I kind of have a huge problem with my GPU. I recently finish building my new PC and I got the RX 480 8GB from Sapphire Nitro. At first I didn't see any problems, so I updated the driver to 16.9.2. After a bit I noticed my monitors were getting these weird black flashes. Nothing really bothering but it never happened on my old PC and I was running XFX 7800 HD card. but then this other problem started occurring. When I was playing Battlefield 1, at least long enough my screen will jump pop randomly and I get this oddly pixelated screen before blacking out and I would have to replug my dvi port to reset the monitor. At that point the computer already crashed.
So, I honest think it couldn't be my monitors because it never happened before. So today I updated the driver to 16.9.5, the WatchDogs 2 update, up to 5:30 pm PST everything was fine. No black flashes until I played 2-3 games of DotA 2 and all of a sudden I got the jump and the pixelated screen then into a black.
Do you guys think my RX 480 is faulty and that i need to RMA it?
