I just got a new graphics card for my PC and it is a Radeon RX-580 ARMOR 8G OC. I had it for at least a month now. Every so often little blue or red squares show up on my screen. Then my screen goes black for 3 seconds and it goes back to normal. It doesn't just happen when I'm gaming. Even when I'm browsing the internet or watching videos this happens. I have a feeling the graphics card I bought is a little broken. It is definitely not my monitor. When I play on my Xbox through my monitor this does not happen. I am really hoping for an answer to my question. I don't want to buy a new graphics card. Thank you.
