Does the music sounds like its stuttering? does it loop whenever the screen goes black? And you said this doesn't happen while you game?
I have the same issue with my 290X, however it seems to happen mostly when I game. Try checking the voltage going into the card, your bios might be setting it to an area lower than required. Also check for new drivers etc. etc.
Also, Has it been overclocked? Maybe we can work this one out together xD
i have the EXACT same issue as you have, i have no idea what is causing this error.
though i inspected my temperatures with a programm while playing a pretty recource intense game and my GPU got to 80 C ans CPU to 73.8 C which is quite high.
it happens only ingame too, and only when there are a lot of particles or something else.
private message me please, so we can work this out over steam or something else
