Screen suddenly turns white. Is it the GraKa?

I was just waiting for a friend in the Fortnite lobby but suddenly the screen went black and then white. At first I thought he was broken. I switched it on again but it didn't work. I also tried Alt + F4 and Alt + Tab but nothing was displayed and it stayed white. I then restarted the PC and now everything is fine. Was it the graphics card? Got a Radeon 560 series

Is hardly due to the GraKa. Rather, their control was "insulted" by incorrect software requirements.

Thanks, but net is very helpful

Your question was "Was it the graphics card?" my answer was: NO.

What is your problem

Ka the other part has confused
