I have a Gigabyte R9 290x, and it works great when I game with no problems but after I quit the game and go back to the Windows desktop I get a lot of artifacting and after about a minute my PC will just shut off and then restart and the artifacting will reappear on the boot screen and I have to unplug my pc and then wait a few hours before it will go away. Let me know if you have any additional questions about my system or problem
