Problem with graphics "MSi Radeon R7 370 4GB" Artifacts?


I have problem with my graphics, in game i have some types of "dotted squares". This is happening since 2 months after buying that video card. In attachment you can see what problem it is on example of Minecraft, but i have it on League Of Legends or GTA 5 too. It's really anoying and I don't know what should I do. I downgraded drivers, updated, formated PC and still it's happening. Can anyone help me?
