I have an amd r9 280x, and due to some issues with a game(pirated) I had to manually restart my computer. Then, while I was playing another game I got a blue screen saying "windows has encountered an error and needs to close" and then it restarts. After that, in the windows experience index it shows 2.0 for gaming graphics. Before that, it was 7.9. Now, not a single game works. Please help!
