My GTX1060 has gotten some strange issue, sometimes it's not displaying video upon PC boot. Everything else works normally and Windows starts normal just without any signal from GPU. Fans are also working. I have to restart computer few times to get it running normally, after it starts(with video output) everything works fine including GPU; benchmarks, temperatures, quality - fine. I have tried different cables and ports(HDMI, DVI) and the issue is there. Cleaning card and reinstalling it didn't work neither. And this PC has been running for few years in this configuration without any issues. I suspect it could be "cold joints" but I don't want to toy with heatgun. Any takes?
