Every couple of hours, really randomly I get a screen shake and I see a colorful bar going through my display. It takes maybe 0.1 sec. No raise in temps or anything like that.
It started happening about a month ago. I am wondering if it's PSU fault or GPU fault.
I have a Sapphire R9 390 Nitro. I bought it new in January and it's not overclocked and lightly used. I have warranty until January 2018.
Should I send it back, or replace my PSU? What can it be? I thought it may be drivers, but I just upgraded to latest and it's still happening.
The artifact appears once every few hours. I don't think I noticed it during heavy load, only during idle, when GPU is at <5% usage and I'm in Chrome / just doing stuff. What do?
It looks more or less like this, but lasts only about 0.1 sec: http://www.playtool.com/pages/artifacts/background010000.jpg
