So, I recently upgraded my pc to a new motherboard (ASrock B85M-DGS) and a new CPU (i5 4460). I already had my GPU (RX 480) for almost a year with no problems. Now when I launch Rainbow Six Siege, my display/screen goes black and I can't leave the game (nothing helps), but I can hear my friend over skype so the PC didn't fully crash.
I tried running stress tests on 3DMark and it passed every single one. I also looked at the temperatures and the hottest my CPU goes is 65-70C and GPU 70-80. I need help since it's annoying to constantly having to restart my pc.

Few things to try. Try a different cable you have connected to your TV. Verify the game cache on steam. Open the game in windowed mode and make sure the settings match your TV res and fps, some tv will work at 59htz/fps and not 60. Use ddu and do a fresh install of your graphics drivers.

It happens with Rainbow Six Siege (not all of the time) and once when running 3DMark. And I didn't get any errors, only a light black screen that turns into a dark black screen. Seems like it's happening only in full screen. It can't be my GPU since the games play normal with 60+ FPS
