I think for me it was a temperature problem. I made a little script to trace my GPU temp with nvidia-smi tool and as soon as it gets around 110°C the GPU is shutting down. I made an extensive cleanup of my case and also set all the fans to max rpms ( got a fan controller on my case) now I can watch streaming videos full screen at around 60-62°C. I understood that the GPU was shutting down because when I switched to "Plug&Play OS" in my BIOS, in the logs I found some new lines: ---------------------------------------------------------------------- Apr 23 20:53:33 dubu kernel: [12090.960976] NVRM: GPU at 0000:01:00.0 has fallen off the bus.
