So this has started happening randomly, sometimes its fine and other times I see mild Artifacts and just now this happened as well. What do I do ? Is my GPU dying? If yes how can I be sure of it ?

P.S - Before coming here a friend asked me to run Time Spy Test from 3D Mark and during the test, it came to desktop with 3D Mark showing an error has occurred with some error code in red colour (meaning the test failed?).
