstalling and installing the latest nvidia drivers but to no avail.
I am still eligible to return the video card for 11 days , but so far I'm not completely sure what is at fault here.

I would greatly appreciate any advice
Thank you
